Jesus, I give up on you Bryce
You fail to acknowledge even the most obvious facts
So you have doubts that a 40 class racer is more stiff than a 40ft Oceanis?
The 40 class racer has much more hull form stability, being much beamier with a much flatter hull and the 40class boat has also a much bigger B/D not to mention that it has all ballast in a torpedo at the end of a 3 m draft while the Oceanis has only a 2 m draft and a keel with the weight more distributed.
How the hell do you think stiffness it is obtained in a sailboat?
I am out!
Hey guys, you can keep scratching your heads
