Interesting but I don’t think we have the race officer skills to operate such a system.

At the 3RRYC club in Rickmansworth we are discussing ways of running the two classes together to give the smaller MH fleet more sailing days. Our area of the lake is roughly 60m x 40m with plenty of bouys to do zig zag courses. If we start the MHs 30 seconds earlier can anyone hazard a guess as to how many laps we might get in before we get finish line congestion. Any other ways of doing it gratefully received. Thanks Trevor

Hmmm. My ancient ISIS is consistently mid field without really trying. If my mind doesn’t wander mid race I can keep pace with the best boats in the club in 45 degree A rig conditions.

Surely the prebend is removed by putting tension on the back stay. If it still doesn’t match the luff curve of the sail then it’s the position of the prebend rather than the amount. The sailmaker should be able to tell you where to put it.

Put a lid on it.

Put a three inch length of 1/2 inch wide strap under the fin bolt to make a loop.

My limited experience with Futaba would suggest that they don’t like damp and corrode easily. Expect component failure.

That will go over the heads of most folk!

Inside a coffee jar lid is sometimes a soft plastic disk you can use.

You make them from the Sailsetc item. The bottle parts stays attached to the hull and you screw in the top part when changing rigs.

I got a 100mm lid from Vintage Food Cans on Etsy but I can't find a 95mm one. I searched for food can lids and pot lids and found some 95mm but they were for coffee cups and the like. Vickers could have had some specially made?

Much prefer this layout on my smallish iPhone. Haven’t tried desktop yet.

Sorry but I still use my Isis all the time!

Using Portsmouth Yardstick involves timing everyone’s race and calculating results. Anyway PYNs are applied to whole classes not individual boats. You just gauge your personal performance by your progress up the fleet.
