Abstract: It is common practice for pleasure boaters to moor their craft to fixed and buoyed moorings by securing a line from the vessel to a ring attachment on the mooring. To accomplish this normally requires one person standing at the bow to capture the ring on the mooring with a boat hook and lift the mooring ring sufficiently so that a line can be passed through the ring and secured to the boat. This procedure has to be performed from a height of one to three meters above the water and sometimes can be hazardous.With the present invention, the mooring procedure can be performed with increased safety and with a single action by utilizing a hook mechanism comprising a rigid body and a spring loaded detachable arm attached to a common extension pole and used to pass a line through a continuous ring and recovering said line. The rigid body has guided cavities incorporated at specific locations within the rigid body to receive the detachable arm.
