Opti WinDesign Mast Float

Works great! Fits easily around my sail in the mast channel for the mainsail. Wish it came in separate sizes because it was clear my sailboat didn't have a chance to turn turtle when half-way turned over. The float provides a lot of buoyancy with lots of leverage out at the top of the mast. The one I got is about two feet long and about six circular inches on each side of the sail. Not beautiful, but hey, you won't turtle your sailboat ever if you put this on your mast.

Great product
