One more thing for you to plan... a graceful exit. You want your waterborne conveyance to be one that is easy to sell quick or at least give away at the end of your journey. You don't just bail overboard
and let it continue out to sea, and you don't just tie it up to a tree and split. Trucking your boat
home could be expensive. A true raft built of logs
and fully biodegradeable wood for your cabin
or shanty you could abandon, maybe. A drum raft you could disassemble and scrap. A sailboat you could re-step the mast
and continue across the eastern Gulf to FL and across FL to the Atlantic, then proceed North via the Gulf Stream
or up the ICW
, inland via the St Lawrence, and continue to close the loop. Or buy an old pickup and trailer
at journey's end, and drive home.
On second thought, a true raft might not work
so well. I forgot about locks and dams.
