The Easy-Uphaul allows a windsurfer to raise the sail effortlessly. You can lift the sail without using your hands. (See photo.) Simply put the loop at the end ot the Easy-Uphaul on your harness hook, and then lean back, the sail will rise out of the water. Then when the sail has risen part of the way above the water, simply grab the uphaul and finish by hand. When the mast is up, the Easy-Uphaul will fall off your harness hook by itself.
