Does anyone have the numbers for the Blackthorn/Sheridan?
Looking for a good set of numbers from someone who has actually been there. Have used some of the standard numbers on stuff before, and never found the wreck. Would rather be diving than motoring around hoping for the thing to show on the depth finder.
Also, are there surface buoys on these, or do we need to anchor?
The GPS numbers, along with the history of the USCG BLACKTHORN (and pictures of it) can be found in the book, Shipwrecks of the Sunshine State.
As mentioned, the large yellow Pinellas County Artificial Reef Program buoy is not on the BLACKTHORN, but is just off the bow of the SHERIDAN. If you swim off the bow of the SHERIDAN, you will intersect the wreck of the BLACKTHORN. The stern is broken off, but fairly intact, and the main hull is laying on its side.
There is also a barge just off the stern of the BLACKTHORN. It is possible to swim all of these wrecks on one dive. Again, all the numbers (for all three of these wrecks, and over 1,000 more) are in the aforementioned book.
