many of the
marinas on the page HyLyte posted will not be suitable for you and some are really not
marinas. You did not say when you will be there. Several marinas especially in the middle keys have closed and several more have gone condo so there is a real shortage. During high season you might not be able to find a slip. The best deal are the moorings in Boot Key Harbor at the City of Marathon Marina. Both Marathon Marina (not the City Marina) and Sombrero Resort have been bought out and are now VERY expensive and the facilities at the former Marathon Marina is nothing more than a working boatyard. Dockside Marina has gone condo so for $250,000.00 you could own your own slip. They had been
renting some slips for transients but don't know if that is still so. You can find nice slips at Bonefish Marina which is condo but does rent out some slips. It is way out of town though. Naturally you should not have a problem in
Key West but bring all of your bank accounts. Hope this helps a bit.
