Keel Lift

Randolph,

The short answer to your question is, yes.

Here''s a link to a page which shows a diagram (scroll down to near the bottom) which illustrates all of the torques acting on a boat about its roll axis. It''s much easier to illustrate it than to try and describe it in words. The horizontal component of force on the keel (lift keeping the boat from sideslipping) should be shown acting midway (more or less) down the keel, rather than at the central axis of the hull. But other than that, this is a good illustration of what is going on to determine a boat''s angle of heel and rolling motion.
