Abstract:
An improved watercraft and propulsion system is disclosed for moving a watercraft such as an amphibious vehicle or a speed boat from 0 velocity to speeds in excess of 20 miles per hour. Each watercraft includes water propulsion systems which are preferably pivotally mounted on or near the rear end of the watercraft for pivotal movement between a transversely aligned stowed position above the vehicle and an operative position within the watercraft and below the vehicle. Hydrofoils may be connected to the water propulsion system, and bow or transom flaps plus the planing hull of the vehicle aids in providing adequate lift when in the water.
