A control mechanism for a watercraft includes a selectively movable flap connected to an actuator, which moves the flap into and out of the flow of water to affect steering, deceleration and trimming. The flap is recessed with respect to the lower surface of the hull so that it does not create drag at high speeds. The flap may be a portion of the ride plate, may be disposed in a recess in the bottom of the hull, or may be disposed on the stern above the bottom of the hull.
