摘要： PROBLEM TO BE SOLVED: To provide a ship rudder for enhancing course keeping performance of a vessel by reducing rudder resistance during straight advancing of the vessel with an easy means as well as reducing meeting rudder resistance in a minute steering angle as much as possible by improvement of a lower end part of a conventional ship rudder provided with an inverted trapezoidal side shape.
SOLUTION: A rudder 2 provided for a stern 1 is equipped with an additive object 2b which is a flat spindle body having an airfoil vertical cross section slightly projecting outward on a lower end of a rudder body 2a having the inverted trapezoidal side shape. A center line 2c of the vertical cross section of the additive object 2b is inclined backward and obliquely upward, and the inclination angle α is set to be 4-10 degrees. The additive object 2b receives a stream to the rear part of a ship bottom part near the rudder during the navigation to generate lift. As the forward component act as thrust, the rudder resistance can be reduced, and augmentation of maneuvering force is expected at the time of steering.

摘要： PROBLEM TO BE SOLVED: To improve propelling performance of a ship by making effective use of a flow generated at the rear portion of a skeg during propelling of the ship.
SOLUTION: This two-axis catamaran type ship 1 equipped with two propellers includes propelling means 210, 220 of driving the two propellers and propelling the two-axis catamaran type ship and two skegs 11, 12 attached onto the a hull of the two-axis catamaran type ship. The centers of driving shafts of the two propellers are positioned to have offsets 2A, 2B, respectively, from center shafts of the two skegs. The skegs have such a twisted shape as to rotate and advance a naturally generated flow toward the rear portion of the skeg during navigation of the ship. The propellers located at an optimum position capture most of the generated rotating flows in a wing surface as a counterflow, thus enhancing a propulsive force of the ship.
