This Attwood Deluxe Boat Cover Support System reliably elevates the boat cover in a strategic manner to prevent water from accumulating in the center of the cover. This easily adjustable boat cover support can extend the life of the cover by as much as 50 percent. It is intended for boats up to 19 feet. It features a telescoping center pole that can be adjusted from 28 inches to 48 inches in height. That pole combines with poly web straps and a bow spreader to form a double ridgeline under the cover. Water runs off the cover rather than pooling in a low center area. The 1-inch diameter aluminum pole rests on a rubber foot and the 1-inch wide black poly web straps attach to the stern using non-marring hooks.
