  A line joining Cape Catoche Light (21°37′N 87°04′W / 21.617°N 87.067°W) with the Light on Cape San Antonio in Cuba, through this island to the meridian of 83°W and to the Northward along this meridian to the latitude of the South point of the Dry Tortugas (24°35′N), along this parallel Eastward to Rebecca Shoal (82°35′W) thence through the shoals and Florida Keys to the mainland at the eastern end of Florida Bay and all the narrow waters between the Dry Tortugas and the mainland being considered to be within the Gulf.
