This Railblaza adjustable platform fits in the Railblaza StarPorts and in winches that are present on many sailing boats. The adjustable platforms can also serve as a flat surface for many on-board applications such as tables, barbecues, etc. When the platform is not in use it can be removed so that the StarPort can be used for another application. The platform comes with screw holes and more holes can easily be drilled allowing you to tilt items 180 degrees, in increments of 15 degrees.
