How and where can I buy or sell a boat?
If your a newcomer you will want to start sailing as soon as possible. Decide which class you are interested in. If it’s one of the DF Classes you can probably purchase a new boat from stock.
Buying a new boat for all the other classes will take some time to deliver. In some cases 6 months to a year. In this case it would be best to buy a used boat to get you sailing.
If you have already joined a club its likely there are one or two boats for sale by club members. We do have a classifieds section in our forum where you will find used boats. Do ensure that you follow the guidelines for purchasing which are available in the forum.
If you want a new boat then we recommend using one of our Suppliers who can found Here
MYA members can sell their unwanted boats in our classifieds section of the forums. Make sure you have a forum account as the forum is not directly linked to the members area.

What are the current membership renewal fees and what is the renewal process?
Subscription Fees
Subscription Year: 1st Jan – 31st Dec
In line with the Constitution, we announce the Membership Subscriptions for the following year in July. An email is sent to all MYA members and an announcment is made on our website.
You can find the current and renewal fees on our Joining the MYA page.
Renewals Process
Just after the AGM (end of November) our membership secretary sends out a renewals spreadsheet to all MYA Clubs. This email will go to the designated Club Rep or the person that deals with the Clubs membership (where we know).
The spreadsheet contains a list of the clubs current MYA members. The sheet must be returned by email or post by the 31st December indicating which members are renewing their subscription, and any alterations to the existing details we hold for those members. Please be aware that members do update their own profiles and in some cases may not have informed their club of a change, so please ensure the correct information is used.
Payment must then be made by the Club for the total number of members renewing. This can be made by Bank Transfer, online using a Debit or Credit Card, or by Cheque. We do urge clubs to use the first two methods as cheques often go missing in the post and create additional work our end.
All of this information, together with payment details will be included in the membership secretarys email to the Club, sent just after the AGM.
Please ensure we have the correct contact details for the Club Rep. Check this on our MYA Clubs page – “View Details” link https://www.mya-uk.org.uk/mya-clubs/
Once memberships are renewed, the membership secretary will inform the Club. The first batch of new membership cards and Yearbooks will be sent out early January, followed by futher batches later in January.

How do I learn the radio racing rules?
On the water experience at club and open event is the best place to learn together with reading the expert rule books. Bryan Willis’ ‘The racing rules in practice’ is very good as it shows typical racing situations and outlines the rights and obligations of the boats.
We have some excellent videos that will help understand the basics in our knowledgebase here
We have a beginners guide to the Racing Rules for Radio Control Yachts here
Or if you have specific question why not ask it in our Racing Rules forum? here

What does MYA Insurance cover?
The Association arranges on behalf of the individual Members, a Public & Products Liability Insurance policy that provides an indemnity limit of £5,000,000 per claim.
In order to ensure that it provides cover for the said individual Members, the policy is arranged in the name of ‘The Committee and members FTTB (for the time being) of The Model Yachting Association jointly and severally for their respective rights and interests’.
The basis of the policy is to provide indemnity where the Member is legally liable for injury to a Third Party or causes Third Party property damage or loss. The policy does not however cover damage to property in the care, custody or control of the said member. In the event of a Third Party Property damage claim the policy subject is subject to a £500 excess.
The policy provides indemnity for Members based in Great Britain Northern Ireland the Isle of Man and the Channel Islands and also extends to include occasional International Model Yachting events but excluding North America, Canada and territories where the UK Foreign Office recommends avoiding travel.
So now you know! Please note that over the years some misconceptions about what is and is not covered may have arisen (eg: Clubs are NOT covered), so please read the above as it is quite short and then, if you have any further questions, please notify either your District Councillor or the MYA Treasurer.

How to correct/calibrate weighing scales for measurement
Currently there is no IRSA,, ITCA or IOMICA prescribed system for calibration of weighing equipment. Please use the MYA approved system which describes the equipment required in detail and how it shall be used to calibrate the weighing equipment and take readings.
For use with IOM, 10R, 6M and A Class certification control and equipment inspection.
It can be accessed here

What is the difference between a Sail Measurer and a Class Measurer?
The skills and knowledge required to certify sails for the IOM, M, 10R, 6M and A Class classes are common across them all. Appointment as a MYA Sail Measurer is the basic/entry qualification and, once appointed, a Sail Measurer may certify sails of any or all of those classes. There is no obligation to do so; it is a permission.
The skills and knowledge required to certify the hulls, hull appendages, rigs and rigging of the IOM, M, 10R, 6M and A Class classes vary considerably. Appointment as a MYA Class Measurer for a particular class is the next step after becoming a MYA Sail Measurer.
The 36″ Class class rules does not require the measurer to be an official measurer. In this class appointment as a Class Measurer is required without prior appointment as an MYA Sail Measurer.
-
Can certified sails be supplied either for a certified boat or before the boat is certified? – Ten Rater
Can the sailmaker supply certified Ten Rater sails either for a certified boat (where the existing sail dimensions are matched) or before the boat is certified (where the official measurer supplies the necessary sail certification)?
Yes.
In the first case the sailmaker and his official measurer requires sight of the existing certificate. Sail sizes are checked against the certificate and the official measurer certifies the sails are required by the class rules.
In the second case the certified rig area, and the area of each sail of the certified rig, are found by entering measurements of the sails into the sail and spar calculation parts of the Ten Rater Certificate and Measurement Forms. The Rating of the boat is dependent on knowing the waterline length in addition to the certified rig area. However, the area of a sail of the certified rig which is to be marked on the sail (and on any smaller additional sail) by the official measurer is dependent on the sail dimensions only and is not, in any way, dependent on the waterline length.

