What is a Catalina smile? what is blocked wrong? The Jeanneau 379 can have three different keels. What is the one you are talking about?

Re: Full Keel

Crack at the hull keel joint it makes a smile shape. Keel is a L shape bulb.

Re: Full Keel

raymer:
B/D has everything/zero to do with the keel design.

The ballast could all be internal, up in the hull the way some of Ted Hood's big boats are. Or, like some of the old IOR boats were. The fin could be a non buoyant material with nom actual ballast. Or go further back to a time when all the ballast was internal. Hard to imagine but there was a time when outside lead ballast was considered only fit for radical racing yachts.

Your question is very broad.

In the audiophile world we have asaying, "Everything effects everything."
