Once long ago, I went canoeing, and ever since, have wondered why they didn't make an arrangement like that for canoes. It would let you go longer, faster, sit lower, etc, if done right.
On a lot of canoe and kayak trips, people are just floating with the current, and it wouldn't be as much of an issue then. But I went canoeing on a lake.
They did have the little pedal boats, but those are woefully inefficient and not something you'd want to use to go anywhere.
