A watercraft includes a watercraft control mechanism that is capable of steering, decelerating, and/or trimming a watercraft without causing the stern to elevate and the bow to dive; steers or assists steering in off-power situations; steers, trims and/or decelerates a watercraft, or assists in steering, trimming, and/or decelerating a watercraft that can be stowed or retracted to minimize hydrodynamic drag at high speeds; steers, trims and/or decelerates a watercraft, or assists in steering, trimming, and/or decelerating a watercraft that does not become clogged or jammed by seaweed or flotsam or foreign objects floating in the water; and decelerates or assists in decelerating a watercraft in a smooth and stable manner when the watercraft is travelling at high speeds.

What is claimed is: 1. A watercraft comprising: a hull including a transom; a steering mechanism disposed on the watercraft; a water jet propulsion unit disposed on the hull and including a movable steering nozzle operatively connected to the steering mechanism for directing a water jet produced by the unit for steering the watercraft; a steering vane support pivotably mounted on the transom spaced apart from the water jet propulsion unit and pivotable about a substantially horizontal axis between a steering-vane-operative position and a steering-vane-inoperative position; a steering vane pivotably supported on the steering vane support and pivotable about a substantially vertical axis and operatively connected to the steering mechanism. 2. A watercraft comprising: a hull including a transom; a steering mechanism disposed on the watercraft; a water jet propulsion unit disposed on the hull and including a movable steering nozzle operatively connected to the steering mechanism for directing a water jet produced by the unit for steering the watercraft; a first steering vane support pivotably mounted on the transom spaced apart from and to the port side of the water jet propulsion unit and pivotable about a substantially horizontal axis between a first steering-vane-operative position and a first steering-vane-inoperative position; a first steering vane pivotably supported on the first steering vane support and pivotable about a substantially vertical axis and operatively connected to the steering mechanism; a second steering vane support pivotably mounted on the transom spaced apart from and to the port side of the water jet propulsion unit and pivotable about a substantially horizontal axis between a second steering-vane-operative position and a second steering-vane-inoperative position; a second steering vane pivotably supported on the first steering vane support and pivotable about a substantially vertical axis and operatively connected to the steering mechanism. 3. A watercraft comprising: a hull including a transom; a steering mechanism disposed on the watercraft; a water jet propulsion unit disposed on the hull and including a movable steering nozzle operatively connected to the steering mechanism for directing a water jet produced by the unit for steering the watercraft; a first steering vane support pivotably mounted on the transom spaced apart from and to the port side of the water jet propulsion unit and pivotable about a substantially horizontal axis between a first steering-vane-operative position and a first steering-vane-inoperative position; a first steering vane pivotably supported on the first steering vane support and pivotable about a substantially vertical axis and operatively connected to the steering mechanism; a second steering vane support pivotably mounted on the transom spaced apart from and to the port side of the water jet propulsion unit and pivotable about a substantially horizontal axis between a second steering-vane-operative position and a second steering-vane-inoperative position; and a second steering vane pivotably supported on the first steering vane support and pivotable about a substantially vertical axis and operatively connected to the steering mechanism; the steering vane supports pivoting between their steering-vane-inoperative positions and their steering-vane-operative positions in response to changes in water pressure of water flowing past the hull.
