Actually, on any waterway, if a boat passes within 300 metres of the shore and generates oversized waves, it will always cause erosion. As Vermont has done, I believe it would be much easier to establish national science-based standards than to ask every municipality to implement regulations and provide evidence for each of its waterways.
In fact, the Municipalité de Nominingue took seven years to regulate one of its waterways. It has practically 100 within its boundaries. It took seven years to regulate a single waterway. Some standards may be applied, perhaps not for the boat limit because that obviously depends on the body of water, but for the distance from the shore. For example, for sports generating oversized waves or maximum speed at a certain distance from the shore, that distance would ultimately be the same in any body of water.
