IMPROVEMENTS RELATING TO CONTROL OF MARINE VESSELS

摘要

A dynamic control system for a marine vessel having two or more waterjet units as the primary propulsion system of the vessel, for maintaing vessel position or velocity when in a dynamic control mode, comprises a position or velocity indicator to indicate vessel position or velocity or deviations in vessel position or velocity; such as a satellite - based positioning system indicator, or accelerometers as a relative position indicator, a heading indicator to indicate vessel heading or yaw rate or deviations in vessel heading or yaw rate, such as a compass as an absolute heading indicator or a yaw rate sensor as a relative heading indicator, and a controller to control the operation of the waterjet units to substantially maintain the vessel position or velocity, and vessel heading or yaw rate when the dynamic control mode is enabled.
