A rail system for a pontoon boat is provided. The rail system allows for the addition and removal of a pontoon boat skin, as well as additional features and attachments without dismantling the rail system. The system may include detachable rail caps and/or rail attachments that hold the skin against the rail. The rails also include features to attach exterior attachments such as accents, bumpers, and inserts.

This invention is directed to a column floater with extended cylinder and a ring buoy-group, which comprises an upright buoy at a water surface, an extended cylinder, a positioning system and a topsides. The top of the upright buoy is above the water surface and a moonpool is either set or not in the center of the upright buoy through the top to the bottom. The extended cylinder, connecting to the bottom of the upright buoy and extending downwards, includes two types of fixed and sliding to form a column floater with fixed extended cylinder and a column floater with sliding extended cylinder respectively. The positioning system is one or two combined of mooring system and DP system. The column floater with extended cylinder is a new type floating platform with multi-purpose, combining advantages of the spar platform and the current cylindrical FPSO, high performance, safety and reliability.

An alignment guide for a pontoon boat lift that includes a pair of laterally spaced rails, where the spacing corresponds to the spacing between the pontoon floats. The rails are attached to the boat lift by adjustable brackets, so they are positioned at an elevation above the waterline of the pontoon floats, and below the deck that is supported by the floats. A stop bar is positioned at an elevation above the boat motor and extends between rail extensions that are directed downwardly and rearwardly from the spaced rails.

A stop bar is positioned at an elevation above the boat motor and extends between rail extensions that are directed downwardly and rearwardly from the spaced rails. The alignment guide functions to provide support under the deck of the pontoon boat, to limit movement of the craft from port and starboard, and to stop the craft when it has advanced to the full forward position to keep it properly positioned bow to stern.
