Abstract

PURPOSE: To prevent the fall of the actual waterline on the voyage to heighten propelling efficiency, by shaping the stern of the lower hull of a semisubmerged multibody boat with a propeller at its rear end so that the point of intersection of the top line of the longitudinal section of the stern with its bottom line is located above the center line.
CONSTITUTION: The stern of the lower hull 1 of a semisubmerged multibody boat having a propeller shaft 6 and a propeller 4 at the rear end is shaped so that the point P of intersection of the top line 1c of the longitudinal section of the stern with its bottom line 1d is located above the center line and the propeller shaft 6 is supported by a slug 7 secured along the bottom line 1d of the lower hull 1. As a result, the downward component of a water flow F' along the top line 1c is restricted, the upward component of another water flow F" along the bottom line 1d is increased, the fall Δh of the actual waterline La on the voyage is prevented and the propelling efficiency of the propeller 4 is heightened.
