USS YO-257 was a Yard Oiler of the United States Navy that was scuttled two miles off Waikiki, Honolulu, Hawaii in 1989. [2]
Built in 1938, YO-257 saw action in World War II, the Korean War, and in the Vietnam War. [3]
From 16 September to 12 November 1963 the ship was temporarily loaned to the Coast Guard to assist in the construction of a LORAN radio navigation station in Yap, Western Carolines, carrying water-based asphalt to be used for a runway for aircraft servicing the station.
After decommissioning, the ship was purchased by Atlantis Submarines Hawaii, who sank it as an artificial reef. The sea floor surrounding the ship is approximately 100 feet (30 m) deep, and the top deck of the ship is roughly 85 feet (26 m) deep. Directly abeam to the YO-257, colloquially called the YO by area divers, is the San Pedro, intentionally sunk by Atlantis Submarines in 1996. The two ships are visited frequently by Atlantis and are popular dive sites. There is sometimes a strong current at the surface, which eases as you approach the wreck. A descent line is always rigged to mooring buoys on the wreck. The typical dive profile is 90 feet for 20 minutes. [4] There is a preponderance of marine life on both ships, mostly turtles and reef sharks, such as the whitetip reef shark.
Wreck diving is recreational diving where the wreckage of ships, aircraft and other artificial structures are explored. Although most wreck dive sites are at shipwrecks, there is an increasing trend to scuttle retired ships to create artificial reef sites. Diving to crashed aircraft can also be considered wreck diving. The recreation of wreck diving makes no distinction as to how the vessel ended up on the bottom.
Diving activities are the things people do while diving underwater. People may dive for various reasons, both personal and professional. While a newly qualified recreational diver may dive purely for the experience of diving, most divers have some additional reason for being underwater. Recreational diving is purely for enjoyment and has several specialisations and technical disciplines to provide more scope for varied activities for which specialist training can be offered, such as cave diving, wreck diving, ice diving and deep diving. Several underwater sports are available for exercise and competition.
An artificial reef is a human-created underwater structure, typically built to promote marine life in areas with a generally featureless bottom, to control erosion, block ship passage, block the use of trawling nets, or improve surfing.
USS Spiegel Grove (LSD-32) was a Thomaston-class dock landing ship of the United States Navy. She was named for Spiegel Grove, the home and estate in Fremont, Ohio of Rutherford B. Hayes, the 19th President of the United States.
Toa Maru No 2 is a World War II Japanese transport ship sunk by the American submarine USS Searaven (SS-196) off Gizo, Solomon Islands on 25 November 1943.
Shark tourism is a form of eco-tourism that allows people to dive with sharks in their natural environment. This benefits local shark populations by educating tourists and through funds raised by the shark tourism industry. Communities that previously relied on shark finning to make their livelihoods are able to make a larger profit from diving tours while protecting the local environment. People can get close to the sharks by free- or scuba diving or by entering the water in a protective cage for more aggressive species. Many of these dives are done by private companies and are often baited to ensure shark sightings, a practice which is highly controversial and under review in many areas.
MV Adolphus Busch was a cargo ship that was sunk off of Looe Key, Florida, as an artificial reef and dive site.
Atlantis Submarines is a Canadian passenger submarine company. The company currently has 12 submarines and operates undersea tours in Grand Cayman, Barbados, Aruba, Guam, St. Thomas, Cozumel and in Hawaii at Kona, Maui and Oahu.
USS Greenlet (ASR-10) was a Chanticleer-class submarine rescue ship in service with the United States Navy from 1943 to 1970. In June 1970, the ship was transferred to the Turkish Navy, renamed TCG Akin (A-585) and remained in service until 2017.
German submarine U-701 was a Type VIIC U-boat built for the Nazi Germany's Kriegsmarine that served in the North Atlantic during World War II. It was launched on 16 April 1941 under the command of Kapitänleutnant Horst Degen, with a crew of 43.
Wreck Alley is an area a few miles off the coast of Mission Beach, San Diego, California with several ships intentionally sunk as artificial reefs and as Scuba diving attractions for wreck divers.
Sinking ships for wreck diving sites is the practice of scuttling old ships to produce artificial reefs suitable for wreck diving, to benefit from commercial revenues from recreational diving of the shipwreck, or to produce a diver training site.
Glen Strathallan was a British ship originally built as a trawler, but then converted into a private yacht, which also served in the Royal Navy in World War II. She was finally scuttled in 1970 at Plymouth Sound, England as a diver training site.
Recreational dive sites are specific places that recreational scuba divers go to enjoy the underwater environment or for training purposes. They include technical diving sites beyond the range generally accepted for recreational diving. In this context all diving done for recreational purposes is included. Professional diving tends to be done where the job is, and with the exception of diver training and leading groups of recreational divers, does not generally occur at specific sites chosen for their easy access, pleasant conditions or interesting features.
Carthaginian II was a steel-hulled brig outfitted as a whaler, which served as a symbol of that industry in the harbor of the former whaling town Lāhainā on the Hawaiian island of Maui. Built in 1920 and brought to Maui in 1973, the square-rigged tall ship served as a whaling museum until 2005, and after being sunk to create an artificial reef, now serves as a diving destination.
