  • Reinforced ropeholds secure lines for long-term mooring reliability
  • Even wall thickness ensures maximum durability under pressure

Cobalt Blue Twin-Eye Fender

The POLYFORM G-2 Twin Eye Fender in Cobalt Blue measures 4.5" x 15.5" and is built for boats between 10' and 20'. Even wall thickness and moulded-in ribs deliver consistent strength and abrasion resistance. Reinforced ropeholds and a unique Polyform valve support long-term durability in marine conditions.

Suits trailered boats and protected moorings

This fender is designed for vessels in the 10' to 20' range that operate from trailers or sit in sheltered permanent moorings. Boats outside that length bracket or craft exposed to heavy open-water swell should look at alternative protection.

Integrates with standard mooring lines

Reinforced ropeholds accept common dock lines so the fender secures quickly to cleats or rails. The integrated valve allows straightforward inflation adjustments without special tools. Its compact profile leaves deck space clear while maintaining a protective buffer against dock contact.

Questions about this item

What boat length is the 4.5" x 15.5" fender rated to protect?

The fender is designed for boats measuring 10 to 20 feet in length, making it suitable for trailered craft and permanent protected moorings.

Will the reinforced ropeholds accept the same lines I use on older cylindrical fenders?

Yes, the moulded reinforced ropeholds are sized for standard marine dock lines, so existing ropes can be used without modification.

How can I confirm the even wall thickness is holding pressure after inflation?

Press the ribbed surface; it should feel uniformly firm with no soft spots, and the unique Polyform valve should retain air without leaking over time.
