PURPOSE:To firmly assemble a catamaran and form the catamaran to a compact size in its storage when the catamaran is not used, by connecting floats constituted with a bag body, which holds a shape by filling air, through front and rear beams while connecting central parts of each beam and end parts of each beam on the floats through respective connection members. CONSTITUTION:A pair of floats 1 formed by a waterproof cloth material of rubber, plastic, etc. and constituted with a bag body holding its shape by filling air to the inside are connected to each other by front and rear beams 2, 3. Each end part of the beams 2, 3 is connected by the first connection members 40 arranged on the floats 1, while central parts of the beams 2, 3 are connected by the second connection member 4 through receiving parts 30. A mast 6 of a sail 5 is supported onto the second connection member 4. At assembling, a catamaran can be formed to firm construction by the beams 2, 3 and the connection members 4, 40. Each member can be disassembled, and the catamaran can be formed to compact the size when it is not used, then the catamaran can be easily stored and transported. |
