Abstract
A boat mooring arrangement which permits the boat to rise and drop vertically with tides or wave action, but which constrains the boat from lateral movement relative to a fixed dock or pier. A pair of cylindrical posts are affixed to the dock or pier at spaced-apart locations and extend vertically downward therefrom for a predetermined distance below the surface of the water. Associated with each of these posts is a carriage assembly comprising a U-shaped collar having rollers journaled for rotation across the spaced-apart legs of the U-shaped collar. The carriage assemblies cooperate with the exterior surface of the posts and ride up and down with respect to the posts when the carriage assemblies are fastened to the boat to be moored by suitable tie lines and changes in water level are encountered.
