This Viper 640 Mooring Cover from Masthead is designed to protect the entire deck of your boat with the mast up, using the boom and main halyard to create a tent that helps shed water from the cover. This is a great option for Viper owners looking for no-worries protection while their boat is on a trailer, lift or at a dock.
This cover is made with Top Gun Fabric, an acrylic-coated texturized woven polyester. Its multi-ply construction accounts for its unmatched wear-ability, toughness and abrasion resistance. Top Gun's coating will not harden, crack or peel in the widest range of heat and cold; it sheds water with incredible efficiency. Available in Gray.
