Patent ID: 7311058

Claim:
A trim tab control system adapted to control left and right trim tabs on a water vessel, the trim tabs adapted to actuate up or down and the water vessel having a longitudinal and lateral axis and a helm with a trim tab control module, the trim tab control system comprising: a) a microcontroller having a plurality of data input lines and output lines, b) a control circuit adapted to actuate the left or right trim tabs, the control circuit in communication with at least one of the output lines of the microprocessor, c) a tilt sensor adapted to determine the amount of tilt about a longitudinal axis of the water vessel, d) a velocity sensor comprising a GPS unit adapted to transmit signals to a data input line of the microcontroller representing a measured velocity of the water vessel, e) whereas the microcontroller having logic to condition the signal received from the velocity sensor to determine an actionable velocity value is compared to a previously recorded actionable velocity value, where if the actionable velocity value is greater than the previously recorded actionable velocity value, the trim tabs are actuated in the same direction as the previously set direction; alternatively, if the actionable velocity value is less than the previously recorded actionable velocity value, the trim tabs actuate in the opposite direction than the previous trim tab adjustment direction, where the position of the trim tabs are monitored by the microcontroller from the power line which activates the trim tabs when the trim tabs are repositioned at the trim tab control module.
