Worth knowing
Rotostøp AS; cover, cost and conditions
Rotostøp AS is a Norwegian company that makes River boats, small motorboats moulded from impact resistant polyethylene. The material is fully recyclable, and the hull is a hybrid between catamaran and V-bottom, giving the boats strong sideways stability. They are light enough to pull up a beach and need very little upkeep. The number in the name is the length in centimetres (290, 350, 420, 460), and XR marks the version with a steering console.
Our model records list 7 designs, all motorboats: the River 290, 350 and 420, each as a standard boat and as XR, plus the River 460 / 460 XR. The 290, 290 XR and 350 start in 2004, the 350 XR, 420 and 420 XR in 2005 and the 460 in 2017. The standard 290, 350, 420 and the 460 are recorded into the latest build years, while the 290 XR and 350 XR end in 2021 and the 420 XR in 2022. Lengths run from 2.9 to 4.6 metres.
A River boat lives on a cabin jetty, a car roof or a beach in Scandinavia, ready for fishing or a short hop across the fjord. Polyethylene shrugs off rocks and needs no antifouling, so care comes down to rinsing, checking the outboard and storing the boat upside down or under a tarp in winter.
