No matter how confusing your language you seem to fail to understand the most basic principles in what regards stability in what regards sailing and stiffness.
It is clear by the previous post, the Oceanis is more stiff could be even Massively more stiff
than the racer over more of the RM diagram. But you say I am confusing stiffness????
There are two ways of increasing stiffness in a sail boat: increasing beam and lowering the CG (increasing ballast or bigger draft). Increasing beam only increases stability at relatively low angles of heel, increasing CG has a lesser effect at low angles and increased effect with heel.
LOL.. you are mixing stiffness and RM. Careful.. you may get in trouble again.
