I am with Mary... Heavy conditions, heavier boat. Lighter conditions, lighter boat. Obviously there is a very large overlap in the moderate conditions range but on the extreme fringes I like Mary's angle.

30 knots on the SC20 at 12' wide and well over 400 lbs was was at times a very tenuous situation, skipping on top of the water at one point then standing on the nose a second later. Without the weight and beam I am sure that we would have dmaged the boat in some fashion.
