Abstract

A mechanism with one foot pedal for controlling the fore-and-aft attitude of a high-speed boat having the usual cavitation or trim plate. When the foot pedal is depressed the cavitation plate is lowered through an interconnecting assembly of pivoted members to lower the bow of the boat against any upending tendency as it accelerates from a dead stop in the water. As the boat speed increases, release of pressure on the foot pedal causes movement of the cavitation plate to an upper position, wherein it is ineffective to lower the bow, and locking of the plate in that position until the foot pedal is again depressed.
