I cruised my 8 ft
draft Beneteau up and down the
east coast for several years, and have done Florida from
Jacksonville to
Key West.
I don't know why you are set on Florida. We have a house guest from Ft Lauderdale. She bought a one way ticket to
Santa Cruz, and isn't going home until
Fort Lauderdale cools off. She is tired of being cooped up in an air conditioned house, and getting up at 5 am to go for a walk.
If you are still bent on going, you should realize that northern Florida has winters. I remember being on the
boat in 26 degree nights in St Augustine. That is not the case south of West Palm Beach.
As far as 8 ft goes, the
ICW is out. Look at the detailed charts to see how deep the channels and
marinas are.
St Augustine has several
marinas that carry more than 8 ft. The inlet is dodgy at low tide.
Fort Pierce has a deepwater inlet, but the anchorage is less than 8 ft. We had to
anchor in the main entrance, which did not
work well with
wind against tide.
Fort Lauderdale is doable for marinas, but moving around at low tide is not.
I looked at Biscayne Bay on the charts, and decided to give it a pass.
Key West is a different country. Stayed at
anchor there for a month, but cold fronts can be uncomfortable with dragging boats, and moving around at low tide is out.
I'm sure that there are places available if you are motivated enough. The
classic Merlin is being homeported in Tampa Bay and she draws 11 ft (but currently like our guest she is on the West Coast).
