  1. Hi Ian, On yachts where I don't want the acetone to attack paint I carry a bottle of Meths (methylated spirits) and kitchen towel. It takes a little more effort than with acetone, but cleans the residue from that adhesive sailcloth we use for deck patches. If it does not take it off directly, it causes the sticky residue to become congealed enough to remove with a finger nail. It also removes odd remains of water so one can apply a new patch to a clean surface - another radio skipper (Mike Parkington I believe) recommended me to try it for the water removal. I never re-apply patches, I treat them as 'consumables': I've lost significant successes due to water getting at the radio gear after sailing with a 'reused' patch.
  2. Ignoring 'rules' for a moment: surely the basic 'splitter' should be "which of the two skippers finished in front of the other the most?". If they both racked up the same number of '1st, 2nd, 3rd, etc places' which was furthest ahead of the other in those races? At Club level where there is only ever one group of boats racing together, then each 'heat' is a race and the collection of races at each session (day) is an event - hence RRS A8 applies. In most cases for a club a Series is the collection of events that take place throughout a sailing season to enable some sort of Trophy to be awarded at the end of a season. For that series a sensible, easy to compute, solution is to make only a selected group of events to count towards the Trophy: an example might be "a skipper's best seven events from a series of twelve". For that computation one can use a variation on the formulae used to compute the ranking event positions. Using the 'half the number of events in a series plus one' calculation coupled with a ranking-like scoring guarantees that there will almost certainly be an absolute winner. Over a season where different numbers of yachts appear at each event the 'ranking-like' scores will ensure that even the most closely matched two or three skippers will get slightly different contribution scores for any second, third, or other places for an event. Only the first place will be consistent with 100 'points'.
  3. Just catching up on my reading and spotted the comment about steering rack prices: just how many steering racks does one car need during its life? I would have thought - just the one it came with, surely they are like dogs - for life! Sixes last a lot longer! A Six would go in the car pictured. Removable lead on the passenger floor: hull bow first in the passenger area; mast and boom assembly between the head restraints (might need a hole in the rear window of the hood); sails in a short tube of soil pipe; radio gear in the luggage box; skipper in the driving seat and you're ready to go.
  4. I have been in similar spot during seeding races for a 'major' event when, as PRO, I had two such requests in separate seeding heats. Both were similar in that they affected a Starboard tack yacht approaching the finish which became hooked on a following, give-way, boat still 'running' to the leeward mark(s). My protest committee (seasoned sages with years of experience) advised that in such cases, because the protesting yacht was on the last leg of the course, the only fair redress was to award its finishing position as where it was in the 'running order' at the time of the incident. So, if the yacht was the third in the line of yachts approaching the finish at the time it was 'taken out' and had to be rescued (technically disabled as the result of the actions of a 'give way' yacht) it should be awarded third place in that heat. This seems the fairest approach for this particular situation and is not too difficult to write into any management procedure: however it does require race officials to be on their toes and observing the yachts - exactly what properly trained observers should be doing - so the yacht's position can be confirmed. Redress for activities on other legs of the course are more appropriately addressed by some average scoring system which, as you suggest, should be related to the seeding heat size and the yacht's performance during part of the rest of a regatta. In multi-day events, perhaps the average should only be based on other races on the same day as the seeding race(s) took place; assuming that Race 2 and beyond are sailed on the same day as seeding. Skippers often have completely different performances on other days of the longer events. The other factor is that redress should really only be considered for a protesting yacht which has been disabled by the actions of a yacht which loses the protest! This is something that definitely needs addressing. Mike Kemp

    Hull Strength

    It's a bit late to respond but, as no one else has bothered, I'll chuck in a comment as a possible solution. My original I0M, a 'Rhythm' carrying the number 7 (yes just 7 as hull number) is a hard chine built with ply panels and one inch wide (25mm) glass tape along the inside of the joins. It has one coat of 'fluid' SP resins epoxy inside and out and is finished off, on the outside, with a two part International yacht paint. It is still 'true' and I am considering putting its patches back on to see how it measures up to the current crop of I0Ms.
  6. I have just attempted to go to the recommended 'sailwave' site to see what that spreadsheet looked like and my Anti-Virus software stopped me with a message that the site is 'unsafe', being 'a known dangerous website'! Better follow the advice and use HMS - it may be a bit over the top for your local club mornings, but it will do the job.
  7. John, A bit late, sorry, if you go to the Sailsetc site URL http://www.sailsetc2.com/store/index.php/download/ and look for: RP-14E M swing rig GIZMO plan This gives you four pages of diagrams showing how the GIZMO is set up: it doesn't exactly explain how it works, but once you have put the various bits in place and strung it up correctly I guess experience of its use and, maybe, a knowledgeable club mate will eventually lead to 'cracking it'. I don't have experience of it, my old No Secret swing rigs were much simpler devices. I have no connection with Sailsetc apart from being a customer. Mike
  8. This may be a bit late for you but I have only just spotted your post. I am not really a fan of long push-pull servo links - too much risk of failure through passing over-centre and locking the rudder at the wrong moment. I am a long time user of a closed loop wire system for linking servo to rudder using what look like mini winch drums at each end. They have the advantage of enabling a rudder throw which is different to the servo movement - make the 'drums' of different sizes. They can also provide a more positive, less 'lossy', connection. It is a 'home workshop' solution where a small lathe is handy, to turn up one's own fittings. A wire system could easily pass through the necessary angles to meet your need, passing over, probably under, guide pulleys or hard metal guides on their way. An alternative would be to use a closed loop of the bendy plastic push/pull rods used in some model aircraft installations - they should be able to accommodate the necessary angle changes in your yacht as long as the servo and rudder stock are far enough apart to keep the bends to as large a radius as possible. Either system is going to involve some loss of energy so you will almost certainly need a more powerful servo than normal. Maybe we shall bump into one another now I have my '6' back on the water (us, not the boats) when yours gets wet. Best wishes, Mike
  9. I spotted this thread while browsing the forum and found myself smiling and wondering if Bill's database included entries for Eels, Jelly Fish, and flexible plastic bags? Catching an eel or jelly fish on a fin or bulb is, indeed, something else and results in a 'call' that is definitely not in the published rules of sailing!
