Both are well designed boats the total RM would not be very different (due to the much bigger mass of the heavier boat) and the lighter boat will be massively stiffer.

Acording with what you say, the Oceanis, that is a lot less stiff, should be a better rough water boat than the 40class racer. It is not, not even close, there is a huge difference. The Class40 is a true bluewater boat capable of sailing in high latitudes and really heavy weather and that is not the case with the Oceanis. Therefore all your reasoning is wrong.

Ok.. lets see if you can back up your statements. The first place to start is to look at the stiffness. Since you say one is more stiff than the other.

What is the stiffness of each boat?
