Polyform Cylindrical F Series Boat Yacht Fender F7 Banana Fender

Polyform F7 Cylindrical Marine Fender / Heavy-Duty Fender for Large Boats-+
& Yachts / High-Impact Hull Protection – Model F7 – Volume 85 Litres �� Product Description 

• The Polyform F7 Fender is a large-capacity heavy-duty cylindrical fender designed for superior performance in high-impact berthing, ship-to-ship transfers, and commercial docking environments.

• Manufactured with Polyform’s proprietary POLYMATIQ™ rotational molding technology, the F7 delivers uniform wall thickness, consistent material strength, and long-lasting flexibility even under intensive marine conditions.

• Made from marine-grade, UV-resistant vinyl, the F7 resists wear caused by constant exposure to seawater, salt spray, sunlight, and physical contact—ensuring high resilience and performance longevity.

• With a massive volume of 85 litres, the F7 is engineered to absorb considerable kinetic energy, protecting larger vessels during high-stress operations like tug assists, fishing port landings, or offshore platform docking.

• Measuring 1020 mm in length and 375 mm in diameter, it offers broad surface contact with dock walls or neighboring hulls, allowing for better pressure distribution and impact deflection.

• The fender is equipped with two heavy-duty ropeholds, each reinforced with multiple strengthening ribs, enabling secure vertical or horizontal mounting without the risk of eye failure under tension.

• The 28 mm eye diameter provides compatibility with a wide range of marine rigging options, including heavy-duty ropes, mooring cleats, stainless shackles, or chain lashing systems.

• Despite its size and performance, the fender weighs only 5.30 kg, enabling manageable deployment by two crew members or even a single person with a hook or fender basket.

• The fender must be inflated to a pressure of 0.15–0.20 bar at 20°C, as over-inflation can reduce product lifespan or compromise its internal structure—critical for vessel safety and performance assurance.

• It has been laboratory-tested to function in extreme temperatures ranging from -30°C to +60°C, making it ideal for commercial or naval operations in both cold-weather ports and tropical marine zones.

• The F7 is extensively used by naval ships, coast guard patrol craft, tugboats, offshore barges, pilot boats, and commercial yachts, thanks to its unmatched combination of durability, flexibility, and energy absorption.

• Its smooth, glossy, and non-marking surface helps prevent scratches or marks on gel coats and painted hulls, while its wide body provides protection against hull abrasion and structural contact damage.

• Particularly suited for vessels in the 14–22 meter range, the F7 is ideal for long-term berthing, high-tide fluctuations, and rough sea conditions where hull contact may occur during swell or surge.

• The fender is maintenance-free, requiring only occasional cleaning with water and soap to remove salt buildup, algae, or dockside grime.

•  meeting DNV and ISO maritime compliance, the Polyform F7 stands among the most reliable professional-grade fenders available in global marine markets.

• Its design is suitable for both portside berthing and side-to-side vessel fendering, making it highly adaptable for multi-use marine environments, including cargo transport vessels and offshore service ships.
