Whoa.. a 30i is a particularly tender boat??? Clearly it is representative of a stiff production boat of the 30 foot size compared to the others. The test clearly shows the more comfortable boats are heavier boats with more mass righting moment.

It would no be more comfortable, or at least it will have a completely different motion:.
No, clearly comfort is related to mass and associated hull/keel design.. I am continually amazed that this simple fact seems to escape you.

I also don't see Hunter and Catalina which traditionally have heavier boats equivalent to the Oceanis which tends to be lighter.

Sorry.. you are wrong.
