The present invention relates to a rudder for a vessel with a sub rudder enabling a vessel to sail efficiently and efficiently turning the vessel by adjusting a length of the sub rudder in accordance with the weight of the vessel. The rudder for the vessel with the sub rudder includes: an upper fixing plate (108) having an oval flange (104) with multiple connecting holes (102) on one side and an integrated pin shaft (106) on the lower part; a lower fixing plate (110) fitted into the other side of the pin shaft (106) and integrated with the pin shaft (106) by being welded while being spaced from the upper fixing plate (108); a body formed by covering the outer circumference of the connected upper fixing plate (108) and the lower fixing plate (110) by using a synthetic rein material, exposing the pin shaft (106) through the lower part, and filled with urethane to have buoyancy; the sub rudder (122) assembled with the top surface of the body (112), installed on one side of the top surface of the upper fixing plate (108) at a predetermined interval to the flange (104) to enable the length to be adjusted, and helping the sailing and the turning of the vessel when the vessel sails and turns; and a length adjusting means (124) installed on one side of the sub rudder (122) inside the sub rudder (122) and adjusting the length of the sub rudder (122) in accordance with the weight of the vessel. |
