Abstract: A sailboat construction includes a hull having spaced first, second and third longitudinally extending lateral resistance elements which provide resistance to lateral movement of the boat under normal sailing conditions. The first and third resistance elements are spaced outwardly from opposite sides of the centerline of the hull in the forward portion thereof, and the second resistance element is aligned with the centerline in the aft portion of the hull. Because of the positions of the resistance elements, the boat is increasingly automatically turned into the wind as it is increasingly heeled over by the force of the wind, and as a result, the wind is normally spilled from the sails to return the boat to a more upright disposition before a capsizing situation can occur.
