Polyform G-4 Twin Eye Fender 6.5" x 22" - Blue w/Adapter

The Polyform G-4 Twin Eye Fender 6.5" x 22" in Blue with Adapter is the marine industry standard for protecting your hull during docking, rafting, and mooring operations. Built by Polyform U.S.—a name trusted by commercial operators, yacht clubs, and serious recreational boaters for over 50 years—this fender absorbs impact energy that would otherwise transfer directly to your boat's gelcoat, topsides, and rubbing strakes. Whether you're navigating crowded marinas, tying alongside a seawall, or raft-ups with other vessels, this twin-eye design distributes fender placement flexibility while maintaining maximum protection in the zones where damage most often occurs.

The G-4 features Polyform's proven UV-resistant polyethylene construction, engineered to withstand extended sun exposure without degrading or losing compression resilience. At 6.5 inches in diameter and 22 inches in length, this size delivers optimal protection for boats ranging from 28 to 45 feet, with sufficient mass (2.6 lbs) to absorb moderate to high-impact loading without bottoming out against the hull. The twin-eye configuration—with both upper and lower eyes—provides dual attachment points, allowing you to customize fender orientation and spacing to suit varying dock and marina conditions. The included adapter ensures seamless integration with standard fender lines and bridles, eliminating compatibility guesswork during installation.

This fender is ideal for boaters who regularly operate in high-traffic anchorages, narrow slips, or rough water where contact with pilings, jetties, and neighboring hulls is frequent. Cruisers, charter operators, and marina liveaboards rely on G-4 fenders in sets of two or more to create comprehensive side protection. The blue color is highly visible, reducing nighttime snag risks and serving as a visual aid during tight docking maneuvers. Installation is straightforward: simply thread your fender line through the dual eyes, adjust height to match your boat's rubbing strake, and secure to your existing deck cleats or rail mounted hardware. Replacement is easy when wear eventually occurs, making the G-4 a cost-effective long-term investment in hull protection.
