*Recommendations are general guidelines. Larger boats, rough docking conditions, or exposed moorings may benefit from using larger fenders.

Proper Fender Placement

For the best protection:

  • Tie fenders to a stanchion base, deck cleat, or secure rail.
  • Avoid hanging fenders from lifelines, as this can place unnecessary stress on the lifelines.
  • Position fenders so they just touch the water's surface when deployed.
  • Carry at least three fenders for most recreational boats, with larger vessels often requiring four or more.

Ideal For

  • Fishing boats
  • Aluminum boats
  • Sailboats
  • Cruisers
  • Pontoon boats
  • Yacht tenders
  • Marina docking
  • Permanent moorings
  • Trailered boats

Frequently Asked Questions

Q. What size Polyform G Series fender do I need?

The ideal Polyform G Series fender depends on your boat's length and docking conditions. Smaller boats typically use G-1 or G-2 fenders, while larger cruisers often require G-5 or G-6 models for maximum protection.

Q. Can Polyform G Series fenders be used in saltwater?

Yes. Polyform G Series fenders are manufactured from durable marine-grade vinyl designed for both freshwater and saltwater use.

Q. How many boat fenders should I carry?

Most recreational boats should carry at least three boat fenders. Larger boats or those docking in exposed areas often benefit from carrying four to six fenders.

Q. How should I hang a Polyform boat fender?

Attach the fender to a deck cleat, stanchion base, or secure rail using a fender line. Position it so the fender just touches the water and avoid hanging it from lifelines.

Q. What's the difference between a boat fender and a dock bumper?

A boat fender hangs from your boat to cushion impacts while docking. A dock bumper is permanently mounted to a dock or piling to protect both the dock and the boat.

Q. Are Polyform G Series fenders inflatable?

Yes. Polyform G Series fenders are inflatable marine fenders that provide excellent impact absorption while remaining lightweight and easy to store.
