Master Fender Covers A4 - 21-1/2" x 28" - Double Layer - Navy

The Master Fender Covers A4 – 21-1/2" x 28" – Double Layer – Navy is purpose-built marine protection gear designed for vessel owners and professional boat operators who demand reliable hull and topsides defense. Whether you maintain a recreational cruiser, commercial workboat, or tactical watercraft, these covers prevent costly gel coat damage, oxidation, and fender scuff marks that accumulate during regular docking and mooring operations. Built for active use rather than storage, the A4 model fits standard medium to large fender applications and is ideal for anyone seeking affordable, long-term hull preservation.

The double-layer construction sets these covers apart from single-ply alternatives, delivering enhanced durability while maintaining a soft, non-abrasive surface that won't scratch or damage your boat's finish. The reversible design extends service life by allowing rotation based on wear patterns, and the navy colorway offers professional aesthetics that blend with most vessel schemes. At 21-1/2 inches by 28 inches, the A4 dimensions accommodate typical cylindrical and barrel-style fenders used across recreational and commercial fleets. The lightweight 1.8-pound profile makes installation, removal, and seasonal storage straightforward, with no special hardware or tools required.

These covers benefit boatyard professionals, charter operators, and individual vessel owners who prioritize preventative maintenance over reactive repair costs. Real-world application shows measurable return on investment within a single season—especially for boats docked in high-traffic marinas where fender contact is frequent and unavoidable. The A4 size works with standard rope-and-fender rigs and mounting systems, requiring only that your existing fenders fall within the stated coverage dimensions. Installation involves sliding the cover over the fender body; no modifications to existing rigging or deck hardware are necessary.
