A fin stabilizer is provided for a vessel and includes a fin which is supported by a shaft that extends below the waterline. The shaft is fixed in rotation along its elongate axis relative to the vessel and the fin includes an actuator mechanism which causes the fin to rotate around the shaft to counteract roll of the vessel. In some cases, the actuator may be hydraulic and the shaft may include passages therethrough to transfer hydraulic fluid/pressure from the vessel's interior hydraulic system through the shaft and into the actuator to cause the fin to rotate. The fin may also be able to pivot into a storage position where, for example, the shaft is folded into a cavity in the vessel hull.
