The invention relates to an intelligent sailing ship active stabilization device and a control method, a shaftless rim propulsion device is installed on a fin stabilizer close to the fin root, and the ship active stabilization device is controlled according to the rolling angle, the angular velocity information and the angular acceleration information collected by a ship attitude sensor and the ship navigational speed information obtained through a DGPS system. The rolling motion of the ship is reduced by controlling the fin angle of the fin stabilizer and the rotating speed of the shaftless rim propelling device to generate resistance moment. Different control methods can be adopted according to the navigational speed. When the ship speed is lower than a certain value, the lift force of the fin stabilizer is low, and ship rolling is reduced through thrust generated by the shaftless rim propeller; when the ship speed is higher than a certain value, the lift force of the fin stabilizer is high enough, and the
