    摘要: The invention provides an improved nozzle assembly for waterjet-propelled watercraft such as a personal watercraft. In particular, the invention features an improved reverse gate assembly used to travel in a reverse direction. The reverse gate is linked to the steering-controlling waterjet outlet nozzle and pivots laterally with it to provide significantly enhanced steering response and control when the reverse gate is extended for reverse direction travel of the watercraft. The reverse gate actuation linkage assembly enables such linkage of the reverse gate and the steering-control nozzle member even when the nozzle is configured to pivot vertically (in addition to laterally) to “trim” the attitude of the watercraft in the water. Differential or laterally asymmetric design of the reverse gate compensates for vorticity or swirl in the waterjet to help ensure uniform watercraft performance when travelling in a reverse direction and turning either to the right or to the left.

    摘要: A control mechanism for a watercraft is described herein, said control mechanism comprising a steerable propulsion source, a steering controller for controlling said steerable propulsion source, a linking member connected to said steerable propulsion source, and at least one tab connected to said linking member, said at least one tab moveable between an inoperative position and an operative position whereby said at least one tab can be angled such that, in the operative position and when said watercraft is traveling upright in water in a substantially forward direction, a volume of water impinges on a top surface of said at least one tab thereby creating a downward and rearward force on said watercraft.

    摘要: 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.
