Abstract
A system is provided and includes a trim tab, a hinge assembly, an actuator, and a controller. The trim tab adjusts at least one of pitch, roll or yaw motion of a marine vessel while the trim tab is in a deployed state. The trim tab includes a member, which has first and second ends and curves outward between and forward of the first end and the second end in a direction away from a point rearward of the member. The hinge assembly attaches a rearmost end of the first trim tab to the marine vessel at a location rearward of the member. The member rotates about a portion of the hinge assembly. The actuator actuates the trim tab. The controller controls the actuator to transition the member of the trim tab between a retracted state and the deployed state to adjust an attitude or motion of the marine vessel.
