Marina fenders—often called dock fenders—are protective barriers fitted to pontoons, marina berths, and dock edges to absorb impact from boats during mooring.  They act as an extra layer of protection if things do not quite go to plan!

Polyform fenders are:

• Made in Norway using high-grade marine polyethylene
• UV-resistant and built for long-term outdoor exposure
• Designed for heavy-duty, repeated impact
• Trusted globally in commercial and leisure marinas

Cheaper fenders often:

• Crack under pressure
• Degrade in UV
• Require frequent replacement

Polyform MF and MBF fenders are designed for bolt-through installation onto:

• Wooden pontoons
• Concrete dock walls
• Steel or aluminium structures

They feature pre-moulded fixing points for straightforward mounting.

Yes—installation is straightforward if you have basic tools. However:

• For large installations or commercial marinas, professional fitting is recommended
• Correct spacing and alignment are critical for effective protection

Spacing depends on boat size and usage:

• Typically no more than 1–1.5 metres apart
• High-traffic or commercial docks may require tighter spacing

The goal is continuous protection—no gaps where hull contact can occur.

• MF Series (Marina Fender): Flat-backed design for mounting directly onto docks or vertical surfaces. Ideal for standard marina berths and pontoon edges.
• MBF Series (Marina Bow Fender): Rounded profile designed to protect bow sections or exposed corners where impact angles vary.

In simple terms:
MF = straight edges
MBF = corners and bow contact points

Sizing depends on:

• Vessel size and displacement
• Berth type (private pontoon vs commercial marina)
• Exposure (calm marina vs tidal/current conditions)

As a rule of thumb:

• Small leisure boats (up to ~8m): MF44 dock fender
• Mid-size boats (8–12m): Medium MF60 dock fender or MBF
• Commercial / high traffic: Larger, heavy-duty units – MBF150 dock fender

If in doubt, oversizing is always safer—under-spec fenders fail faster and offer less protection.

Yes—Polyform MF and MBF fenders are widely used in:

• Commercial marinas
• Harbours and ports
• Ferry terminals
• Industrial marine environments

They are built for high-impact, high-frequency use.

No—when correctly installed, they protect the hull.
Polyform dock/marina fenders are designed to absorb impact without causing abrasion.
