But to specifically answer your question, Brian: I'm not ready to post specifics yet, as I'm still early in the design spiral. But to get what we want, its going to be between 50 and 100' LWL, between 7.5 and 9' beam, about 10,000 lbs loaded displacement, sandwich e-glass/vinylester, twin 60HP outboard, several high performance windsurfer rigs and a ballasted centerboard for positive drive roll stabilization. All of the above are from trade studies, they were not driving requirements. The driving requirements are: clear view of horizon sitting, sleeping, and standing; excellent ventilation; sufficient galley for gourmet meals; sufficient hanging lockers for nearly all clothes (avoid mold!); wide open interior to greatest extent possible; low total cost of ownership and low peak cash flow requirements; go anywhere we want to go, but that includes avoiding bad sea conditions and careful routing (easy to do without time constraints); 2500 miles for less than $1000 at expected future fuel prices ($10 per gallon). All of the above are easy to achieve only if SL is kept below 1, and DL is below 20 -- really, about 4 to 6! But very easy to achieve if and only if L is quite long. Sounds bizarre, but do the engineering, and its pretty straightforward, pretty much all about the structural engineering.
