A basic version of the custom and styled to fit boat covers, Flex-fit covers are made using the same high quality materials as the other styles of boat covers, but are made for a loose fit - think of it as a slipcover for your boat. These are one-size-fits-most covers which are suited for a wide range of boats and are available in either vinyl or 2-ply weatherproof fabric.There are also specialty covers. These are made for boats with features which ordinary marine boat upholstery cannot accommodate such as T-towers and ski towers. These boat covers include long tower slots to protect these towers, with hook and loop closures and reinforcement to provide reliable protection for your ski boat or deck boat's tower.Tournament boats, V-hulls and boats with T-towers call for special covers which fit these different styles. Each of these covers are made with 8 oz performance poly guard, double reinforced bow areas to accommodate anchor rollers and bow pulpits and double zippered port and starboard entry for access. These boat covers include a heavy duty boat cover tie down kit, a self-adhesive boat cover reinforcement kit, two support poles and a rope ratchet.A boat with a Custom Cover has the ability to weather the off-season through winter's snow ice and temperature variations and through storage, mold and other conditions and trailering. High quality marine boat upholstery outlasts time to keep your boat in tiptop shape through storage and ready for the next water outing.
