Yet you don't own the property where your "home" is parked (likely illegally) though there is no realistic chance the state will verify you adhere to the river usage restrictions requiring you to move 5 nautical miles to a new location every 30 days.

You live in a public space (which is in almost every other circumstance prohibited), though in this case river usage rules did not account for people such as yourself, and so what you do is not currently illegal if you adhere to the rules of use.

As it stands, you are exploiting a void in public land usage rules, which have not yet accounted for the tiny percentage of persons who choose to live on the rivers.

With any luck, these rules will be modified, or the current usage rules actually enforced so that it will no longer be a possible alternative.
