Abstract

A hydrofoil adapted for attachment to a boat propulsion unit.
The hydrofoil defines a recessed area on its underside in which a trolling plate may be positioned. A pivot shaft couples the plate to the hydrofoil permitting upright deployment of the plate for slowing of the watercraft. A locking bar on the hydrofoil serves to engage stops on the plate to lock same in retracted and de-ployed positions. A control permits remote operation of the locking bar.
