Arrays of parallel, substantially fore and aft oriented vortex generators are positioned on the keel and rudder of a sailboat to induce vortices at the surfaces of the keel and rudder for the purpose of reenergizing the boundary layers in the water flow past the keel and the rudder to increase the lateral lift in the horizontal plane and to thereby avoid increase in drag associated with keel and rudder stall at high angles of attack with the relative water flow. Similar arrays for the same purpose may be attached to other underwater stabilizing members such as skegs, keel winglets, centerboards, etc.

A sailboat keel having opposing surfaces with a vertical span and a fore and aft extending chord, comprising a plurality of spaced vortex generators aligned in a row in the direction of the span and extending laterally from the keel and aligned substantially with the chord, wherein said plurality of vortex generators comprise a continuous strip adapted for attachment to the surface of the keel, and a plurality of integral vortex generators extending therefrom.
