A storage structure for a craft is mounted in a recess 1 which is disposed inside the ship 10 and at a safe distance from the water line of the ship 10 so as to store a craft 20. A guide rail 6a of a launching device 6 is installed on a deck 3 which is the ceiling plate of the recess 1 in such a manner that the guide rail is inclined downward toward the port 1a of the recess 1. At the gate 1a, a lower gate 13 and an upper gate 12 are installed. A winch 15 for opening/closing the lower gate 13 is mounted on the deck 3. The upper gate 12 is automatically opened by the movement of the craft 20 by gravity caused by the removal of a stop 6d. A winch 11 is mounted for the launching of the craft. 20.
A storage structure for one or more crafts in a marine structure including an upstanding side which extends downwardly from the storage structure to a normal water line, said storage structure including a recess inwardly of said side for containing said craft, said recess being openable and closable relative to said side above said water line by shiftable gate means, craft support means in said recess supporting said craft therefrom, mounting means in said recess for moving said craft therefrom, mounting means in said recess for moving said craft support means together with said crafts from a storing position wholly within said recess to a launching position outwardly of said recess and side, said craft support means including means for lowering and hoisting said craft between said launching position and said water line, said recess opening outwardly of said side through a port formed therein including upper, lower and opposite side margins, said gate means including upper and lower gates operatively associated with said port and movably supported from said side for movement between open and closed positions opening and closing, respectively, the upper and lower portions of said port, said upper gate being pivotally supported along an upper margin thereof from the upper margin of said port for swinging in a generally vertical plane for movement between the open and closed positions thereof with said upper gate being generally coextensive with said lower gate when both of said gates are in the closed positions thereof and said upper gate projecting generally horizontally outwardly of the upper marginal portion of said port when said upper gate is in the open position thereof with said craft support means maintaining said upper gate propped in the open position thereof when said craft support means is in said craft launching position, said lower gate being supported from said side for generally vertical guided movement between a lowered open position and a raised closed position.
