Abstract
Apparatus and a method for guiding objects such as boats in and out of slips. A pair of guide lines on opposite sides of the slip receive guide blocks for movement along the lengths of the guide lines. Each guide block has a pair of block portions movable toward each other to a first position for securing the boat line thereto and movable away from each other to a second position for releasing the boat line. A release line is anchored at one end and attached to each guide block at the other end to have slack during movement of the boat into and out of the slip. When slack in the release lines is taken up during movement of the boat out of the slip, tension applied to the guide block by the release line and the boat line moves the block portions to the second positions for releasing the boat lines.
