Florida and Documentation is something I actually DO know something about. IF a Documented Vessel is "primarily used" in FL, then FL collects the same Registration Fee as if the Vessel were not documented. Same as if it were displaying FL Numbers. Except only the Annual Registration Sticker (usually displayed before or after the FL numbers Port Side) is displayed, on a Port Side Cabin Window. If, say, Texas was otherwise equal but did not require registration of documented vessels, then that point would favor TX.
