Original Polyform F5 Boat Fender – Maximum Protection for the Large Vessels
The Polyform Norway F5 Fender is the largest and most powerful model in the globally respected Polyform F-Series, a range regarded as the industry benchmark for professional-grade inflatable boat fenders. Designed for constant use in busy marinas, commercial harbours, and rafting situations, the F5 is best suited for vessels approximately 31-45ft (9.5-13.5m), including midsized superyachts, expedition yachts, heavy-displacement vessels, and wide-beam catamarans.
Built in Norway for Extreme Strength and Reliability
Manufactured from premium, marine-spec PVC, the F5 Fender is engineered to withstand harsh saltwater conditions, repeated heavy impacts, and prolonged UV exposure. Its one-piece seamless construction eliminates weak points found in welded alternatives, significantly reducing the risk of splitting, tearing, or air loss over time. This makes the F5 the preferred choice of captains, marinas, and professional marine operators.
Classic Smooth Cylindrical Profile
Unlike ribbed designs, the Polyform F5 features a smooth, traditional cylindrical shape, allowing for easy positioning along the hull and precise adjustment when mooring or rafting alongside other large vessels. This universal design is fully compatible with all high-strength fender lines, heavy-duty fender clips, and professional hanging systems, making it simple to integrate with existing deck setups.
Reliable Valve System & Efficient Inflation
The F5 Fender is fitted with a high-quality, secure inflation valve that ensures consistent air retention under extreme loads. It can be inflated efficiently using a high-capacity pump or compressor and maintains pressure reliably, reducing the need for frequent top-ups — essential for large vessels where maintenance efficiency is critical.

Recommended Accessories
For enhanced protection and a professional finish, the F5 Fender can be paired with a heavy-duty fender cover, which helps prevent scuff marks, hull staining, and surface wear while extending the life of the fender.
