The Prelude's chines actually soften over time as the bottom of the boat begins to round a little. This actually makes it even easier to surf--you can recover more easily from a dropped edge. The boat has held up well from 50+ days of paddling a year. The hull has lots of scratches and nicks, but is sound. There is some oil canning under the seat, but it doesn't seem to hurt performance.
I'm so sold on the boat, I already have a spare tucked up in the rafters of my garage in case I crack the hull at some point.
This boat is rotomolded and made of polyethylene, the same plastic they use for whitewater kayaks. This makes it tougher than Royalex boats and allows it to slide more easily on rocks. It comes with an already installed foam bulkhead saddle. The seat is 10" high, too high for such a short, narrow canoe. I carved the seat down to less than 8" high.
I'd give the boat a 10 if they could find some way to offer it with adjustable thigh straps instead of the foam bulkhead. Overall, I'm very happy with the Prelude.
