Question.
As the water is owened/cvontrolled by the EA. Then if the canoe does not land or touch bottom are they tresspassing.
As it would be like a plane flying over your land. They would be depriving the EA of services rendered as there using the water.

Good analogy with the airplane, Bryan.
In this country, no-one owns the air space above their property, but the CAA (is it still?) control the flightpaths etc for passenger airplanes, less so for gliders and such.
In Manhatton, the land owners DO own a certain amount of air space which is why churches, whose buildings can only be so tall, could sell off their remaining 'right to airspace' to neighbouring landowners to build enormous skyscrapers. Nothing to do with rivers, but interesting all the same.
A pity we don't own the air space above our house with a nearby airfield I could charge a hell of a lot to all those who fly over. I always wondered what the tyremarks on our roof were when we first moved in.
