Speed detecting device mounting structure for a vessel

摘要

To provide a speed detecting device mounting structure for a vessel in which a paddle is prevented from being entangled with rubbish and seaweed in the sea, and the paddle is prevented from being damaged or picking-up mud or the like from the sea bottom. In a vessel, a water jet pump is provided at a rear portion thereof. A ship bottom plate is provided below the water jet pump. A speed detecting device is mounted on the ship bottom plate. A paddle of the speed detecting device detects the flow rate of water flow and obtains the propelling speed of the vessel. The speed detecting device mounting structure for a vessel is constructed in such a manner that the paddle of the speed detecting device is disposed on the upper surface of the ship bottom plate, an opening is formed at the portion of the ship bottom plate forwardly of the speed detecting device, and water taken through the opening is guided to the speed detecting device.
