Abstract
An automatic speed control system that provides desired watercraft velocity over land. The coupled algorithms correct engine speed and torque using inertia based measurements, GPS, and tachometer measurements, and the corrections are augmented and enhanced by velocity/speed and torque/speed relationships that are dynamically and adaptively programmed with real-time data collected during replicated operations of the watercraft in specified conditions.
