Abstract

PURPOSE: To decrease friction resistance in the bottom surface of a ship and increase its lift, by filling exhaust from an engine partially in a groove-shaped bottom part formed along a keel line.
CONSTITUTION: Along a keel line l, a groove-shaped bottom 2 with a certain width is formed, and a wall 3 is provided in the farthermost part of the bottom 2. Then the wall 3 forms a step 5 on a ship bottom 4. A main exhaust pipe (b) of an engine (a) is opened in the before described groove-shaped bottom 2 and a part 6 filled with exhaust is provided in the bottom 2.
