I'd like to have water waves that will push my canoes along a stream. I've thought of the conveyor blocks in the Newton demo as a way to accomplish this. Maybe the Conveyor forces can be combined with the buoyancy demo and the wave action water shader.

Ideally the canoe paddle would react with friction against the water too, and propel the canoe...

Any ideas on how to do this?

I've seen many threads asking for boats enabled. Maybe a group of us could put it together.
