Polyform F-Series Fenders

Polyform fenders should be inflated to:

• 0.15–0.20 bar at 20°C

Avoid over-inflation, as this can reduce shock absorption. Proper inflation ensures the fender can compress and absorb impact effectively, protecting your boat.

Polyform Norway fenders are industry-leading boat fenders manufactured using high-quality marine-grade vinyl and over 60 years of engineering expertise. Known for their even wall thickness, reinforced rope holds, and long-lasting durability, they provide superior protection compared to cheaper alternatives—making them a trusted choice for both leisure and commercial vessels.

Choosing the correct size depends on your boat length:

• 17–24ft boats → F1 or F2
• 25–30ft boats → F3
• 30–40ft boats → F4–F5

As a rule, larger fenders provide better impact absorption and protection, especially in tidal UK marinas. If in doubt, it’s always better to size up for added safety.

Most boats require at least 3–4 fenders per side when mooring. For larger vessels or exposed marinas, you may need more. Proper spacing ensures consistent hull protection and reduces the risk of damage in changing conditions.

Polyform fenders outperform budget options due to:

• Consistent wall thickness (prevents weak points)
• Reinforced rope holds (reduces failure risk)
• High-gloss finish (protects your boat’s appearance)
• Proven longevity (trusted worldwide for decades)

Cheaper fenders often fail under pressure, risking costly hull damage—making Polyform a smarter long-term investment.

Yes—Polyform F-Series fenders are ideal for:

• Mooring alongside pontoons
• Rafting with other boats
• General docking protection

Their cylindrical shape provides maximum contact coverage and stability.

• F-Series → Larger boats, heavier-duty protection
• G-Series → Smaller boats, lighter applications

F-Series fenders are designed for greater displacement vessels and harsher conditions, offering increased protection where it matters most.
