Polyform Norway
World-leading fender design, trusted by professionals since 1955.
Innovation, strength, and performance in every Polyform fender.
Polyform Norway created the world’s first inflatable fender and continues to set the global standard. Built using patented POLYMATIQ® technology and reinforced rope holds, each fender delivers unmatched durability and protection for boats of all sizes.

Choosing the Right Fender Size

Get the best protection for your boat by matching fender size to vessel length, mooring style, and conditions.

The right fender size makes all the difference in protecting your boat from impact damage. As a general rule, use one inch of fender diameter for every 4–5 feet of boat length, and always go larger for rougher waters or heavier craft. Consider how and where you moor — side-on docking needs more coverage than a fore-and-aft tie. Whether you need cylindrical fenders, spherical buoys, or specialist shapes, we'll help you choose the right fit for peace of mind on the water.
