OWS Sail car, HA 91/A 009, Isomat, Briand, Sparcraft, Z-Spar

OWS (Outer Wheel slider) is an excellent upgrade from traditional sail slides to reduce friction when hoisting and dousing the main sail.
The depth and the shape of the slug is designed to correspond to sail slide HA 91 from Holt Allen and A 009 from Bainbridge. The four wheels roll on the aft side of the mast section while the slug slides inside the luff groove.
