Polyform F-11 Twin Eye Fender 21.2" x 57.5" - White

The Polyform F-11 Twin Eye Fender 21.2" x 57.5" in white is the marine industry's gold standard for hull protection, trusted by commercial fishing fleets, charter captains, and serious recreational boaters for over 50 years. Whether you're docking at a crowded marina, rafting alongside another vessel, or navigating tight channels, this full-size fender absorbs shock and prevents costly damage to your boat's topsides. Available for sale with proven reliability across every boating condition, the F-11 is engineered for vessels that demand genuine protection without compromise.

Constructed from marine-grade elastomer, the F-11 features twin eye design that secures easily to cleats, rails, or fender lines using standard rope or hardware. The substantial 26-pound weight and 21.2" diameter profile provide exceptional load distribution, making contact with pilings, dock edges, and other vessels far more forgiving than lighter alternatives. White UV-resistant construction maintains appearance and integrity through years of saltwater and freshwater exposure, while the tapered cylindrical shape protects extended hull sections effectively. Polyform's F Series engineering ensures consistent performance in both calm anchorages and choppy coastal conditions where deflection and energy absorption matter most.

This 57.5" length suits vessels from 35 to 65 feet, making it ideal for cruising sailboats, commercial fishing boats, and cabin cruisers where a single large fender outperforms multiple smaller units. The twin eyes accommodate various rigging approaches—vertical hanging from a single point, horizontal raft configuration, or permanent installation on fender boards. Installation is straightforward for any boater comfortable with basic line work; no specialized tools required. Specifications show weight of 26 lbs and overall dimensions supporting professional-grade dock and anchorage use where reliability directly impacts safety and resale value.