How do I register a used boat in my name?
When a boat changes ownership
When a boat changes ownership the certificate ceases to be valid.
In most cases you can obtain a valid certificate by following the procedure described on the bottom of the certificate where you, as owner, sign to declare that you will maintain the boat in compliance with the class rules. Send the certificate to the class registrar – here.
Where the certificate does not contain this declaration you should use the change of ownership form available below. Send the certificate and completed change of ownership form to the class registrar – here.
When buying a boat that does not have a certificate
If the boat has been previously issued with a certificate but where it has been lost you may be able to obtain a replacement certificate. Send the completed change of ownership form to the class registrar.
If the boat has not been previously issued with a certificate you can obtain one by following the procedure given here – here.
-
Sail graphics – IOM
An owner wants to put some kind of identifying mark on his IOM sails to help identify his boat during close racing. Is there is anything in the rules preventing him doing this?
Yes.
The IOM class rules are closed class rules – to quote:
The class rules for the International One Metre Class are closed class rules in which anything not specifically permitted by the class rules is prohibited. Individual rules may require, limit, or permit as necessary.
Of the Section G rules (applicable to sails) the only clauses relating to the construction of the sails are G.3 and G.4. None of those rules permits marks or decorations on the sails other than sail shape indicator stripes which are limited in number and width.
-
Boat certification where the sails are already certified
When a boat is supplied with certified sails but where no other equipment is certified, what is the Official Measurer required to do?
Where the sails are sourced from outside the UK it may be advisable to check that the measurer who certified the sails is properly authorised to do so by his country’s World Sailing Member National Authority.
IOM Class
The Official Measurer completes the certification control forms as usual except for the sections relating to sail certification. Endorsing the forms to the effect that the sails are already certified will add clarity for the class registrar.
Marblehead, Ten Rater and A Classes
Where the sails are supplied with correctly completed certification control forms for the sails, the Official Measurer completes the other certification control forms as usual. All the forms are then sent to the class registrar. Note that for A Class sails the relevant measurements B and J would be marked on the sails.
-
Why is the weight of a complete boat, keel and rudder not required for certification control? – IOM
For the IOM the minimum weight of the complete boat, and the maximum weights of the keel and the rudder are specified in Section C of the class rules. Section C rules are those which apply to the competitor and boat at an event. Other Section C rules control the draught, hull depth and hull length.
All these measurements are inter-related and are affected by the competitor’s freedom to replace radio control equipment weights and positions as well as alter the placement and weight of the keel and rudder without having to have each minor change certified by an Official Measurer. In this way the class rules give complete freedom to the owner to work on his boat BUT with the responsibility that he shall ensure the weight and flotation is correct before racing.
Put another way, if the weight of boat, keel and rudder were certified the owner would be unable to alter any of them without having the equipment re-certified. History tells us that this restriction was too onerous for owners to tolerate. The current rules give the owners freedom to do what they were doing anyway, but within the class rules. However, they need to be aware that they remain responsible for checking the weight of the boat, keel and rudder.
It follows that, as weighing these items is not a certification matter, it is not necessary for an Official Measurer to carry it out. Owners often rely on the Official Measurer to carry out these checks for them as they will usually have access to suitable weighing equipment. Alternatively owners may invest in equipment accurate enough to do this for themselves or find someone else able to provide the service for them. Some clubs buy and maintain equipment suitable for their members to use and which can be used for equipment inspection at open events when competitors’ boats are checked for compliance.
-
Missing certificate – can I enter an event?
If you cannot find your boat’s certificate when preparing to travel for an international, MYA or major open event, all is not lost.
Assuming your boat has been issued with a certificate and it remains valid (the international and MYA Adopted class certificates have no expiry date) you will be able to invoke RRS 78.2 which allows you to give the race committee a signed statement saying that the certificate exists.
At world and European Championships you will need to produce the certificate or verify its existence before the end of the event.
At MYA events and any event using the MYA Standard Sailing Instructions you have 7 days to deliver the certificate or a copy to the race committee.
If no certificate is produced then disqualification from all races at the event follows.
For MYA events the same will apply to the Personal Number Certificate.
-
Unsure about the compliance of a feature of a boat?
If an Official Measurer you are bound by ERS H.1.2 which, where you are in any doubt, requires you to consult with the certification authority before signing a certification control form or signing an affected sail.
The certification authority in the UK for the MYA Adopted classes (FS and RC) is the MYA – please contact the MYA’s Technical Officer.
If an owner, builder or designer you can in the first instance check with a local Official Measurer. He should be able to guide you but cannot provide any official ruling or interpretation. This can only be provided by the relevant authority (IOMICA for the IOM, IMCA for the M, ITCA for the 10R, IRSA for the A Class, and the MYA for the MYA Adopted classes and FS variants of the international classes).

How is the length of a spinnaker pole measured in the Marblehead class? – Free Sailing
The relevant class rule in the FSCRS is:
4.4 Spinnakers and spinnaker pole
4.4.3 The length of the spinnaker pole shall not exceed 375mm, measured from the face of the mast (without fittings and rigging) to the attachment point of the spinnaker tack to the spinnaker pole.
The relevant ERS rule is:
H.3.3 Unless otherwise specified, measurements shall be the shortest distance between the measurement points.
A The length found in FSCRS 4.4.3 shall be the shortest distance.
NB It would be normal to require this measurement to be the largest distance between the two measurement points. Therefore MYA Council have will issue a Sailing Instruction that amends the wording of FSCRS 4.4.3 appropriately.
-
Can a sailmaker supply certified sails ready to use without further measurement?
In the IOM class, he can. The IOM class rules permit one or more persons at a sailmaker to certify the sails that they make. This process is called In-House Certification (IHC) and a special licence, issued by the Royal Yachting Association, has to be obtained in order to do this. The licence is granted in accordance with the World Sailing IHC programme.
However, obtaining the licence itself is not a simple process – and there are onerous contractual requirements that have to be satisfied. For example, should sails be found to be non-compliant at a later stage it may be necessary to recall them and re-supply compliant sails. The contract and relationship between the RYA and the sail maker is designed to protect the customers. There are not many sailmakers that go down this route – most prefer to hire the services of a local Official Measurer to carry out the task.
IHC is not considered appropriate unless sails are essentially ‘One Design’ in nature so, while IHC is possible for IOM sails, the other IRSA classes do not permit IHC of sails. However, nothing prevents a sailmaker from engaging an Official Measurer to check sails against the owner’s certificate and certify them before he supplies them to the owner. Note that in the A Class it is not necessary to have sight of the certificate before the Official Measurer can certify the sails as sail certification is independent of the boat.
-
How is the length of a spinnaker pole measured in the A Class? – Free Sailing
The relevant class rule in the FSCRS is:
5.5 Spinnakers and spinnaker poles
5.5.6 The length of the spinnaker pole shall not exceed “J”, measured from the face of the mast (without fittings and rigging) to the attachment point of the spinnaker tack to the spinnaker pole.
The relevant ERS rule is:
H.3.3 Unless otherwise specified, measurements shall be the shortest distance between the measurement points.
A The length found in FSCRS 5.5.6 shall be the shortest distance.
NB It would be normal to require this measurement to be the largest distance between the two measurement points. MYA Council will issue a Sailing Instruction that amends the wording of FSCRS 5.5.6 appropriately.
-
How is compliance of a spinnaker pole with FSCRS 4.4.4 and 5.5.7 tested? – Free Sailing
The relevant class rules in the FSCRS is:
4.4 Spinnakers and spinnaker pole
4.4.4 The spinnaker pole without fittings and rigging shall be capable of fitting within a cylinder of 20mm internal diameter, not shorter than the length of the pole.
5.5 Spinnakers and spinnaker poles
5.5.7 The spinnaker pole without fittings and rigging shall be capable of fitting within a cylinder of 25mm internal diameter, not shorter than the length of the pole.
Few spinnaker poles will be capable of fitting into the cylinder prescribed in the FSCRS unless their fittings are removed. Official measurers may have to decline to certify the equipment or use an alternative system i.e. use of a ring gauge. Where there remains doubt that the spinnaker pole spar will fit into the prescribed cylinder because of, for example, combined curvature and diameter, the spinnaker pole will have to be stripped of fittings to be tested for compliance in a suitable cylinder.
A Official measurers should be able to cope where necessary if equipped with suitable additional equipment and given suitable guidance in the class specific training material and certification control forms.
-
Can a genoa be used? – Free Sailing A Class
No specific reference is made to a genoa in the FSCRS. However, the class rule requiring the headsail clew to be attached to the headsail boom has been cancelled and a modest sized genoa-like headsail becomes permitted without using the normal headsail boom.
The size of a headsail is limited only by the half width restriction and the requirement not to extend forward of the forward edge of the foretriangle.
The Free Sailing Sailing Instructions alter the FSCRS as follows:
Add to C.8.4 (b)
C.8.4 (b) (4) The clew point shall not extend aft of the mast without fittings and rigging.
Regardless of the possibility of constructing a headsail that has dimensions and geometry similar to a traditional genoa, it is not permitted to use such a sail in the way that a genoa is normally used.

