The Story of Polyform Norway vs. Polyform US
The Polyform story originated in the picturesque coastal town of Ålesund, Norway, in 1955 when its founders invented the world's first plastic buoy. This invention became the cornerstone of the business. In the 1970s, Polyform US was established in the Pacific Northwest and continues to thrive as a family-owned business, designing and producing all products in Kent, Washington. We proudly offer both Polyform AS (Norway) and Polyform US products on our website, maintaining a brand-neutral approach.

Polyform fenders sizing
Not sure which size of fenders do you need for your boat? In fender sizing a simple rule of thumb applies - approximately 1 inch/25 mm of fender diameter for every 4 or 5 ft/1,2-1,5 m of the boat length (LOA) for cylindrical fenders. For round fenders approx. 2 inch/50 mm for every 5 ft/1,5 m of boat length.

Polyform US recommends F2 fender for boats ranging from 20 to 30 feet. Polyform AS’ recommendation corresponds to boats of approximately 26 to 30 feet (6-8 m) in length. F4 fender is recommended for boats from 30 to 35 ft by Polyform US, while Polyform AS suggests it for slightly bigger boats of approximately 32 to 39 ft (10-12 m). As we go into bigger fender sizes Polyform US suggests F6 fender for boats of 35 to 50 feet. For Polyform AS range this fender is recommended for boats between approximately 50-52 ft (16m).

There are no consistent differences between the two brands. Each size may vary in length, width, thickness, and weight, with Polyform US offering a broader range, especially at the smaller sizes extending into HTM & NF series. These distinctions likely stem from subtle optimisations in their product lines.
