<P>PROBLEM TO BE SOLVED: To provide a ship's bottom jacket structure capable of developing the effect of suppressing frictional resistance to water over the relatively long section of a ship's bottom and capable of avoiding the status of increasing the frictional resistance to water. <P>SOLUTION: The ship's bottom jacket structure includes a plurality of downward protruded plates 11 each having a downward protruded bent plate cross section curved or bent into a downward protruded shape and extending in the longitudinal direction of a ship, and continuously provided via connection parts 12 along the lower face of the ship's bottom B in the cross direction. The downward protruded plates 11 each have an air flow path 2 opening near the front end of the plate and extending between the plate upper face side and the ship's bottom B over in the longitudinal direction of the ship, and cut-out parts 4 formed by cutting out the plate cross section upward from its protruded lower part over the bottom part or both side parts of the plate to divide the air flow path 2 at a plurality of positions. <P>COPYRIGHT: (C)2012,JPO&INPIT |
