Sea Hag Marina is one of the largest full service marinas on Florida’s Big Bend. Located at Marker 47 on the Steinhatchee River, Sea Hag is also the closest marina to the Gulf of Mexico in the area. We are accessible by car from either SR51 (from the panhandle and South Georgia) or CR358 (from Gainesville and all points south). Both roads intersect US19 just a few miles to our east.
