WindSUP - Making windsurfing easy again!
The WindSUP is all about making windsurfing simple again, without losing the advantage of modern technology. The sail can go from the roof of your car to the water in under a minute. Just pull the mast bag off, fold the boom down and roll the sail out. Attach the outhual and you're ready to go! With vertical battens, this sail can roll up on the mast, so it offers the convenience of keeping the sail on the mast but still maintains a modern outline with a fat head and increased area below the boom. Pop this on an SUP or any longboard and remember how fun windsurfing can be in 5 to 10 knots of wind. Construction: Durable dacron sail with vinyl window 2-pc composite mast (370 for 4.0>, 430 for 4.8<) Adjustable clamp-on boom Uphaul Base Storage bag fits over rolled up sail and allows you to keep your boom attached.