What is the correct course of action when a 36” class boat is presented for certification control with multiple/alternative hull appendage configurations?
The relevant class rules are:
C.4.1 (b) Except for boom counterbalance weights, ballast shall not be changed, moved or rotated relative to the hull.
E.1 (a) Except for rudders, the following are prohibited: retractable and or movable hull appendages.
H.1.1 (a) Except for the rig and sails and as in (b), (c) and (d) the boat, in racing trim, shall be capable of fitting into an open topped rectangular measurement box of internal dimensions 940mm (37″) long, 229mm (9″) wide and 279mm (11”) deep.
While it is clear that during an event class rules C.4.1 (b) and E.1 (a) prevent the hull appendages being moved to alternative positions (note also RRS 51), it is less obvious how a boat with alternative positions for the fin(s) and/ or ballast should be treated.
Class rule C.4.1 (b) does not apply at certification control but does not permit the ballast to be moved or rotated between events without having the boat checked by a class measurer to confirm that it fits in the box. The requirement for the boat to fit in the box is checked at certification control before a certificate is issued. The owner signs the certificate to pledge that alterations to hull and/or hull appendages that are measured (i.e. to check the boat fits in the box) will be checked before use.
It follows that, where there are alternative hull appendage configurations, each possible configuration shall be found to comply with class rule H.1.1 (a) before a certificate can be issued.

How do I get a personal sail number?
The MYA runs a scheme whereby, for a small fee, you can choose the number on your sail (00-99) and use this on the sails of all the IRSA and MYA class boats that you sail. This is restricted to 100 numbers in each district to avoid repetition. It does not give the skipper any preference at events or when booking to enter a Ranking or National Championships. The normal procedure for this is a first come basis.
To ask which numbers are available in your district please contact the Personal Sail Number Registrar. Contact details are in the Members Area or our officer contact page here
-
How do I get a boat number?
Reserve a hull registration number from the relevant class registrar.
The number will be reserved for you for twelve months after which time it may be reallocated if certification of your boat is not completed.
You can contact the Class Registrars using the form below.

How do I get my boat measured?
The certification service is provided FREE to all MYA members by the MYA, which is the certification authority for Model Yachting in the UK.
The certification procedure for a boat and it’s equipment in the international classes is well documented in Section A of the class rules, and your local official measurer will be able to provide guidance if you don’t already have a copy of these rules and related documents.
MYA members can find official measurers in the Members Area of our website here
More detailed information is available in our Knowledge Base here
- I have a question that is not answered here – how do I get an answer?
-
Can MYA members who are not interested in national or international competition race without having their boat and its equipment certified?
The Racing Rules of Sailing require us to use boats that have certificates and which comply with those certificates and their class rules. The class rules require the certification of equipment before a certificate for the boat can be issued.
However, club members by mutual consent may (for purely club events) ignore any part of the various rules they use. Having said that many clubs require members to have certified boats before they enter club races. Some rc sailors may not wish to belong to a club where a majority choose to ignore rules that do not suit them for one reason or another. Something to take into account before throwing the rule book out of the window, perhaps.

What is the correct course of action when hoisting a very small spinnaker? – Free Sailing
The relevant class rule in the FSCRS is:
2.5 Spinnakers and Spinnaker Poles
2.5.9 The length of the spinnaker pole shall not exceed 25mm outboard from the attachment point of the spinnaker tack to the spinnaker pole, measured along the axis of the pole.
A The practice of attaching very small spinnakers to the spinnaker pole more than 25 mm from its outer end in very strong winds is prohibited. A shorter spinnaker pole shall be used.

What is Equipment Inspection?
Equipment inspection is defined in the ERS as checking of equipment carried out at an event. Normally it is specified as part of the checking in procedure so it is mandatory in order to take part in the event.
The purpose of equipment inspection is to ensure that those items which are controlled/limited in Section C of the class rules i.e. all those items that the owner may change in the course of general maintenance and updating of his boat, remain compliant.
It usually happens as a matter of course, preferably before the start of an event, to permit owners to reassure themselves that their boat is compliant. This avoids the embarrassing prospect of finding the boat is non-compliant if a random check is made.
The person who carries out equipment inspection, the Equipment Inspector, will be appointed by the race committee. He is not required to be an Official Measurer. Acting in this capacity, perhaps alongside a more experienced person, is a good way to learn about measurement.
-
Why is the weight required for certification? – Ten Rater
The weight of the boat is recorded on the certification control form and becomes a measurement that is given on the boat’s certificate. It is then used as an indicator (but not proof) that the measured waterline length will be approximately correct if checked during equipment inspection at an event.
-
Why is the weight required for certification? – A Class/6 Metre
The weight of the boat is recorded on the certification control form and is used to compute the rating of the boat. It becomes a measurement that is given on the boat’s certificate. It is then used as an indicator (but not proof) that the boat has not been altered from its original configuration if checked during equipment inspection at an event.

Can the sailmaker supply certified Ten Rater sails either for a certified boat (where the existing sail dimensions are matched) or before the boat is certified (where the official measurer supplies the necessary sail certification)?
Yes.
In the first case the sailmaker and his official measurer requires sight of the existing certificate. Sail sizes are checked against the certificate and the official measurer certifies the sails are required by the class rules.
In the second case the certified rig area, and the area of each sail of the certified rig, are found by entering measurements of the sails into the sail and spar calculation parts of the Ten Rater Certificate and Measurement Forms. The Rating of the boat is dependent on knowing the waterline length in addition to the certified rig area. However, the area of a sail of the certified rig which is to be marked on the sail (and on any smaller additional sail) by the official measurer is dependent on the sail dimensions only and is not, in any way, dependent on the waterline length.

How is the length of a spinnaker pole measured in the Marblehead class? – Free Sailing
The relevant class rule in the FSCRS is:
4.4 Spinnakers and spinnaker pole
4.4.3 The length of the spinnaker pole shall not exceed 375mm, measured from the face of the mast (without fittings and rigging) to the attachment point of the spinnaker tack to the spinnaker pole.
The relevant ERS rule is:
H.3.3 Unless otherwise specified, measurements shall be the shortest distance between the measurement points.
A The length found in FSCRS 4.4.3 shall be the shortest distance.
NB It would be normal to require this measurement to be the largest distance between the two measurement points. Therefore MYA Council have will issue a Sailing Instruction that amends the wording of FSCRS 4.4.3 appropriately.
-
How is the length of a spinnaker pole measured in the A Class? – Free Sailing
The relevant class rule in the FSCRS is:
5.5 Spinnakers and spinnaker poles
5.5.6 The length of the spinnaker pole shall not exceed “J”, measured from the face of the mast (without fittings and rigging) to the attachment point of the spinnaker tack to the spinnaker pole.
The relevant ERS rule is:
H.3.3 Unless otherwise specified, measurements shall be the shortest distance between the measurement points.
A The length found in FSCRS 5.5.6 shall be the shortest distance.
NB It would be normal to require this measurement to be the largest distance between the two measurement points. MYA Council will issue a Sailing Instruction that amends the wording of FSCRS 5.5.6 appropriately.

