Default Where Florida and Alabama 9NM Waters Meet

Tried to get a handle on just where the Florida and Alabama 9 Nautical Mile lines actually meet so I could show that on my GPS/Sounder. Tried to Google search for the information but couldn't get a definitive answer. Then I found that the Florida Constitution actually sets the longitude line as an extension of the on land state boarder boundary as 87 degrees, 31 minutes, and 06 minutes. I converted that to Degree Decimal format so that half of the coordinates is -87.51833333. Then I used Google Earth and marked that longitudinal line extending offshore. Now for the next part you need to remember that a land mile is not the same as a nautical mile. A nautical mile is defined as being 1.1508 statute (land) miles so 9 nautical miles is actually 10.3572 land miles. I used the ruler tool in Google Earth to draw a circle with a radius of 9 NM and placed the center of the circle at the shoreline so that the radius line extended out perpendicular from the shoreline to the point on the circle, the radius line and the longitude line all came together. The coordinates at that spot which I call "The Florida Alabama Peg" are:
Latitude = 30.125580 and Longitude = -87.5183333. Remember that the Longitude is absolute because it is set by the state constitution. The Latitude is only as precise as my ability to use the Google Earth circle tool but I'm confident that my Latitude is within plus or minus 50 feet on the Longitude.

I have no idea what is right or wrong. Are your numbers right or is this maps line positions correct??

On a computer place your map over the red drop pin (your coords.)and it says you're off a bit. Close the warning boxes first. Does great circle distance factor in? I wouldn't worry too much myself.

yes, this a very technical question. we pulled into sportsman marina last snapper, season, the capt. reported the catch and then comes the feds. we had to go back to the exact same spot we caught the fish and they checked coords and it was legal. what some bs.

I'm not sure this is correct. This was changed for purposes of fisheries management, but not sure it was permanent or that it is for every state or that it was for everything including oil and gas, etc.

Alabama changed it. According to Outdoor Alabama,
"Recently, the US Congress passed a provision that extended the state water jurisdictions for the management of certain fish from 3 nautical miles to 9 nautical miles offshore for Alabama, Louisiana and Mississippi. Florida and Texas already had this jurisdiction. Below are answers to a few frequently asked questions on this issue.

If you have additional questions contact the Alabama Marine Resources Division at 251-861-2882 or by email at [email protected]."
