Abstract
A watercraft trim system having port and starboard trim flaps which mount near the stern. The trim flaps are independently operated by pneumatic operators. The pneumatic operators are governed by pressure modulators which each advantageously include a gas compressor and controllable pressure relief valve. An automatic control system is used to control the pressure modulators. The control system includes attitude sensors using optical emitter-detectors which beam across liquid-filled channels. The channels contain gas bubbles which are detected by the emitter-detectors to indicate attitude deviations.