How is compliance of a spinnaker pole with FSCRS 4.4.4 and 5.5.7 tested? – Free Sailing
The relevant class rules in the FSCRS is:
4.4 Spinnakers and spinnaker pole
4.4.4 The spinnaker pole without fittings and rigging shall be capable of fitting within a cylinder of 20mm internal diameter, not shorter than the length of the pole.
5.5 Spinnakers and spinnaker poles
5.5.7 The spinnaker pole without fittings and rigging shall be capable of fitting within a cylinder of 25mm internal diameter, not shorter than the length of the pole.
Few spinnaker poles will be capable of fitting into the cylinder prescribed in the FSCRS unless their fittings are removed. Official measurers may have to decline to certify the equipment or use an alternative system i.e. use of a ring gauge. Where there remains doubt that the spinnaker pole spar will fit into the prescribed cylinder because of, for example, combined curvature and diameter, the spinnaker pole will have to be stripped of fittings to be tested for compliance in a suitable cylinder.
A Official measurers should be able to cope where necessary if equipped with suitable additional equipment and given suitable guidance in the class specific training material and certification control forms.

Can a genoa be used? – Free Sailing A Class
No specific reference is made to a genoa in the FSCRS. However, the class rule requiring the headsail clew to be attached to the headsail boom has been cancelled and a modest sized genoa-like headsail becomes permitted without using the normal headsail boom.
The size of a headsail is limited only by the half width restriction and the requirement not to extend forward of the forward edge of the foretriangle.
The Free Sailing Sailing Instructions alter the FSCRS as follows:
Add to C.8.4 (b)
C.8.4 (b) (4) The clew point shall not extend aft of the mast without fittings and rigging.
Regardless of the possibility of constructing a headsail that has dimensions and geometry similar to a traditional genoa, it is not permitted to use such a sail in the way that a genoa is normally used.

Hull Registration Number – 36″ Class
Q Section D of the 36″ class rules requires the hull registration number to be permanently marked on an easily visible location on a non-removable part of the hull surface.
Is there any requirement for this to be of any minimum size?
A No. There is no minimum size requirement providing the hull registration number is easily visible. Any difficulty removing parts to enable the number to be inspected would suggest it is not easily visible.
-
Bumper size – 36″ Class
Q How is the forward 10 mm of the hull determined in the 36″ class?
A ERS H.3.1 states that words such as “fore”, “aft” etc are taken to refer to the boat in measurement trim. For the 36” class measurement trim is taken as the boat as placed in the measurement box. So the forward 10 mm of the boat, taken relative to the axes of the box, shall be of elastomeric material.
-
What is the correct course of action when a 36” class boat is presented for certification control with multiple/alternative hull appendage configurations?
The relevant class rules are:
C.4.1 (b) Except for boom counterbalance weights, ballast shall not be changed, moved or rotated relative to the hull.
E.1 (a) Except for rudders, the following are prohibited: retractable and or movable hull appendages.
H.1.1 (a) Except for the rig and sails and as in (b), (c) and (d) the boat, in racing trim, shall be capable of fitting into an open topped rectangular measurement box of internal dimensions 940mm (37″) long, 229mm (9″) wide and 279mm (11”) deep.
While it is clear that during an event class rules C.4.1 (b) and E.1 (a) prevent the hull appendages being moved to alternative positions (note also RRS 51), it is less obvious how a boat with alternative positions for the fin(s) and/ or ballast should be treated.
Class rule C.4.1 (b) does not apply at certification control but does not permit the ballast to be moved or rotated between events without having the boat checked by a class measurer to confirm that it fits in the box. The requirement for the boat to fit in the box is checked at certification control before a certificate is issued. The owner signs the certificate to pledge that alterations to hull and/or hull appendages that are measured (i.e. to check the boat fits in the box) will be checked before use.
It follows that, where there are alternative hull appendage configurations, each possible configuration shall be found to comply with class rule H.1.1 (a) before a certificate can be issued.

What are the Equipment Rules of Sailing?
The Equipment Rules of Sailing (ERS) contains, mainly, definitions of terms that are commonly used to describe parts of the boat and its equipment in a way that enables those terms to be used in class rules without ambiguity concerning their meaning. Where class rules invoke the ERS this enables class rules to be shorter, more precise, clearer, and to use terminology that is common with other classes.
A small part of the ERS is related to the use of equipment when racing.
All the IRSA, IOMICA and MYA class rules are based on the ERS terminology.
Note that some words above appear in bold text. When class rules invoke the ERS any term that appears in bold text has the meaning defined in the ERS. This gives the term a commonly understood meaning.
A boat is defined as:
The equipment used by the crew to take part in a race.
It includes:
hull(s)
structure(s) connecting hulls
hull appendage(s)
ballast
rig
sail(s)
fittings
boat corrector weights and
all other items of equipment used
but excludes
consumables
personal equipment and
portable equipment.Class rules are defined as:
The rules that specify:
the boat and its use, certification and administration.
the crew.
personal equipment and its use, certification and administration.
portable equipment and its use, certification and administration.
any other equipment and its use, certification and administration.
changes to the Racing Rules of Sailing as permitted by RRS 86.1(c).
The term includes rules of handicap and rating systems.The current ERS can be viewed here.

Unsure about the compliance of a feature of a boat?
If an Official Measurer you are bound by ERS H.1.2 which, where you are in any doubt, requires you to consult with the certification authority before signing a certification control form or signing an affected sail.
The certification authority in the UK for the MYA Adopted classes (FS and RC) is the MYA – please contact the MYA’s Technical Officer.
If an owner, builder or designer you can in the first instance check with a local Official Measurer. He should be able to guide you but cannot provide any official ruling or interpretation. This can only be provided by the relevant authority (IOMICA for the IOM, IMCA for the M, ITCA for the 10R, IRSA for the A Class, and the MYA for the MYA Adopted classes and FS variants of the international classes).
-
What is Equipment Inspection?
Equipment inspection is defined in the ERS as checking of equipment carried out at an event. Normally it is specified as part of the checking in procedure so it is mandatory in order to take part in the event.
The purpose of equipment inspection is to ensure that those items which are controlled/limited in Section C of the class rules i.e. all those items that the owner may change in the course of general maintenance and updating of his boat, remain compliant.
It usually happens as a matter of course, preferably before the start of an event, to permit owners to reassure themselves that their boat is compliant. This avoids the embarrassing prospect of finding the boat is non-compliant if a random check is made.
The person who carries out equipment inspection, the Equipment Inspector, will be appointed by the race committee. He is not required to be an Official Measurer. Acting in this capacity, perhaps alongside a more experienced person, is a good way to learn about measurement.
-
What is the difference between a Sail Measurer and a Class Measurer?
The skills and knowledge required to certify sails for the IOM, M, 10R, 6M and A Class classes are common across them all. Appointment as a MYA Sail Measurer is the basic/entry qualification and, once appointed, a Sail Measurer may certify sails of any or all of those classes. There is no obligation to do so; it is a permission.
The skills and knowledge required to certify the hulls, hull appendages, rigs and rigging of the IOM, M, 10R, 6M and A Class classes vary considerably. Appointment as a MYA Class Measurer for a particular class is the next step after becoming a MYA Sail Measurer.
The 36″ Class class rules does not require the measurer to be an official measurer. In this class appointment as a Class Measurer is required without prior appointment as an MYA Sail Measurer.
-
What are the Standard Class Rules?
The Standard Class Rules (SCR) is a template for class rules that choose to use that format for presentation. The overall content is set out as follows:
Section A Administration – describes class administration and issue of certificates
Section B Boat Eligibility – eligibility requirements for racing
Section C Conditions for Racing – what the sailor needs to know when racing
Section D Hull – rules relating to the hull
Section E Appendages – rules relating to appendages
Section F Rig – rules relating to the rig
Section G Sails – rules relating to sails
Section H Diagrams or other rules – diagrams, other rules not included elsewhereThe IRSA and IOMICA class rules all use this common format.
Generally a sailor needs to be aware of what is ion Section C as those rules govern what he can do with the boat and its equipment at an event.
Manufacturers of equipment need to be very aware of what is in the section relating to their products.
Measurers will find it easy to locate rules relating to the equipment they are measuring and can be confident that all the rule relating to sails, for example, are in Section G and are not also scattered elsewhere.

