Polyform F13 Boat Fender

Polyform F13 Cylindrical Fender / Ultra Heavy-Duty Marine Fender for Large Ships & Offshore Structures / High Energy Absorption – Model F13 🔹 Product Description 

• The Polyform F13 Fender is the largest and most powerful model in the renowned F-Series from Polyform, specifically engineered for the most demanding marine applications including ship-to-dock, ship-to-ship, and offshore platform mooring.

• Developed using Polyform’s proprietary POLYMATIQ® rotational molding technology, the F13 features uniform wall thickness, a seamless vinyl body, and extraordinary mechanical strength – making it the global benchmark for ultra heavy-duty fendering.

• The fender is made from marine-grade, UV-resistant flexible vinyl that resists aging, cracking, saltwater erosion, and chemical exposure, ensuring long-term use in aggressive marine environments without compromising performance.

• Designed for extreme energy absorption, the F13 can handle up to 3.8 ton-meters (T·m) of impact force, making it suitable for ships up to 1500 DWT (deadweight tons) during mooring, cargo transfer, or harbor docking.

• Its extra-large cylindrical structure provides expansive surface contact, effectively distributing pressure across vessel hulls or dock walls to prevent structural damage during berthing or surge movement.

• The fender features two integrated ropeholds, each heavily rib-reinforced to resist breakage or deformation, and accepts extra-large ropes, chains, or hardware typically used in high-load marine rigging.

• Engineered for inflation between 0.15–0.20 bar at 20°C, the F13 offers the optimal balance of internal pressure and deflection, necessary for absorbing kinetic energy during vessel movement without risk of blowout.

• The F13’s size, weight, and volume (exact specifications to be provided) make it ideal for permanent dockside installations, especially in commercial ports, LNG terminals, naval shipyards, and industrial berths.

• Fully tested in temperature extremes from -30°C to +60°C, the F13 remains flexible and impact-absorbing whether used in Arctic operations or tropical equatorial zones.

• Its smooth, non-marking, high-gloss finish prevents damage or cosmetic scarring on high-value ship exteriors, superyachts, ferries, or defense vessels.

• The F13 is often deployed using cranes, davits, or hydraulic arms, and can be tethered horizontally or vertically using specialized mooring configurations based on vessel requirements.

• Trusted by port authorities, coast guards, navy fleets, tugboat operators, offshore contractors, and shipyards, this fender is an industry-standard where maximum hull protection is non-negotiable.

• The fender’s surface is easy to clean with standard freshwater or mild soap, and requires no ongoing maintenance, even during long-term use.

• Designed and manufactured, the F13 meets ISO and DNV compliance standards, making it eligible for government contracts, international port use, and regulated offshore deployments.

• With a massive production capacity of 10,000 units, the F13 is suitable for bulk tenders, fleet standardization, marina infrastructure upgrades, and multinational defense procurement projects.

• When unmatched durability, scale, and shock-absorbing power are required, the Polyform F13 stands as the ultimate choice in marine-grade cylindrical fenders.
