  • Method of using pontoon trailer travel kit
    Patent number: 6663130
    Abstract: A pontoon trailer travel kit minimizes transverse spaces between a pontoon boat trailer and the pontoons of a pontoon boat. The kit comprises a bunk bracket that is mountable to and adjustable along a lift arm of the trailer. A bunk assembly is fastened to and is adjustable on the bunk bracket in directions perpendicular to the directions of adjustment of the bunk bracket. A kit is installed on a lift arm on each side of the trailer. The kits are pre-set such that the bunk of each bunk assembly is in close proximity to a pontoon. The boat is substantially prevented from sliding laterally on the trailer. In a modified embodiment, only the bunk assembly is used, and it is clamped directly to the trailer lift arm. That embodiment is used with boats in which the pontoons are exceptionally closely spaced to each other.
