ABSTRACT:
A pontoon boat loader to assist in the loading of a pontoon boat onto a trailer. The pontoon boat loader includes a pair of upwardly extending guide posts which may be pulled apart to engage the interior side of each pontoon in order to induce alignment of the boat with the trailer. Each guide post is carried by a slide mount which is received within a slide channel. The slide channel is mounted on a conventional pontoon boat trailer in a conventional manner. The two slide mounts are biased toward each other by way of a tension spring connected at each end to each of the slide mounts. In order to separate the two slide mounts, a cable is provided for each slide mount, with a first end of the cable being secured to the outboard end of the slide mount. The second end of both cables are then secured to each other. A winch is provided to facilitate engagement of the guide posts with the interior side of each pontoon. A winch cable is connected at its distal end to the second ends of the slide mount cables. As the winch is operated to coil the winch cable, the slide mount cables are drawn toward the front of the trailer, thus pulling the slide mounts and guide posts apart. The guide posts are provided with a stationary hub mounted on the slide mounts and a sleeve loosely received over the hub such that the sleeve may freely rotate about the hub to enable free movement of the pontoon boat with respect to the guide post hub as the pontoon boat is engaged with the guide post sleeves and is drawn onto or launched from the trailer.
