In response to Nol's comments:

There'll be a lot more info published fairly soon, but in response to Nol's comments I'll outline my plans briefly.  I'm commencing building a 16.8m high performance cruising proa.  The leeward hull has been engineered using finite element methods to enable foiling on two foils placed at the extreme ends of this hull.  It may well be that I'll have to consider hydraulic steering, but the principal goal is to get the craft foiling on three foils - one under the windward hull and the two leeward foils.

With a fractured bone in my left hand, boat building is on hold while I research foil configurations.
