Re: Full or fin keel?
LOL.. you best quit while you are no so far behind.
I did not say definitively it was stiffer, could be. ...
Is the Racer 40 stiffer. Probably,
Probably means that there is a big chance to be or it is a way not to say exactly that it is
Stffness is invariably created by hull design.. plain and simple. ...
So if on the same boat I would increase significantly the ballast, or put the same ballast a lot deeper (bigger draft) I would not get a more stiffer boat? and as "stiffness (is) the ability of the boat to resist the heeling force of the sails" it would not be a boat that heel less carrying the same amount of sail?
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.
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.
