Re: German Yacht Magazine Article on Full vs. Fin Keel
Sure, you are right as usual
Makes sense as I only post when you are wrong.
The Jeanneau 30 has a B/D ratio of only 24%, the Jeanneau 33i has 32%
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.
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.
And what do we care about the other boats you listed? They have nothing to do with the discussion at hand.
And clearly RM only is a measure of stiffness when the RM diagrams are identical shape. Clearly not the case here.
I can't imagine why you bring up the 33, when this test compares 30 foot and under boats.
So basically, your discussion of B/D has no meaning here. I suggest you learn a bit about what stiffness means.
