New Vessel Control Unit from HamiltonJet

HamiltonJet introduced the

MouseBoat controller for its new blue

ARROW electronic control system.

The MouseBoat is an intuitive low speed control device for single or twin waterjet-powered boats, which together with blue ARROW is designed to make maneuvering in even the tightest situa- tions simple and safe.

The MouseBoat is a miniature boat hand piece that moves and acts much like a computer mouse. Whereas a stan- dard mouse moves a cursor up, down and sideways across a computer moni- tor, movement of the MouseBoat results in the same movement of the vessel, be it ahead, astern, or sideways. The

MouseBoat also adds a third axis, allow- ing rotation of the device to control ves- sel heading whether traveling ahead or astern, or in the "zero speed" mode.

It is designed to allow operators with little or no experience of waterjet propulsion to easily harness the full maneuvering capabilities twin waterjet units provide. For this reason the

MouseBoat is ideal in situations where there is a high operator turnover, when time given to instruction and training is limited, or where operators are required to be multi-functional on a range of ves- sels, such as in military and quasi-mili- tary applications.

The device makes low speed and docking control intuitive, so the opera- tor is able to react instinctively to chang- ing situations without having to think about what combination of wheel, reverse lever and throttle is required to perform a particular maneuver.

The blue ARROW system translates commands from the MouseBoat into steering control and differential move- ment of the waterjet's Astern Deflectors to provide sideways tracking.

Along with steering and ahead/astern control, the MouseBoat also manages low speed engine throttle. This is either done by moving or rotating the device further in the desired direction to increase boat speed or rate of turn, or by using buttons on the top of the

MouseBoat to increase or decrease engine rpm independently both in the devices centralized position and the degree of span. Spring-center action returns the MouseBoat to the central "zero speed"/straight-ahead mode when released.
