Here is another twist on this question; how does one actually measure the proper slope of the trailing edge of the keel to the bottom aft corner of the keel? It is easy to measure the distance from the corner of the transom to the hull intersection of the keel, but another useful dimension would be the distance from the corner of the transom to the bottom aft corner of the keel.
