Abstract
PURPOSE: To prevent propelling performance from deteriorating in sailing, by providing watertight sections in the water level parts of struts which couple an upper hull with lower hulls and by providing the walls of the sections with downward openings for connecting the interior of the sections with their exterior.
CONSTITUTION: A catamaran ship comprises an upper hull 1, a right and a left struts 2, 3 and a right and a left lower hulls (bodies) 4, 5. An appropriate number (for example, three) of watertight sections 6W8 are provided in the water level parts A of the struts 2, 3 so that the sections extend within the vertical motion of waves in the vertical direction and have an appropriate size and shape in the longitudinal direction. The sections have an appropriate spacing and locations. The inner and outer walls 6aW8a, 6bW8b of the sections 6W8 are provided with numerous openings 9, which serve to connect the interior of the sections to the external air or ambient sea water and which extend downward from the inside of the sections toward their outside. Air vents 10 are provided through the upper part of each section wall.
