I agree with you completely there Andy, and I think based on that, builders should seek advice much more often from the TechSC or whoever before introducing these gimmicks, as IOMICA advice suggests. This is going to happen on a cold day in hell; what's the old saw: "ask permission, seek denial"? I...

I don't have any doubt that the swivel attached at the bottom of the hull is "legal"; the method follows all the prescriptions of the rule, only it plays fast and loose with the conventional notions that may have been "assumed" by the language of the rules. If you really want to insist that what is ...

Besides being of dubious, imaginary or trifling utility, this "swivel down the hole" stuff is, as Ole Peder pointed out, an egregious example of playing the loopholes. I, for one, would favor a change in the rules that explicitly requires the moving parts of jib swivel/attachment to be entirely abov...

Dont confuse Event Measurement with Fundamental Measurement. Sorry, my mind missed the "event" (not the first time!). Your point is well taken; obviously if one wants to ensure that each rig is kept to within 5 mm of its original height, one would have to measure its position before racing begins.

Think about full-size boats with genoa jibs: it's an advantage aerodynamically to actually have the jib overlap the main; the idea is that the two sails are acting as a single airfoil, with a slot that improves performance of both.

The rule you reference means that the whole keel, except for the bottom 60 mm, must pass through a slot 20 mm wide. This limits, for instance, the width of a fillet or fairing that one might add at the point the keel meets the hull.
