It's the Law: On the Water

Obstructing Navigation

It is illegal to operate any vessel in such a way that it will unnecessarily interfere with the safe navigation of other vessels on the waterway.

You must not anchor a vessel in the traveled portion of a river or channel that will prevent or interfere with any other vessel passing through the same area.

It is illegal to moor or attach a vessel to a buoy (except for a mooring buoy), beacon, light or any other navigational aid placed on public waters by proper authorities. Also, it is illegal to move, displace, tamper with, damage or destroy any navigational aid.
