Gary,

Just for the record, a full keel does not inherently offer a bit of added stability. And a full keel does not necessarily result in 'solid tracking'. From a design standpoint the reason that a full keel is no longer seen as the ideal cruising keel has to do with the problem with being able to produce enough stability to allow the boat to stand up to an efficient sailplan that is powerful enough to overcome the increased drag from the keel. There are work arounds but they come at a price in terms of some mix being harder to handle, especially in changing conditions, or less carrying capacity.

The reason that your boat does not heel much is that it has an exceptionally wide beam and therefore a lot of form stability, and very little sail area (SA/D less than 14) for its weight and drag. As a result your heel angle that has nothing to do with the shape of your keel. You would actually heel less if you had less drag.

Respectfully,
Jeff
