Rules and laws, yes indeed. And they will vary in each state, and even from county to county or municipality within each state. Then once you get down to Florida, if you are in-state for more than 90 days, they may also demand that you register the boat in Florida and everything that goes along with that. Like taxes.
Now with the 90 day thing. So if I leave the state every 90 days is there a mandatory period that I have to stay away? Or is a simple weekend trip to the next state over sufficient?
