<p>An outboard surface operation auxiliary device capable of assisting the operation from the inside of a hull by using an operation port allowing the inside of the hull to communicate with the outside thereof, comprising an insert port formed of an elastic member closely fitted to the periphery of the arm of a worker passed from the outside through an inner space formed of a waterproof surface layer in a device body and a sealing port engaged sealably with the operation port and allowing the operation port to communicate with the internal space, whereby, since the interior of the device body is cut out from the inside of the hull when the arm is inserted from the insert port after the sealing port is engaged with the operating port, the operation on the outside of the hull can be performed on the inside thereof without leaking seawater into the hull.</p> |
