Every public-access marina from the St. Marys River south to the Halifax — mapped, verified, and free. Slip counts, boat-size limits, fuel availability, and current amenities for the working chart cruisers, transient boaters, and waterfront buyers actually need. Click any marker to see the data; scroll the directory below for the full breakdown.
Grouped north to south along the Atlantic ICW. Each entry shows the verified slip count, year established, accepted boat types, on-site amenities, and the marina's direct phone + website. Where a data point isn't published, it's marked "Not published" rather than estimated.
Each marina was verified against three independent sources before inclusion: (1) the marina's own current public website, (2) a cross-reference against BoatUS Marina Finder, Waterway Guide, and Garmin ActiveCaptain community data, and (3) state regulatory records — the Florida Department of Environmental Protection's Clean Marina program for FL entries, and Georgia DNR Coastal Resources for GA entries.
GPS coordinates were resolved using each marina's published address through Google Maps. Year-established figures come from each marina's "About" or "History" page where available; where a marina has not published a founding year, it is marked "Not published" rather than estimated. Slip counts use the marina's own current published figure or, when that's unavailable, BoatUS/Waterway Guide data with the year of that source noted.
Boat-type acceptance reflects the maximum LOA accommodated as published by the marina; sailboat draft and mast-height clearance to reach the marina from the open ocean depend on the specific approach channel and bridge clearances and should always be verified with the dockmaster. Power vs. sail acceptance is implicit unless the marina explicitly excludes a type.
Coverage spans approximately 150 nautical miles of the Atlantic Intracoastal Waterway, from Brunswick Landing Marina at ICW mile ~680 down through the St. Johns River corridor and the ICW south to Halifax Harbor Marina at ICW mile ~830. The directory does not include private community docks (HOA-restricted facilities), single-family-dwelling docks, or bait-and-tackle ramps without overnight slip capacity.
The directory above is the working chart. These three pillars cover the buyer math, ownership structure, and operational reality behind every slip on this coast.
Slip rates, hurricane plans, waitlists, ICW vs. river math, bridge clearances, and when to buy a house with a private dock instead.

Read the guide →This directory was assembled from each marina's own published material plus the regional and national references below. Every marina entry links to its own website; the references below are the cross-check sources used to verify slip counts, fuel availability, and regulatory standing.
Each marina's official website is linked directly in its directory card above. Marinas omitted from this directory either could not be verified against at least two of the cross-check sources above, are private (HOA-only or member-only with no transient access), or have been reported closed/unmaintained at the time of last verification (June 2026).
Whether you're a cruiser scouting a southbound winter slip, a retiree wanting a Doctors Lake bungalow with a private dock, a Navy family relocating to Mayport, or a Brunswick transient looking for a permanent home base — Tim Sherman knows the docks, the dockmasters, and the houses that come with permitted private slips. No marina kickbacks. Just the chart.
