This cover works well for both trailering and mast-up mooring. Reinforced cutouts with YKK® buckle closures at stays and wraparound mast collar with draw cord closures ensure a snug fit. Webbing loop(s) let you tent the cover by tying it to the boom. A durable UV-resistant polyester zipper runs from the mast to the sidestay or forestay, allowing easy on and off. Cover does not go over the boom.
