Speaking of crew weights, we weighed in at 344 #'s, min wt for F18 is 330 for large sailplan.
It's 308 lb (140kg) min crew weight for the big sail plan if you carry corrector weights for the difference between crew weight and 330lb (150 kg).
Just in case any potential F18 sailors are put off by the need to supersize their meals to make min weight
