Polyform F4 Marine Fender / Cylindrical Heavy-Duty Boat & Yacht Fender / Medium-Impact Hull Protection – Model F4 – Volume 35 Litres 🔹 Product Description 

• The Polyform F4 Fender is a mid-size heavy-duty cylindrical fender from the world-renowned Polyform F-Series, a flagship line of marine fenders trusted by seafarers, navies, and yacht owners for over 60 years.

• Built with POLYMATIQ™ technology—Polyform’s patented in-house rotational molding innovation—the F4 offers maximum structural strength, uniform wall thickness, and superior flexibility in any sea condition.

• Its seamless marine-grade vinyl construction provides high resistance against UV degradation, seawater corrosion, repeated impact, and harsh marine environments, ensuring long-term performance without cracking or fatigue.

• With an internal volume of 35 litres, the F4 provides substantial shock absorption capacity ideal for medium-sized vessels, reducing the risk of hull damage during docking, rafting, or portside operations.

• The fender’s dimensions (1040 mm length and 220 mm diameter) provide a slim, elongated buffer zone that distributes pressure evenly along the hull, especially beneficial for boats that require consistent side coverage.

• The reinforced ropeholds at both ends, molded as an integral part of the fender, feature multiple strengthening ribs, offering exceptional tensile strength and anchoring security during intense berthing conditions.

• The 28 mm eye diameter is designed to handle standard marine ropes, carabiners, or shackles for versatile horizontal or vertical installation, depending on the docking or hull structure.

• Weighing 2.90 kg, the F4 remains lightweight and easy to handle for marina staff, vessel crew, or yacht owners, even when multiple fenders are in use.

• The fender is pressure-rated at 0.15–0.20 bar at 20°C, providing optimal inflation levels to maintain its protective capacity without risking rupture or over-expansion.

• The F4 is temperature-tested from -30°C to +60°C, making it suitable for extreme weather conditions ranging from icy waters to tropical heat, without compromising strength or elasticity.

• Commonly used across yacht clubs, coast guard vessels, commercial docks, and marina operations, the F4 fender is a highly versatile model suitable for daily use and long-term mooring scenarios.

• Its smooth, high-gloss finish is non-marking, protecting both painted hulls and delicate gel coats, and is easy to clean and maintain with soap and water.

• Ideal for vessels in the 8–14 meter range, this fender offers professional-grade protection in a manageable size that doesn’t compromise safety or visual appeal.

• It is also widely deployed by fishing fleets, patrol boats, diving vessels, and commercial service boats, where robust hull cushioning is essential during vessel-to-vessel or ship-to-dock contact.

• Like all Polyform products, the F4 is built to DNV-compliant standards and delivers ISO-grade consistency, reflecting its widespread acceptance across professional marine industries worldwide.
