Polyform F-4 Twin Eye Fender 8.5" x 40.5" - Blue

The Polyform F-4 Twin Eye Fender 8.5" x 40.5" in Blue is a professional-grade marine fender designed for serious boaters who require reliability both at the dock and while underway. This fender is particularly useful for navigating tight marina slips, rafting alongside larger vessels, or protecting your hull during extended anchoring. Its robust design ensures consistent performance in both freshwater and saltwater environments.

Constructed from closed-cell foam and durable vinyl, the Polyform F-4 resists water absorption and maintains buoyancy over years of service. This is critical when relying on it to absorb impact energy and protect your boat's expensive gelcoat or paint. The fender's 8.5-inch diameter provides substantial cushioning surface area without excessive bulk, while its 40.5-inch length spans the typical impact zone on most recreational and light commercial vessels.

Ideal for center console boats, cabin cruisers, and fishing vessels in the 24–40-foot range, the Polyform F-4's versatile design suits virtually any hull configuration requiring moderate-duty fendering. The twin eye design simplifies attachment to your existing fender lines or bridle system using standard rope. Additionally, the fender's neutral buoyancy ensures it won't sink or become an obstacle during use.
