Propulsive performance for a ship is improved by effective use of flows generated in rear of skegs when the ship is propelled. A biaxial stern catamaran ship (1) provided with two propellers is provided with propelling means (210, 220) which propel the biaxial stern catamaran ship by driving the two propellers and the two skegs (11, 12) which are provided at the body of the biaxial stern catamaran ship. The centers of the drive shafts of the two propellers are respectively positioned with offset from the center axes of the two skegs. Each of the skegs is twisted in an S-shape so as to change the flow naturally generated toward the rear of the skegs while the ship sails into a rotational flow, and a lot of the generated rotational flows are caught as a counter flow by the blade surface of the propeller positioned at an optimal position.
