Blackthorn
The U.S.C.G. Blackthorn is one of the most popular wreck dives in the Tampa area. The buoy tender served nearly 40 years in the U S. Coast Guard maintaining navigational aids, breaking ice on the Great Lakes and assisting in salvage missions as well as rescues of sinking vessels. At its launch in July 1944, the Iris-class tender was one of the largest class of tenders in the Coast Guard. The ship served in the Great Lakes region and offshore of California before undergoing renovations in Tampa in the 1970s and moving to home ports on the Gulf of Mexico.
The Blackthorn had just completed additional renovations in Tampa and was leaving port for Galveston, Texas, when she collided with a huge freighter. As the 605-foot S.S. Capricorn headed into port in the long channel shortly after night had fallen, the helmsman?s view of outbound ships was briefly blocked by a brightly lit Russian passenger ship. Unfortunately, Blackthorn?s commanding officer had left the helm with an inexperienced officer who was unable to maneuver away from the Capricorn once they spotted each other. The 180-foot tender collided nearly head-on with the freighter in the center of the channel, just west of the Sunshine Skyway Bridge.
The Capricorn's anchors were in position for docking and one lodged into the side of the Blackthorn. The inertia of the ships caused the Blackthorn to be dragged first backwards, then sideways. The Capricorn's anchor line wrapped under the Blackthorn and as it tightened, the Blackthorn capsized. Twenty-seven crew escaped the rapidly sinking ship, but 23 seamen lost their lives that night. Within ten minutes the Blackthorn had sunk in 40 feet of water.
Three weeks later, the ship was raised but the damage was too extensive for repairs. The Blackthorn was towed 20 miles offshore to the Pinellas #2 Artificial Reef Site and sunk in 80 feet of water. The ship is broken into two large sections which rise 15-20 feet off the bottom. The major sections are upside down. Penetration is not recommended. The area has a large amount of silt making visibility poor. The ship has become heavily encrusted and has attracted a large amount of marine life. Goliath grouper, snapper, mackerel, schools of spadefish and even some whale sharks have been spotted in the area. The Sheridan is just 200 feet away from the Blackthorn.
Sheridan
The Dive - per me :winky:
Sheridan
The Sheridan lies within the Pinellas #2 Artificial Reef Site and is just 100 yards southeast of the USCG Blackthorn. The Sheridan is a fantastic wreck dive. The 180-foot tugboat lies upright and fully intact in about 75-80 feet of water. The tug lists about 50 degrees to starboard with its prop in place. The top of the wreck can be reached at 25-30 feet. The wreck is surrounded by concrete culverts and tires.
Many consider the Sheridan to be one of the best wreck dives in the Tampa/Clearwater area. The Sheridan is home to several Goliath Grouper and barracuda and always has lots of marine life to observe. Spanish mackerel, amberjack, crevelle jack, trigger fish, snapper, and even the occasional shark frequent the reef site. This is a great spot to take pictures of some large grouper. Advanced wreck divers will enjoy exploring the open compartments.
