I. Technical Field
The present invention relates to twin-skeg ships having a pair of left and right skegs provided on the bottom of the stern so as to support propeller shafts.
II. Description of the Related Art
A twin-skeg ship having a pair of left and right propeller shafts supported by skegs integrated with the hull so as to form a tunnel-like bottom recess between the left and right skegs is known in the related art (see, for example, Japanese Unexamined Patent Application, Publication No. HEI-8-133172).
On the other hand, a reaction fin has been devised as a propulsion-performance improving unit installed in a ship to improve the propulsion performance of the ship (unit for improving the speed of the ship with the same horsepower) (see, for example, Japanese Unexamined Patent Application, Publication No. HEI-5-185986).
