Abstract

PURPOSE:To ease inflow and outflow of sea water into life retaining holds in such a way that inner cylinders which provide water passing holes at the bottom planes are stuffed into the inside of life retaining plugs, and the inner cylinders are available for protruding or inserting at the level of the ship's bottom. CONSTITUTION:It is integrated in such a way that life retaining plugs 12 are installed in the number of about thirty pieces on th ship's bottom of the life retaining holds on board the fishing boat, holes are made on the bottom board 13 of the ship's bottom for the purpose of the life retaining plugs 12, flange rings 7 are embedded into the outer face, cylindrical bodies 2 are inserted from the inner face, flanges 3 of the cylindrical bodies 2 are tucked into the inside of the bottom board 13, and inner cylindrical bodies 8 are stuffed into the cylindrical bodies 2, when navigating the hull, flow pressure is increased by sea water current, suction negative pressure is generated in water passing holes 9, and sea water in the life retaining holds can be flowed out, and if the cylindrical bodies 8 are stuffed so as to be put inward to the cylindrical bodies 2, sea water can be conversely flowed through the water passing holes 9 into the life retaining holds.
