Abstract: A retractable mooring line device comprising a reel for storing and paying off a mooring line (2), having side walls (22, 24) each comprising a series of notches (60) for receiving a releasable latch (54). A latch simultaneously engages between notches in both side walls (22, 24) at a substantially right angle to provide a secure, positive locking engagement between the latch and the reel while permitting the latch (54) to be released under the application of relatively little force. In the preferred embodiment the latch may be actuated by a user's hand or foot and is biased toward the reel by a spring (70) which bears against the housing (18). The mechanism can be exposed for maintenance or repair simply by removal of the gunnel plate (16) and reinstallation of the gunnel plate does not require special loading of the latch spring.

Abstract: A retractable boat line for mooring a boat is wound about a payoff reel contained within a stationary housing, which my be mounted beneath the exterior surfaces of the boat, for example within the hull, transom or gunnel. The invention provides a locking mechanism that latches into a guide wall of the payoff reel at a point remote from the edges of the guide wall to rotationally lock the payoff reel relative to the housing. The mooring line can thus be selectively extended to a desired length and remains locked to the selected length until the locking mechanism is disengaged.
