I was Wondering who has done an RC Vid of a Boat Being Used in a River and going up stream as opposed to down?

I was Just watching some Jet Boating Vids and thought there has to be a way to do RC Boat Racing that isn't done round water Markers but more of a Natural Course like a Creek or river?

So an RC Boat Rally if you can understand what I mean, RC Boats that Display more Torque then Speed?

Some Really wild RC Boating as opposed to Standardised Racing.. I suppose Boat Bashing would be a more appropriate Term??
