I've had a CLC 16, Pax 20, currently paddle an expedition single, and row a 17' cedar canoe. They all go about the same speed over distance it seems...about 4 knots or 5mph. I am 6' tall and weigh 180 lbs. I have plans for s&g shearwater but am attracted to the WR 180 for its speed potential being slightly longer and its multichine look. I paddle a large lake so its railroad steering is not a big problem to me and I'd like a second kayak for general paddling and occasional bursts of speed. What would you do?