Sail graphics – IOM
An owner wants to put some kind of identifying mark on his IOM sails to help identify his boat during close racing. Is there is anything in the rules preventing him doing this?
Yes.
The IOM class rules are closed class rules – to quote:
The class rules for the International One Metre Class are closed class rules in which anything not specifically permitted by the class rules is prohibited. Individual rules may require, limit, or permit as necessary.
Of the Section G rules (applicable to sails) the only clauses relating to the construction of the sails are G.3 and G.4. None of those rules permits marks or decorations on the sails other than sail shape indicator stripes which are limited in number and width.
-
Boat certification where the sails are already certified
When a boat is supplied with certified sails but where no other equipment is certified, what is the Official Measurer required to do?
Where the sails are sourced from outside the UK it may be advisable to check that the measurer who certified the sails is properly authorised to do so by his country’s World Sailing Member National Authority.
IOM Class
The Official Measurer completes the certification control forms as usual except for the sections relating to sail certification. Endorsing the forms to the effect that the sails are already certified will add clarity for the class registrar.
Marblehead, Ten Rater and A Classes
Where the sails are supplied with correctly completed certification control forms for the sails, the Official Measurer completes the other certification control forms as usual. All the forms are then sent to the class registrar. Note that for A Class sails the relevant measurements B and J would be marked on the sails.
-
Why is the weight of a complete boat, keel and rudder not required for certification control? – IOM
For the IOM the minimum weight of the complete boat, and the maximum weights of the keel and the rudder are specified in Section C of the class rules. Section C rules are those which apply to the competitor and boat at an event. Other Section C rules control the draught, hull depth and hull length.
All these measurements are inter-related and are affected by the competitor’s freedom to replace radio control equipment weights and positions as well as alter the placement and weight of the keel and rudder without having to have each minor change certified by an Official Measurer. In this way the class rules give complete freedom to the owner to work on his boat BUT with the responsibility that he shall ensure the weight and flotation is correct before racing.
Put another way, if the weight of boat, keel and rudder were certified the owner would be unable to alter any of them without having the equipment re-certified. History tells us that this restriction was too onerous for owners to tolerate. The current rules give the owners freedom to do what they were doing anyway, but within the class rules. However, they need to be aware that they remain responsible for checking the weight of the boat, keel and rudder.
It follows that, as weighing these items is not a certification matter, it is not necessary for an Official Measurer to carry it out. Owners often rely on the Official Measurer to carry out these checks for them as they will usually have access to suitable weighing equipment. Alternatively owners may invest in equipment accurate enough to do this for themselves or find someone else able to provide the service for them. Some clubs buy and maintain equipment suitable for their members to use and which can be used for equipment inspection at open events when competitors’ boats are checked for compliance.
-
Missing certificate – can I enter an event?
If you cannot find your boat’s certificate when preparing to travel for an international, MYA or major open event, all is not lost.
Assuming your boat has been issued with a certificate and it remains valid (the international and MYA Adopted class certificates have no expiry date) you will be able to invoke RRS 78.2 which allows you to give the race committee a signed statement saying that the certificate exists.
At world and European Championships you will need to produce the certificate or verify its existence before the end of the event.
At MYA events and any event using the MYA Standard Sailing Instructions you have 7 days to deliver the certificate or a copy to the race committee.
If no certificate is produced then disqualification from all races at the event follows.
For MYA events the same will apply to the Personal Number Certificate.

How is compliance of a spinnaker pole with FSCRS 4.4.4 and 5.5.7 tested? – Free Sailing
The relevant class rules in the FSCRS is:
4.4 Spinnakers and spinnaker pole
4.4.4 The spinnaker pole without fittings and rigging shall be capable of fitting within a cylinder of 20mm internal diameter, not shorter than the length of the pole.
5.5 Spinnakers and spinnaker poles
5.5.7 The spinnaker pole without fittings and rigging shall be capable of fitting within a cylinder of 25mm internal diameter, not shorter than the length of the pole.
Few spinnaker poles will be capable of fitting into the cylinder prescribed in the FSCRS unless their fittings are removed. Official measurers may have to decline to certify the equipment or use an alternative system i.e. use of a ring gauge. Where there remains doubt that the spinnaker pole spar will fit into the prescribed cylinder because of, for example, combined curvature and diameter, the spinnaker pole will have to be stripped of fittings to be tested for compliance in a suitable cylinder.
A Official measurers should be able to cope where necessary if equipped with suitable additional equipment and given suitable guidance in the class specific training material and certification control forms.
-
What is the correct course of action when hoisting a very small spinnaker? – Free Sailing
The relevant class rule in the FSCRS is:
2.5 Spinnakers and Spinnaker Poles
2.5.9 The length of the spinnaker pole shall not exceed 25mm outboard from the attachment point of the spinnaker tack to the spinnaker pole, measured along the axis of the pole.
A The practice of attaching very small spinnakers to the spinnaker pole more than 25 mm from its outer end in very strong winds is prohibited. A shorter spinnaker pole shall be used.
-
At a FS event, when a Marblehead or A Class boat is protested for failure to comply with its certificate/class rules, and is found to have measurements that fall outside of any tolerances in the class rules, what is the correct course of action? – Free Sailing
At an event run using the Racing Rules of Sailing (RRS) the following clause applies.
When a protest committee finds that deviations in excess of tolerances specified in the class rules are not caused by normal wear and tear and/or do improve the performance of the boat, it shall penalise her.
Deviations within tolerances that do not affect performance may not result in a penalty. However, the FSCRS cancels this clause.
A The class rules require the boat to comply with her certificate. By removing permission not to penalise a boat that is found to be outside of class rule tolerances where performance is not improved, there is no alternative but to penalise.
-
At a FS event, if a protest hearing finds a competitor has deliberately or knowingly breached the class rules, what is the correct course of action? – Free Sailing
The IRSA Marblehead and A Class class rules documents refer cases of deliberate or knowing breach of class rules to the Racing Rules of Sailing process that deals with various forms of misconduct by competitors and/or their support persons. A wide variety of penalties is possible. No equivalent route is prescribed in the FSCRS to refer such cases to the FSYRR.
Note that
The FSYRR require a boat that cannot produce its certificate to be disqualified from the event. This seems remarkably severe considering the following:
A ‘clear-cut’ violation of the fair play/sportsmanship rule (which might be used in the case of a deliberate or knowing breach of the class rules) results only in disqualification from one board.
A gross infringement of (amongst other things) the fair play/sportsmanship rule may result in the competitor being disqualified from further events.
A There appears to be no clear serious sanction against deliberate or knowing breach of class rules.
-
How may a spinnaker be attached? – Free Sailing
The relevant class rule in the FSCRS is:
2.5 Spinnakers and Spinnaker Poles
2.5.4 A spinnaker shall have 3 points of attachment.
A The number of attachment points of a spinnaker is limited to three. As these are open class rules, the number of sheets, guys and halyards is un-limited and the attachment points are un-defined
-
Can a spinnaker be sheeted to a boom other than the main boom and headsail boom? – Free Sailing
The relevant class rule in the FSCRS is:
2.5 Spinnakers and Spinnaker Poles
2.5.8 A spinnaker shall not be sheeted to the main boom or headsail boom.
This is replaced by way of the FS Sailing Instructions by the following:
2.5.8 A spinnaker shall not be sheeted to any boom.
The Sailing Instruction change makes it clear that a spinnaker shall not be sheeted to any boom. Setting the spinnaker tack on the spinnaker pole is not affected by this – a spinnaker pole is not a boom.
NB The 36” class rules permit any rig to be used (open class rules, the rig is very un-restricted). There are no restrictions on the spars and rigging used to control a sail that is not a spinnaker.

