I think I have found a way to to make the mixed boat idea work. We just incorporate this "sport" with sailing.

There's a pole (mast). This would solve the viewing problem. What could better to watch than a cat screaming downwind in 20kts with some girl doing moves on the mast.

Just curious, are we going to have a mixed 100 yard dash, basketball, etc.
