meant by rocker, though. First, I recently saw plans by John Winters for an 18' 6" cruiser where he had trimmed away the stern, a bit, and the bow, quite a bit, leaving quite a bit more "rocker" than my old 18.5' Moore. Yet I know that, although they are otherwise similar, the Winters boat is going to be as fast on rivers and faster on lakes.
The issue is, what is that stuff added on to "reduce" rocker doing to help forward progress? Sometimes, not much.
On ww canoes, which are not usually cruised hard, the rocker may cause the bow to "push" water out of the way, rather than part it, but both of my ww canoes, with a proper load, angle up over the water very gently, and do not plow or push the water. Their rocker means that they have low wetted area, and as long as I'm not trying to keep up with the downriver boys, the ww boats accelerate very effectively and cruise easily. Not fast, but easily.
The effect of what we call rocker can only be understood in the context of each individual design. A canoe that's genuinely fast in some ways may have quite a bit of rocker in the form of lift at the ends. Even 60' 8 man rowing shells have it. And, if one avoids a bow that plows and pushes, a high rocker ww boat can be a great accelerator and an easy paddler.
