  • Differential bucket control system for waterjet boats
    Patent number: 6386930
    Abstract: A waterjet-driven boat has a reversing bucket for controlling forward/reverse thrust and a rotatable nozzle for controlling sideward forces. A bucket position sensor is connected to the reversing bucket, and the bucket is controlled using the output of the position sensor to enable the bucket to be automatically moved to a neutral thrust position. Similarly, a nozzle position sensor is connected to the nozzle, and the nozzle is controlled using the output of the nozzle position sensor so that the nozzle may be automatically returned to a zero sideward force position. A joystick with two axes of motion may be used to control both the bucket and the nozzle. The joystick has built-in centering forces that automatically return it to a neutral position, causing both the bucket and nozzle to return to their neutral positions.
