This was what was in question, this statement of yours:

Sorry.. you are wrong.

Most of these boats have or more draft or more modern and efficient keels that will make the difference in RM even more meaningful. To my knowledge there are no other 29/33ft as tender in the market as the Jeanneau 30. |
and you say now about that:

B/D can only be used as a measure of stiffness when the hulls are identical and the weight is proportional the same. Clearly not the case here.
... I suggest you learn a bit about what stiffness means.

Here you have the hull of the 30i:
Here you have the hull of the 33i:
The Displ/lenght ratio is: 162.7 to 169.6
The very small difference in displacement/length has to do more with the much bigger B/D of the 33i then with any difference in the hull type or keel type. Both boats are even designed by the same NA.
Clearly it is the same kind of hull, the same kind of keel, the same kind of Displ/Lenght ratio.
How difficult is the check the data before posting?
