PROBLEM TO BE SOLVED: To provide a small planing boat allowing easy cleaning inside a cooling passage of an engine or an auxiliary machine after traveling. SOLUTION: In the small planing boat, the engine E is arranged in a boat body A surrounded by a hull H and a deck D covering the upper part thereof and at least a part of the engine or the auxiliary machine is directly cooled by water at the outside the boat. One coupling member 34 of a pair of coupling members 34, 35 constituting a general purpose liquid connection coupler 32 is attached such that the other coupling member 35 can be coupled to an end at the coupling side so as to be communicated with the engine or the auxiliary machine constituted so as to be directly cooled by water at the outside the vessel. An opening 36 of the end at the coupling side of one coupling member 34 is closed by a lid member 38 so as to be openable and closable. COPYRIGHT: (C)2004,JPO&NCIPI
