The reefs are subject to moving with strong current. They have gone a good distance since they originally dropped all that stuff years and years ago.

That makes sense didn't think about that, thought they were just messing with us...

A lot of those numbers were converted over from loran so it's not accurate to begin with...

Here is a good rule of thumb I have found. If the coordinates have only 2 decimal places at the end, you are looking at bad numbers. All the dive sites, that are not afraid of over use, use 3 decimal places to mark the sites. Other than the minute effects of continental drift, most of the ARs should be just about exactly where they settled. There are exception, but most of the materials (concrete and steel primarily) used have a high weight to surface area. So, storm conditions have virtually no effect on them. Also, most of the ARs are in depths beyond the reach of most storm surge. Not that the water does not move down there, but you don't see the effects like waves breaking on the shoreline.

That being said, I am not sure if the bad coordinates are due to intentional misleading, bad conversion or the built in error factor of GPS. Probably a combination of the three.
