Polyform Boat Fenders are made to protect your boat, even in tough conditions. When deciding on the size and number of fenders, plan for the unexpected and toughest weather conditions. Also consider extra Polyform Boat Fenders in addition to the "basic need".
Depending on the shape of the hull, weight of the boat etc, consider a possible mix of cylindrical ( F-Series / G-Series) and / or spherical (A-Series) Polyform Boat Fenders to achieve maximum protection.

Only the lower swivel (underwater) shall be used for mooring of the boat. The size of the buoy depends on the weight and the total load it will be exposed to. The dimension of the mooring iron bar and swivel should be chosen in accordance with the size and weight of the boat, weather conditions, the currents and wave height in the area the mooring is intended to be placed.
Do not expose the buoy to a load of more than 60% of its total buoyancy. Please also consider additional weight/load caused by marine growth, currents, wind, and waves.
Over-inflation will seriously weaken the material, destroy the products intended shape, reduce the lifespan of the product and void all warranty. Please remember to check your mooring for wear and tear at least twice a year. If in doubt, ask for professional advice.
The flexible all-plastic POLYFORM valve is fitted into every POLYFORM PRODUCT.
V10: During inflation, a flap at the lower end of the valve ensures little or no loss of air.
Securing the rigid plastic screw will then close the valve.
Valves (double valve system)
F11 (and optional F8) is equipped with the Provinor® Double Valve System (air in / air out). The valves are moulded into the rope-holds, located on opposite ends of the fender:
The clear plastic
inflation valve = AIR IN The blue coloured
deflation valve = AIR OUT
Polyform Norway F-series cylindrical fenders have set the standard for heavy duty fenders for close to 60 years. The newest generation are made by use of Polyform's unique, in-house developed and patented POLYMATIQ® technology.
Highest breaking strength is taken care of by the two multiple rib-reinforced rock solid ropeholds. Tested for strength and flexibility in temperatures ranging from -30oC to +50oC, these heavy duty fenders feature high abrasive resistance and high energy absorption (up to 3.8 ton meter for F-13), making them suitable for ships of up to 1500 ton d/w (F-13).
The Polyform F4 is ideal for boats up to 30ft (9m) long and available in the following colours:
- White with Navy Blue ropehold
- Navy with Navy Blue rope hold
