This cover is an excellent addition to your Flying Scot, because it's so quick and easy. Also, it covers the mainsail, so you can leave it on the boom. Simply throw the cover over the boom, tie and fasten it down the mast. Finally, stretch the 12 rubber hooks on bungee to the deck to keep the cover on in seemingly all conditions. This cover does a wonderful job of keeping the water out, and again, it's so easy to put on!