How is the length of a spinnaker pole measured in the Marblehead class? – Free Sailing
The relevant class rule in the FSCRS is:
4.4 Spinnakers and spinnaker pole
4.4.3 The length of the spinnaker pole shall not exceed 375mm, measured from the face of the mast (without fittings and rigging) to the attachment point of the spinnaker tack to the spinnaker pole.
The relevant ERS rule is:
H.3.3 Unless otherwise specified, measurements shall be the shortest distance between the measurement points.
A The length found in FSCRS 4.4.3 shall be the shortest distance.
NB It would be normal to require this measurement to be the largest distance between the two measurement points. Therefore MYA Council have will issue a Sailing Instruction that amends the wording of FSCRS 4.4.3 appropriately.

Unsure about the compliance of a feature of a boat?
If an Official Measurer you are bound by ERS H.1.2 which, where you are in any doubt, requires you to consult with the certification authority before signing a certification control form or signing an affected sail.
The certification authority in the UK for the MYA Adopted classes (FS and RC) is the MYA – please contact the MYA’s Technical Officer.
If an owner, builder or designer you can in the first instance check with a local Official Measurer. He should be able to guide you but cannot provide any official ruling or interpretation. This can only be provided by the relevant authority (IOMICA for the IOM, IMCA for the M, ITCA for the 10R, IRSA for the A Class, and the MYA for the MYA Adopted classes and FS variants of the international classes).

What is Equipment Inspection?
Equipment inspection is defined in the ERS as checking of equipment carried out at an event. Normally it is specified as part of the checking in procedure so it is mandatory in order to take part in the event.
The purpose of equipment inspection is to ensure that those items which are controlled/limited in Section C of the class rules i.e. all those items that the owner may change in the course of general maintenance and updating of his boat, remain compliant.
It usually happens as a matter of course, preferably before the start of an event, to permit owners to reassure themselves that their boat is compliant. This avoids the embarrassing prospect of finding the boat is non-compliant if a random check is made.
The person who carries out equipment inspection, the Equipment Inspector, will be appointed by the race committee. He is not required to be an Official Measurer. Acting in this capacity, perhaps alongside a more experienced person, is a good way to learn about measurement.
-
Why is the weight required for certification? – Ten Rater
The weight of the boat is recorded on the certification control form and becomes a measurement that is given on the boat’s certificate. It is then used as an indicator (but not proof) that the measured waterline length will be approximately correct if checked during equipment inspection at an event.
-
What is the difference between a Sail Measurer and a Class Measurer?
The skills and knowledge required to certify sails for the IOM, M, 10R, 6M and A Class classes are common across them all. Appointment as a MYA Sail Measurer is the basic/entry qualification and, once appointed, a Sail Measurer may certify sails of any or all of those classes. There is no obligation to do so; it is a permission.
The skills and knowledge required to certify the hulls, hull appendages, rigs and rigging of the IOM, M, 10R, 6M and A Class classes vary considerably. Appointment as a MYA Class Measurer for a particular class is the next step after becoming a MYA Sail Measurer.
The 36″ Class class rules does not require the measurer to be an official measurer. In this class appointment as a Class Measurer is required without prior appointment as an MYA Sail Measurer.
-
Can certified sails be supplied either for a certified boat or before the boat is certified? – Ten Rater
Can the sailmaker supply certified Ten Rater sails either for a certified boat (where the existing sail dimensions are matched) or before the boat is certified (where the official measurer supplies the necessary sail certification)?
Yes.
In the first case the sailmaker and his official measurer requires sight of the existing certificate. Sail sizes are checked against the certificate and the official measurer certifies the sails are required by the class rules.
In the second case the certified rig area, and the area of each sail of the certified rig, are found by entering measurements of the sails into the sail and spar calculation parts of the Ten Rater Certificate and Measurement Forms. The Rating of the boat is dependent on knowing the waterline length in addition to the certified rig area. However, the area of a sail of the certified rig which is to be marked on the sail (and on any smaller additional sail) by the official measurer is dependent on the sail dimensions only and is not, in any way, dependent on the waterline length.

Boat certification where the sails are already certified
When a boat is supplied with certified sails but where no other equipment is certified, what is the Official Measurer required to do?
Where the sails are sourced from outside the UK it may be advisable to check that the measurer who certified the sails is properly authorised to do so by his country’s World Sailing Member National Authority.
IOM Class
The Official Measurer completes the certification control forms as usual except for the sections relating to sail certification. Endorsing the forms to the effect that the sails are already certified will add clarity for the class registrar.
Marblehead, Ten Rater and A Classes
Where the sails are supplied with correctly completed certification control forms for the sails, the Official Measurer completes the other certification control forms as usual. All the forms are then sent to the class registrar. Note that for A Class sails the relevant measurements B and J would be marked on the sails.

Missing certificate – can I enter an event?
If you cannot find your boat’s certificate when preparing to travel for an international, MYA or major open event, all is not lost.
Assuming your boat has been issued with a certificate and it remains valid (the international and MYA Adopted class certificates have no expiry date) you will be able to invoke RRS 78.2 which allows you to give the race committee a signed statement saying that the certificate exists.
At world and European Championships you will need to produce the certificate or verify its existence before the end of the event.
At MYA events and any event using the MYA Standard Sailing Instructions you have 7 days to deliver the certificate or a copy to the race committee.
If no certificate is produced then disqualification from all races at the event follows.
For MYA events the same will apply to the Personal Number Certificate.

