Fat Ass Sterns of New Boats

Denr:
I think that you have walked off the end of the earth on this one. Actually those of us who buy boats with powerful stern sections do so expressly because we do care about sailing ability.

The broader sterns that you are referring to in many cases is there to improve speed and exists because these designers care about sailing ability rather than the other way around. Bringing the center of bouyancy aft allows a finer bow for better upwind performance a more surface area through the run for better surfing and planning ability. It also allows some increased form stability without paying the snap roll penalty normally associated with form stability.

While wide sterns used cause a problem with pushing the boat''s bow down ,and jacking the rudder up out of the water, thereby causing wipe outs,a better understanding modeling of the hull form nor results minimizes changes in trim and steering issues.

I am more convinced more than ever that the people who criticize these designs have never sailed on a decent performing boat.
