  • Patent number: 6357375
    Abstract: Apparatus for controlling thrusters in small water craft. A water craft is provided with a bow thruster and a stern thruster. A control panel in the helm has a thruster control stick for controlling each thruster and a HOLD device associated with each control stick. When the boat is brought into the desired position, for example, alongside a dock, the HOLD device can be pushed for one or both of the thrusters. When the HOLD is pushed, a signal is sent to a CPU to ignore any changes in position of the corresponding thruster control stick and to maintain the current amount of thrust in the corresponding thruster. In an alternative embodiment, a fore-and-aft thruster is provided as a third thruster, in addition to the bow and stern thruster. This fore-and-aft thruster is controlled analogously to the control of the other two thrusters, and is used to maneuver the boat forward and backward.
