Cayman Salvager

#38 - Cayman Salvager

USA, Florida, Keys, Lower Keys

intermediate

The Cayman Salvager now lies one mile southwest of the Nine-Foot Stake. This 187-foot steel-hulled buoy tender was built in 1937 for Coast Guard usage and was later used as a cable layer and for freighting. The US Government seized this vessel because she was carrying Cuban refugees during the 1979 Mariel boatlift. After being seized, she was sitting at the dock awaiting her fate when she sank unexpectedly. In 1985, she was raised and prepared to be sunk again as an artificial reef in 300 feet of water. But while being towed out for re-sinking, she prematurely sunk in just 90 feet of water where she currently resides. She settled on her side but was kindly righted a few months later in 1985 by Hurricane Kate. In preparation for her scheduled sinking, the Cayman Salvage had been cleaned and stripped to create a smoother structure to foster pelagic life. Because of the removal of restricting parts, penetration is possible but is considered dangerous. It is recommended that divers who desire to pursue such a mission do so during a return dive and not on the first exploration. Bar jacks and schools of silversides frequent this site. Divers have reported that a 200-pound jewfish and a six-foot green moray eel call this vessel home. Note that dangerous aspects of this location are strong currents and the depth. A careful diver will find this artificial reef a great chance for exploration and a unique dive. This site can only be reached by boat. Any Key West dive operator will take you to it.

This reef gets its name from its curved shape. There's a bunch of large coral heads that grew in a semi circle shape. This formation is on the northeast corner of the reef.

This reef has several sandy ledges running east to west. This is a likely place to catch a sea turtle sleeping during the day. Nurse sharks like to hang out here too. Just in case you don't know, Turtles are a protected species. It's illegal to disturb them in any way. So don't try to touch them. This is a great dive site to bring along an underwater camera.

Spiegel Grove sunk June 10, 2002. This is the largest ship ever sunk intentionally to be an artificial reef, and probably the most well known. Vessel size: - length: 510 feet - type: U.S. Navy Landing Ship Dock - tonnage: 6,880 tons It takes at least two dives to have a look of the wreck. The Spiegel is an excellent Nitrox dive, especially on double tank dives! In July of 2005, Hurricane Dennis forced the former USS Spiegel Grove onto her keel, right-side-up, which was the position originally intended when she was sunk. It is an amazing dive. Great areas for advanced and limited penetration. This wreck offers something for everyone multiple times. You could dive it 10 times and not see everything. 6 Miles off Key Largo. The Spiegel Grove wreck lies near Dixie Shoals into the Marine Sanctuary. Spiegel Grove is also known as LSD-32.
