Our V15 Deck Cover is made with breathable Top Gun polyester fabric. Use with the mast completely off the boat. 1/4 shock cord in the hem exits at the rear of the cover. The new style cover has built-in webbing cross-straps with adjustable, quick release buckles for a tight fit every time. This is the easiest and most secure cover attachment system available. Color: Gray (blue or aqua 2-3 week special order).
