The weighted bulb can be canted up to 55 degrees either side of the boat's plumb line, using a hydraulic cylinder which is actuated by an electric motor, button-controlled from the cockpit helm position. It has dual fore-and-aft linked

Operational history

In a 2001 review in ''Sailing World'' Peter Danjou wrote, "I test-sailed the Schock 40 in San Pedro, Calif., during the Cabrillo Beach YC's Winter Series and can report the new boat is light, narrow, and very fast. The PHRF rating of -6 for wind-ward/leeward racing only begins to tell the story. I wouldn't have believed it if I hadn't seen it with my own eyes, but this 40-foot displacement boat beat an 18-foot skiff (sailed by Howard Hamlin) to the second weather mark in 12 to 15 knots of breeze."