Can a spinnaker be sheeted to a boom other than the main boom and headsail boom? – Free Sailing
The relevant class rule in the FSCRS is:
2.5 Spinnakers and Spinnaker Poles
2.5.8 A spinnaker shall not be sheeted to the main boom or headsail boom.
This is replaced by way of the FS Sailing Instructions by the following:
2.5.8 A spinnaker shall not be sheeted to any boom.
The Sailing Instruction change makes it clear that a spinnaker shall not be sheeted to any boom. Setting the spinnaker tack on the spinnaker pole is not affected by this – a spinnaker pole is not a boom.
NB The 36” class rules permit any rig to be used (open class rules, the rig is very un-restricted). There are no restrictions on the spars and rigging used to control a sail that is not a spinnaker.

How is the length of a spinnaker pole measured in the A Class? – Free Sailing
The relevant class rule in the FSCRS is:
5.5 Spinnakers and spinnaker poles
5.5.6 The length of the spinnaker pole shall not exceed “J”, measured from the face of the mast (without fittings and rigging) to the attachment point of the spinnaker tack to the spinnaker pole.
The relevant ERS rule is:
H.3.3 Unless otherwise specified, measurements shall be the shortest distance between the measurement points.
A The length found in FSCRS 5.5.6 shall be the shortest distance.
NB It would be normal to require this measurement to be the largest distance between the two measurement points. MYA Council will issue a Sailing Instruction that amends the wording of FSCRS 5.5.6 appropriately.
-
How is compliance of a spinnaker pole with FSCRS 4.4.4 and 5.5.7 tested? – Free Sailing
The relevant class rules in the FSCRS is:
4.4 Spinnakers and spinnaker pole
4.4.4 The spinnaker pole without fittings and rigging shall be capable of fitting within a cylinder of 20mm internal diameter, not shorter than the length of the pole.
5.5 Spinnakers and spinnaker poles
5.5.7 The spinnaker pole without fittings and rigging shall be capable of fitting within a cylinder of 25mm internal diameter, not shorter than the length of the pole.
Few spinnaker poles will be capable of fitting into the cylinder prescribed in the FSCRS unless their fittings are removed. Official measurers may have to decline to certify the equipment or use an alternative system i.e. use of a ring gauge. Where there remains doubt that the spinnaker pole spar will fit into the prescribed cylinder because of, for example, combined curvature and diameter, the spinnaker pole will have to be stripped of fittings to be tested for compliance in a suitable cylinder.
A Official measurers should be able to cope where necessary if equipped with suitable additional equipment and given suitable guidance in the class specific training material and certification control forms.
-
What is the correct course of action when hoisting a very small spinnaker? – Free Sailing
The relevant class rule in the FSCRS is:
2.5 Spinnakers and Spinnaker Poles
2.5.9 The length of the spinnaker pole shall not exceed 25mm outboard from the attachment point of the spinnaker tack to the spinnaker pole, measured along the axis of the pole.
A The practice of attaching very small spinnakers to the spinnaker pole more than 25 mm from its outer end in very strong winds is prohibited. A shorter spinnaker pole shall be used.
-
Can a genoa be used? – Free Sailing A Class
No specific reference is made to a genoa in the FSCRS. However, the class rule requiring the headsail clew to be attached to the headsail boom has been cancelled and a modest sized genoa-like headsail becomes permitted without using the normal headsail boom.
The size of a headsail is limited only by the half width restriction and the requirement not to extend forward of the forward edge of the foretriangle.
The Free Sailing Sailing Instructions alter the FSCRS as follows:
Add to C.8.4 (b)
C.8.4 (b) (4) The clew point shall not extend aft of the mast without fittings and rigging.
Regardless of the possibility of constructing a headsail that has dimensions and geometry similar to a traditional genoa, it is not permitted to use such a sail in the way that a genoa is normally used.

At a FS event, when a Marblehead or A Class boat is protested for failure to comply with its certificate/class rules, and is found to have measurements that fall outside of any tolerances in the class rules, what is the correct course of action? – Free Sailing
At an event run using the Racing Rules of Sailing (RRS) the following clause applies.
When a protest committee finds that deviations in excess of tolerances specified in the class rules are not caused by normal wear and tear and/or do improve the performance of the boat, it shall penalise her.
Deviations within tolerances that do not affect performance may not result in a penalty. However, the FSCRS cancels this clause.
A The class rules require the boat to comply with her certificate. By removing permission not to penalise a boat that is found to be outside of class rule tolerances where performance is not improved, there is no alternative but to penalise.
-
At a FS event, if a protest hearing finds a competitor has deliberately or knowingly breached the class rules, what is the correct course of action? – Free Sailing
The IRSA Marblehead and A Class class rules documents refer cases of deliberate or knowing breach of class rules to the Racing Rules of Sailing process that deals with various forms of misconduct by competitors and/or their support persons. A wide variety of penalties is possible. No equivalent route is prescribed in the FSCRS to refer such cases to the FSYRR.
Note that
The FSYRR require a boat that cannot produce its certificate to be disqualified from the event. This seems remarkably severe considering the following:
A ‘clear-cut’ violation of the fair play/sportsmanship rule (which might be used in the case of a deliberate or knowing breach of the class rules) results only in disqualification from one board.
A gross infringement of (amongst other things) the fair play/sportsmanship rule may result in the competitor being disqualified from further events.
A There appears to be no clear serious sanction against deliberate or knowing breach of class rules.
-
How may a spinnaker be attached? – Free Sailing
The relevant class rule in the FSCRS is:
2.5 Spinnakers and Spinnaker Poles
2.5.4 A spinnaker shall have 3 points of attachment.
A The number of attachment points of a spinnaker is limited to three. As these are open class rules, the number of sheets, guys and halyards is un-limited and the attachment points are un-defined

Hull Registration Number – 36″ Class
Q Section D of the 36″ class rules requires the hull registration number to be permanently marked on an easily visible location on a non-removable part of the hull surface.
Is there any requirement for this to be of any minimum size?
A No. There is no minimum size requirement providing the hull registration number is easily visible. Any difficulty removing parts to enable the number to be inspected would suggest it is not easily visible.
-
Bumper size – 36″ Class
Q How is the forward 10 mm of the hull determined in the 36″ class?
A ERS H.3.1 states that words such as “fore”, “aft” etc are taken to refer to the boat in measurement trim. For the 36” class measurement trim is taken as the boat as placed in the measurement box. So the forward 10 mm of the boat, taken relative to the axes of the box, shall be of elastomeric material.
-
What is the correct course of action when a 36” class boat is presented for certification control with multiple/alternative hull appendage configurations?
The relevant class rules are:
C.4.1 (b) Except for boom counterbalance weights, ballast shall not be changed, moved or rotated relative to the hull.
E.1 (a) Except for rudders, the following are prohibited: retractable and or movable hull appendages.
H.1.1 (a) Except for the rig and sails and as in (b), (c) and (d) the boat, in racing trim, shall be capable of fitting into an open topped rectangular measurement box of internal dimensions 940mm (37″) long, 229mm (9″) wide and 279mm (11”) deep.
While it is clear that during an event class rules C.4.1 (b) and E.1 (a) prevent the hull appendages being moved to alternative positions (note also RRS 51), it is less obvious how a boat with alternative positions for the fin(s) and/ or ballast should be treated.
Class rule C.4.1 (b) does not apply at certification control but does not permit the ballast to be moved or rotated between events without having the boat checked by a class measurer to confirm that it fits in the box. The requirement for the boat to fit in the box is checked at certification control before a certificate is issued. The owner signs the certificate to pledge that alterations to hull and/or hull appendages that are measured (i.e. to check the boat fits in the box) will be checked before use.
It follows that, where there are alternative hull appendage configurations, each possible configuration shall be found to comply with class rule H.1.1 (a) before a certificate can be issued.

