PROBLEM TO BE SOLVED: To collect even floating matters closely collected in a narrow place by providing a taking-in equipment to take in the floating matters between bodies of a catamaran hull, and providing a collecting equipment to collect the floating matters taken in between the bodies on the prescribed place. ;SOLUTION: Floating matters on the water surface are swept between bodies 4 by a sweeping equipment 5, and a conveyor 27 is driven to rotate a turbine 25 and generate the water flow W. When the floating matters 1 are loaded in a net basket by the conveyor 27, the floating matters 1 can be collected even in a non-navigable narrow water area, and each wind body 42 comprises split wind bodies 42A, 42B which are split into two parts in the ship breadth direction and deviated in the circumferential direction of the horizontal axis 41 by the prescribed angle when each wind body 42 is rotated. The split blade members 42A, 42B hit the water surface with the deviated timing, and the energy when the blade body 42 hit the water surface is halved, and components of the turbine 25 and their fitting parts are reduced in strength, and the amount of the water flow W is not reduced.;COPYRIGHT: (C)1997,JPO
