PURPOSE:To provide the subject vessel so designed that a fishnet washer with a specific scheme is mounted on the ship body and the marine organisms adhered to a large-sized fishnet are easily and rapidly washed away in high efficiency with high-pressure water in close proximity to the site where fishnets are placed. CONSTITUTION:Firstly, a supporting basal platform 49 in the ship body 40 is mounted with a startup source 2 and a large-capacity pump 3 and a water suction means 50 and a high-pressure water-conveying pipe 5 are connected to the suction port of the pump 3 and the delivery port of the pump, respectively. And, a jet nozzle 6 connected to the tip of the conveying pipe 5 is supported swingably in respective directions through a swing-supporting device S, thus making up the objective vessel. Second, this vessel is sailed to a site where fishnets X to be washed are placed and the pump 3 is actuated by startup of a driving source 2. Subsequently, seawater is put to suction by the water suction means 50 through the actuation of the pump 3 and conveyed as high-pressure water through the pipe 5 to the jet nozzle 6. Finally, the orientation of the jet nozzle 6 is set to the aimed direction with the swing-supporting device S and the high-pressure water is spouted from the jet nozzle 6 onto the fishnets X to be washed. |
