The incredibly prolific designer Paul Fisher's latest creation is the Deben 400, a rowing skiff based on the Cornish flashboat. It is much shorter at 4m (13ft) - the average flashboat is around 18ft - but has the same fine ends and low wetted area. It is a very light boat, Paul reckons it should weigh in at about 27kg (60lb). With no outriggers and a 1.2m beam that will fit on any roof rack it will be extremely easy to car top too. It is probably a bit tippy, as all flashboats are, but that is the price you pay for speed.
The name is a bit odd, though. The River Deben is in Suffolk, not Cornwall.
