Hull flex in heavy weather

[Whimsical]

Yes Rob lives about 10 minutes from me and we have had several discussions. He will be building masts and booms for 3 12.3 Wilderness Bi-rigs, mahnamahna, mine and another one but I forget his name.
Mine will be a little more unusual again. I want them to fold down so I can get under a local 7 Mtr bridge. The hindge will be located just above the stack hieght of the main. I have discussed this with Rob and he thinks it is entirely feasable . I suppose the nay sayers will have a field day with this idea. But to them . It will look quite odd though with them folded down.
Already have 130 Kg of carbon tow ready.

As I see it, your need to fold the mast(s) just increases the advantages of the bi-plane to your application - no standing rigging to have to fold, and two short masts will be easier to handle than one tall one. I'm still curious to see how well they will sail though.

While I am curious as well I am fairly convinced it will sail quite well. Schionning made a prototype @ 8 mtr called Radical Bay. Two more were made and reside in Thailand where they seem to compete quite well even without a spinaker. The major difficulty seems to be a square reach where the windward sail blankets the leeward. Apparently if the windward sail is let out to feed air to the leeward sail it sort of becomes one foil which while not perfect is reasonable. I think I can live with that given the other advantages.
