    Patent number: 5195767
    Abstract: An adjustable boat trailer guide rail assembly includes a pair of transverse slide assemblies, a pair of upright slide assemblies and a longitudinal guide assembly. A pair of guide rail assemblies are mounted to a boat support chassis to simplify the loading and unloading of boats to and from boat trailers. The guide rail assemblies are adjustable in generally transverse, upright and longitudinal directions relative to the boat trailer chassis to ease the frequently difficult task of loading a boat onto a trailer while standing on slippery surfaces, a task frequently complicated by wind and turbulent waters.
