Abstract
A boat hull keel is disclosed which retracts into the boat hull on a fixed pivot. The pivot location is placed above the keel/hull bottom intersection, rearward of the major axis of the fully lowered keel and rearward of the keel trailing edge at the keel/hull intersection. The placement distances are large in terms of the maximum keel chord length. (measured at the keel/hull intersection.) This amounts to a novel location. The location of the pivot allows the keel rotation to create a change in the attitude of the boat hull.