H.1.1 (a) Except for the rig and sails and as in (b), (c) and (d) the boat, in racing trim, shall be capable of fitting into an open topped rectangular measurement box of internal dimensions 940mm (37″) long, 229mm (9″) wide and 279mm (11”) deep.
While it is clear that during an event class rules C.4.1 (b) and E.1 (a) prevent the hull appendages being moved to alternative positions (note also RRS 51), it is less obvious how a boat with alternative positions for the fin(s) and/ or ballast should be treated.
Class rule C.4.1 (b) does not apply at certification control but does not permit the ballast to be moved or rotated between events without having the boat checked by a class measurer to confirm that it fits in the box. The requirement for the boat to fit in the box is checked at certification control before a certificate is issued. The owner signs the certificate to pledge that alterations to hull and/or hull appendages that are measured (i.e. to check the boat fits in the box) will be checked before use.
It follows that, where there are alternative hull appendage configurations, each possible configuration shall be found to comply with class rule H.1.1 (a) before a certificate can be issued.

At an event run using the Racing Rules of Sailing (RRS), the use of specially textured surfaces are prohibited by RRS 53. There is no equivalent rule in the FSCRS. Can they be used on FS boats? – Free Sailing
The relevant class rule in the FSCRS is:
2.4 Skin Friction
2.4.1 A boat shall not eject or release a substance, such as a polymer that could improve the character of the flow of water inside the boundary layer.
A The effect of the omission of the text in RRS 53 is to specifically permit specially textured surfaces on FS boats.

At a FS event, when a Marblehead or A Class boat is protested for failure to comply with its certificate/class rules, and is found to have measurements that fall outside of any tolerances in the class rules, what is the correct course of action? – Free Sailing
At an event run using the Racing Rules of Sailing (RRS) the following clause applies.
When a protest committee finds that deviations in excess of tolerances specified in the class rules are not caused by normal wear and tear and/or do improve the performance of the boat, it shall penalise her.
Deviations within tolerances that do not affect performance may not result in a penalty. However, the FSCRS cancels this clause.
A The class rules require the boat to comply with her certificate. By removing permission not to penalise a boat that is found to be outside of class rule tolerances where performance is not improved, there is no alternative but to penalise.
-
At a FS event, if a protest hearing finds a competitor has deliberately or knowingly breached the class rules, what is the correct course of action? – Free Sailing
The IRSA Marblehead and A Class class rules documents refer cases of deliberate or knowing breach of class rules to the Racing Rules of Sailing process that deals with various forms of misconduct by competitors and/or their support persons. A wide variety of penalties is possible. No equivalent route is prescribed in the FSCRS to refer such cases to the FSYRR.
Note that
The FSYRR require a boat that cannot produce its certificate to be disqualified from the event. This seems remarkably severe considering the following:
A ‘clear-cut’ violation of the fair play/sportsmanship rule (which might be used in the case of a deliberate or knowing breach of the class rules) results only in disqualification from one board.
A gross infringement of (amongst other things) the fair play/sportsmanship rule may result in the competitor being disqualified from further events.
A There appears to be no clear serious sanction against deliberate or knowing breach of class rules.

How may a spinnaker be attached? – Free Sailing
The relevant class rule in the FSCRS is:
2.5 Spinnakers and Spinnaker Poles
2.5.4 A spinnaker shall have 3 points of attachment.
A The number of attachment points of a spinnaker is limited to three. As these are open class rules, the number of sheets, guys and halyards is un-limited and the attachment points are un-defined
-
Can a spinnaker be sheeted to a boom other than the main boom and headsail boom? – Free Sailing
The relevant class rule in the FSCRS is:
2.5 Spinnakers and Spinnaker Poles
2.5.8 A spinnaker shall not be sheeted to the main boom or headsail boom.
This is replaced by way of the FS Sailing Instructions by the following:
2.5.8 A spinnaker shall not be sheeted to any boom.
The Sailing Instruction change makes it clear that a spinnaker shall not be sheeted to any boom. Setting the spinnaker tack on the spinnaker pole is not affected by this – a spinnaker pole is not a boom.
NB The 36” class rules permit any rig to be used (open class rules, the rig is very un-restricted). There are no restrictions on the spars and rigging used to control a sail that is not a spinnaker.

How is the length of a spinnaker pole measured in the Marblehead class? – Free Sailing
The relevant class rule in the FSCRS is:
4.4 Spinnakers and spinnaker pole
4.4.3 The length of the spinnaker pole shall not exceed 375mm, measured from the face of the mast (without fittings and rigging) to the attachment point of the spinnaker tack to the spinnaker pole.
The relevant ERS rule is:
H.3.3 Unless otherwise specified, measurements shall be the shortest distance between the measurement points.
A The length found in FSCRS 4.4.3 shall be the shortest distance.
NB It would be normal to require this measurement to be the largest distance between the two measurement points. Therefore MYA Council have will issue a Sailing Instruction that amends the wording of FSCRS 4.4.3 appropriately.
-
How is the length of a spinnaker pole measured in the A Class? – Free Sailing
The relevant class rule in the FSCRS is:
5.5 Spinnakers and spinnaker poles
5.5.6 The length of the spinnaker pole shall not exceed “J”, measured from the face of the mast (without fittings and rigging) to the attachment point of the spinnaker tack to the spinnaker pole.
The relevant ERS rule is:
H.3.3 Unless otherwise specified, measurements shall be the shortest distance between the measurement points.
A The length found in FSCRS 5.5.6 shall be the shortest distance.
NB It would be normal to require this measurement to be the largest distance between the two measurement points. MYA Council will issue a Sailing Instruction that amends the wording of FSCRS 5.5.6 appropriately.

How is compliance of a spinnaker pole with FSCRS 4.4.4 and 5.5.7 tested? – Free Sailing
The relevant class rules in the FSCRS is:
4.4 Spinnakers and spinnaker pole
4.4.4 The spinnaker pole without fittings and rigging shall be capable of fitting within a cylinder of 20mm internal diameter, not shorter than the length of the pole.
5.5 Spinnakers and spinnaker poles
5.5.7 The spinnaker pole without fittings and rigging shall be capable of fitting within a cylinder of 25mm internal diameter, not shorter than the length of the pole.
Few spinnaker poles will be capable of fitting into the cylinder prescribed in the FSCRS unless their fittings are removed. Official measurers may have to decline to certify the equipment or use an alternative system i.e. use of a ring gauge. Where there remains doubt that the spinnaker pole spar will fit into the prescribed cylinder because of, for example, combined curvature and diameter, the spinnaker pole will have to be stripped of fittings to be tested for compliance in a suitable cylinder.
A Official measurers should be able to cope where necessary if equipped with suitable additional equipment and given suitable guidance in the class specific training material and certification control forms.
