We spent a week on a mooring
ball in Garrison Bight City Marina Mooring
Field along with 50-60 other boats. On the way there, we passed the cruise ship
terminal downtown and many more boats at anchor
or on moorings. To see them, go to Key West Bight and look out to the west. The mooring field we were in is a bit harder to see.
Don't know about any interesting marine stores - was too busy trying to find parts
, fix things, and help the wife with her work to look around. West Marine does have a store on Caroline Ave near downtown. There is a Kuban Marine store in the same area but we did not visit it.
Some day I would like to go back to Key West and spend some time looking around. It seemed like a nice place to visit.
