While we are thinking inside the bigger box, I think we might remember that the preconception of difficult compound curves can also be thrown out with short high volume hulls that still must exceed hullspeed. If the stealth bomber can be made from flat sheets... While true planing hulls are impractical, I suspect that the example of boat builders building these complex hull shapes for pleasure boats, only to find that the high powered engines lead to "... hull shape doesn't matter, you plane anyway" may be worth considering. Similarly a "lift assisted hull" shape can be very practical to build if it has horsepower (sail area and beam) and has to be short anyway. Catamarans are unique in having weight transfer related to driving force. Let's use these characteristics, and build a fun, sailing machine, in the spirit of this class.

Bill,
mate still pushing credability..
Still a long way between Phill's carbon/kevlar (foam?) Paper Tiger at $4500 AuD a platform and your $15,000 USD..

If one uses 11 meters of 200 gm twill per hull.. That is 2 layers outer & one inner.. Over a foam core.. Now a quick check of carbon prices you in the US can purchase 200 gm twill at $ 14.25 ..

i agree about the simple shapes having speed potential. phil bolger, master sharpie designer, writes that if 1/2 the included angle of the bow equals the angle of the slope of the bottom as it rises to meet the stem, the the waterflow is equalized on the sides and bottom with a minimum of turbulence and drag. anyway i like simple designs and hope to come up with some kind of lightweight boat for my H14 rig.
