Abstract

PURPOSE: To make the flow of stream lines uniform and reduce navigation resistance by about 4% to 11% by providing a projection type spherical substance having length of 1/500 of the overall length of a ship or more in such a way that 50% of the side area or more is positioned above the waterline. CONSTITUTION: A spherical projection section is projected at least 1/500 of the overall length of the hull in length (a) from the bow, and the cross section area and volume of the projection section positioning above the waterline L is made 50% or more of the total section area and volume of the spherical projection section. In such constitution, the spherical substance above the waterline L reduces the disturbance of sea water and equalizes the flow of stream lines, resulting in the reduction of the resistance of the hull. Thus, the navigation resistance of the ship can be reduced by about 4% to 11% than that in conventional spherical bows, and fuel can be saved.
