Valley did a great job of keeping the boat stiff despite its proportions but the weight of all that plastic is really apparent when it comes time to turn. I am not sure, but the knee space feels slightly more livable in the Nordkapp than in the Avocet, for my 185lb 6' frame.
Valley uses a wire rope type skeg cable which is prone to bending if forced or jammed in any way. Not a problem if you take care but don't loan it out to ham-fisted friends. After five years (of harsh conditions)the foam bulkheads required an application of sikaflex to restore seaworthiness. The double seal on the hatch covers is solid, but all of the British style hatch covers seem to have a life expectancy of a few years before they crack out- As do the thigh braces made out of a similar dense rubber foam- those have cracked out too and are currently held together with glue and duct tape.
Overall, the Nordkapp is a seaworthy vessel, purpose built to put miles on- but there will be no resting in big waters.
