The City recognizes that there are times when a fast approaching storm or nightfall descends upon the mariner and an anchorage area is a welcome sight. There are several established areas where traditionally the cruiser has dropped anchor in the City waters for a comfortable stay. The following areas are intended for short term transient use only and are serviced by the City pump out boats called upon demand. The entire Florida Keys are a designated “No Discharge Zone” and as such, we ask that you close and seal your sanitary through hull discharge fittings during your stay in these waters.

Bone Fish Bay Anchorage

24.43.895 N
81.00.681 W

The most protected harbor in the City is Boot Key Harbor at the west end of the City.  At the east end located between Grassy Key and the City of Key Colony Beach on the Atlantic side of the Keys is Bone Fish Bay. The entrance is well marked by day markers with a controlling depth of 6 ft. Shoaling and winding channels occur at the entrance so it is a good idea to use high angle light on the first trip in and out. There is a long canal that takes you into the well protected harbor. The amenities are sparse, most of the landing ground is privately owned. There is a seafood market, outboard repair shops, a boat yard with a wheeled open end boat lift, and a convenience store within walking distance. The boat yard allows dinghy customers to access uplands.


Boot Key West Anchorage

24.41.805 N
81.07.095 W

The only other anchorage located on the Atlantic side of Marathon is on the west side of Boot Key south of the entrance to Boot Key Harbor.  This anchorage is best in the lee of the island with a prevailing southeast and easterly wind to the northeast. The anchorage provides a quick getaway on a cruise or a chance to find air on calm evenings. There is good holding ground and consistent depth contours. Three great restaurants, a marine store, two boat yards, and three fuel docks/stores are within a short dinghy ride from this anchorage.


Tranquility Bay Anchorage

24.42.766 N
81.06.184 W

Half way between the Coast Guard Base and the Marathon Yacht Club on the north side or Gulf side of the City is a beautiful anchorage for all but strong northerly breezes. This area is not well protected but affords good anchoring with south winds. There is good holding ground and consistent depths throughout the area. You can dine at several waterfront restaurants in this area.


Vaca Cut Gulfside Anchorage

24.44.023 N
81.01.276 W

Just to the east of the entrance to the Vaca Cut Channel, Gulfside, between the Quay Restaurant and the Island Tiki Bar and Restaurant is a small anchorage suitable for the overnight stop along the inter-coastal waterway. This anchorage has good holding ground, is protected from all but north to northeasterly winds. There is an on-the-water restaurant within a dinghy row away.
