发明名称 Boat docking apparatus
摘要 A boat docking unit for small boats secures a boat to a dock structure without use of ropes, anchors or fenders. The unit has a pair of docking arms each having an elongated tubular housing, a telescoping member capable of telescoping movement within the housing. A pair of compression springs mounted in the housing in contact with the telescoping member dampens the wave force so as to restrict yaw of the boat docked at the pier. The docking arms pivotally secure the boat to the dock structure allowing a limited pitch motion of the boat.
