Dive into history and adventure with Ocean Therapy Charters as we explore the Navy Tug off the coast of Oahu. The USS Nashua (YTB-774) is a former US Navy ship, built in 1965 by Marinette Marine. It belonged to the Natick class Large District Harbor Tugs, measuring 106 feet in length with a beam of 29 feet. Primarily used for towing and pushing naval ships at Subic Bay Naval Station, Philippines, it also served in firefighting and harbor patrol roles. After the base closed in 1992, the Nashua was transferred to Pearl Harbor and decommissioned in 1994. The vessel was intentionally sunk in 2012 to serve as an artificial reef and a training site for the Navy's Mobile Diving and Salvage Unit One.
This site is situated outside of Pearl Harbor and rests at a depth of about 65 feet (20 meters) making it accessible to divers of various skill levels. Reaching the wreck requires a bit of longer boat ride than other South Shore dive sites from the Ali Wai Harbor. Combined with the Ewa Pinnacles, these sites are available on a select schedule each month weather permittng and for all of our Private dive charters.
Our experienced guides ensure a safe and unforgettable journey, providing insights into the wreck's history and the diverse sea creatures that now call it home. Whether you’re an avid diver or seeking a once-in-a-lifetime experience, this dive promises awe and wonder beneath the waves. Join us for an adventure that blends history, nature, and the thrill of discovery.
