Why not simply carve on from the sole of a flip-flop and glue it on to the bow with some contact cement? Quick, easy, cheap.

I like the work that has gone into this proposal. A very good effort. Some comments follow. 1. General. - The concept does not check for the minimum draft. This is fine with me – I see no reason for the minimum draft limit anyway. (Let’s simplify the rules where practical.) - It might be a good ...

In an earlier post, I underatand Lester indicated that it was common to consider the word "ply" to mean from the same lot/bolt/roll of material. My dictionary calls the term "ply" to mean "a single thickness, fold or layer". And the ERS supports this with a similar "ply" defination with "a sheet of ...

Alan: Perhaps you are correct. Of the craft I have seen, none exceed the 60 mm value and some are quite shy of this hull depth, but I suspect that you have more knowledge of this than I (since you are in a hot bed of hull design and developement). Back when we had to record this data on the initial ...

If we ever do a spec update, we should consider changing one of our rules. Sei up the rules so that the keel/ballast does not extend beyond 360 mm below the bottom of the hull. This plus the 60 mm hull max equals teh 420 mm max right now. With a slightly shallower hull, the overall depth might be 5 ...

Why not simply have one of the "emergency" IOM rule changes that grandfather existing sails? Seems to be a simple way to address the problem. And there need not be any time limit either.

Lester makes a good point that we do not want to go overboard on any simplification of our Rules. But the converse is also true. But in this subject thread, we have to note that the text of C.7.7(a) uses the permissive word "may". So this Rule section allows, but does not require, a specific sheetin...

It seems to me that it would be better yet if the number system used either one, two or three digits.

I do not see any problem with such an arrangement. As you recognise, just about every boat has some degree of differential sheeting. The geometry of the jib movement is based on the location of the jib pivit fitting and the sheet attachment fitting (which I will call jib-sheet length -- JSL) and the...
