This full-deck, mast-up sailboat cover fits securely over the boom. There are heavy-duty zippered cutouts for the backstay, sidestay, and forestay. Heavy-duty zippers on both sides of the mast allow easy on and off. Vents between the mast and forestay and at the transom circulate air to minimize condensation. Web tabs with grommets for tie-downs on port and starboard sides fasten the cover securely. A 24 in. skirt protects the sides of the boat.
