Abstract

In order to specify a hydrofoil (100), in particular a rudder, for water- borne vessels, in particular ships, with a trailing edge (20), in which the negative effects of vortex formation in the direction of flow behind the hydrofoil, and/or of Karman vortex streets, are reduced, a projecting body (30) is arranged at the trailing edge (20) for the purpose of reducing vortex formation. (Fig. 1)
