ABSTRACT:
An improved apparatus for accurately maintaining the speed of a motorboat at a value set by an operator. Speed of the boat, and force on the boat due to a water skier are measured. Actual speed is compared to a desired speed set by the operator, and speed of the boat engine adjusted to minimize the difference between the desired speed and the actual speed. Engine speed is further adjusted to prevent or minimize changes in the speed of the boat caused by the forces on the boat due to a water skier. The device further incorporates features to reduce the likelihood of speed measurement errors due to a malfunctioning speed measuring device.
