Abstract
An apparatus positions a boat having a clip attached to a bow onto a boat trailer. The apparatus is used with a winch and two guides mounted on the boat trailer. The two guides are positioned a selected distance from the winch toward the rear of the boat trailer and spaced apart from each other. The apparatus includes three line sections windable about a reel of the winch with two of the line sections being windable about the reel in one direction and the third line being wound in an opposite direction. The two lines that are wound on the reel in the same direction extend around the guides while the third line extends between the guides and all of the lines being connected to each other at their distal ends. Forward movement of the boat engages the clip with the lines such that the boat can be winched onto the trailer.
