Rudders: since the cat was thrown backwards or sideways the kick up feature probably wouldn't have helped.
Backwards, it would have. Sideways, it should be strong enough.
Rigs: Rob what do you think of the swing-wing rig (see http://www.youtube.com/watch?v=m25fBUaz43g ) as an option to your designs? In theory and without any experience with such rigs they seem like a promising option.
Pretty much the same as Mike (as usual). The Pha ones are a bit agricultural and have too many strings, The Matin Bleu and Beneteau ones look much nicer. I worry about the leading edge in strong winds, but it does not seem to be a problem. I would need to go for a sail before committing. Would also like to see some relative costings.
Mike, don't build too small or any performance differences will be swamped by the excess weight. Quickest/cheapest is cheap ply with flat bottom (in both directions), straight sides and flat deck. 2 sheets would be long enough. Avoid screws in the play as much as possible. Lee hull needs to be deep enough to support the mast, say 10% of the length (may make it worthwhile putting some negative sheer in the deck, but I doubt it) and keep the beams (straight alloy tubes) out of the water. If you want any drawings, let me know.
