Abstract
A marine vessel stabilizer and control including a fin having a stem extending into the hull. An arm is connected to the stem and extends towards a connector which is connected to a rod. A housing is connected to another end of the rod and a screw passes through the housing. A motor is connected to the screw and configured to rotate to rotate the fin. A controller is connected to the motor, a speed sensor, a roll sensor and a fin position sensor such that a control signal can be calculated and the position of the fin can be determined to reduce roll of the vessel both when making headway and when at rest (zero speed). When the vessel is at rest, the fin is be configured to rotate through maximum angles greater than 15 degrees from either side of a neutral position.
