JZK is that a viable option? I'm a solar panel away from that being feasible for me and looking at SE Florida or maybe corpus christi depending on my work situation, but I have no issues with living on the hook. Is there legalities to consider? If I had a $2,000,000 house on the beach, I wouldn't want some wing-nut dropping anchor off it.
I know you can do that in West Palm Beach, Miami, and Key West. But that is by no means a complete list, just what I know of.
