Re: Full or fin keel?
Just have a look at two boats, with similar types of hulls, about the same size, one with 4.5T and a substantial part of its weight down on a bulb at the end of a 3m draft, the other one with 9T with much more proportion of weight in its hull and 1.55m of draft. 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.
40class racer is massively more stiff
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?
