Glad to see that you finally agree that the 40class boat is a lot stiffer.

Since it seems that we are agreeing, I have to answer to a honest question

Regarding RM the ones from the two boats would not be that different.

What would be massively different is the GZ curve, the arm length curve. For the RM curve you have to multiply those values by the displacement of the boat and as the Oceanis weights about the double that will make things more even. In the end it would not be a considerable difference.
