Abstract

The invention relates to a watercraft (10), comprising a hull (12, 14, 16) at least intermittently located above a water surface (100), at least one measuring device (40) for measuring the distance (A) of the hull (12, 14, 16) to the water surface (100), and at least one T-bearing surface (220, 240, 260) guided beneath the water surface (100), wherein the angle of attack (α) of said T-bearing surface can be varied to control the distance (A). According to the invention, the T-bearing surface (240, 260) is arranged on a leeboard (24, 26) arranged on the side of the hull (12, 14, 16), said leeboard being movable relative to the hull (12, 14, 16). The invention further relates to a watercraft comprising a measuring device, which has at least one tow rod (42) that is arranged in an articulated manner on one of the hulls and glides on the water surface for measuring and controlling the distance (A) by means of an electronic control unit (50).
