PROBLEM TO BE SOLVED: To minimize driving resistance, increase restoring moment, and provide good operability and stable navigation on either moderate or rough ocean, by providing hull volume and its practical volume above water surface, and by providing a float means which is formed by combining an upper anti-rolling float with the hull. SOLUTION: A ship has a hull 1 and a combination of at least two truncated- cone-shaped floats 2 which are upside down and are related to the hull 1 with an anti-rolling means 3, its upper foundation is fixed to inside of the hull 1, and its lower foundation is fixed to the upper part of the floats 2. The front end 7 and back end 6 of the anti-rolling means 3 have both ends to which taper specifying steep both edges 8, 9 which have hydrodynamic configuration is added so as to easily remove water. Total volume of the float is determined so that the float can support the hull 1 and load above water surface. |
