Wouter,

Can you point out the disadvantages of a more bouyant hull design, when sailed at the optimum 12 to 18 year old weight.

Will the boat become a "bucking horse"?

Will a more bouyant design for crew heavier than optimum raise the boat weight above the intended minimum?

I don't understand how a more bouyant hull can detract from performance.

Or do I need to simplify this more and look at it from a ratio standpoint. Is this like sailing an F16 with an 180kg crew and extra bouyancy is a must?
