Sail slides

The OWS is a superb improvement over traditional sail sliders, reducing friction when hoisting and lowering the mainsail. It fits earlier models of Seldén mast sections as well as most other mast brands. Four rollers run along the stern side of the mast section, and the slider slides into a slot in the leech. The depth and shape of the track are designed for specific mast sections, and there are five different designs to choose from.
