Abstract: A sailboat having a novel hull shape, a fixed, shallow keel, dual rudders, and retractable, shallow dagger boards for sailing in shallow or shoal water is provided. The combination of features allows the boat to achieve performance sailing at all points of wind, and in both deep and shallow water. The hull preferably has a hydrodynamic shape which provides lift and lateral resistance to the hull when sailing. The keel is preferably shallow so that the boat may be sailed in shallow water and even beached. The draft of the keel is preferably related to the length of the hull measured along the waterline. In a preferred embodiment, there is 1 inch of draft for every 1 foot of waterline. The boat may also preferably include a set of retractable dagger boards located on opposite sides of the keel. A dagger board may be extended on the leeward side of the boat when the wind exceeds about 15 knots, in order to help prevent side slippage or leeway.
