We sailed a boat bought in The
Cayman Islands into
Key West last
winter. We went to a marina and called
Customs. They told us to come by the
customs office at Key West
airport withing 24 hours. No Problem they were very nice no issue. Look up the
phone number on
internet or a
phone book.
Had bill of
sale for boat and our passports, was all that was needed.
Sounds like a similar situation we had been out of US for about 30 days.
Good luck
