I have dove this site twice, both off of a boat as well. I actually did one of my open water cert dives here. The vis was pretty good, until our class got there at least...but, anyways... I have also dove here when the vis was so bad you had to hold your gauges to your mask to read them, so it does fluctuate. I have only heard of this site referred to as the Maury island barges. Would definitely like to know how to access it as a shore dive.
