Unless you are diving a nitrox mix, bottom time might be short but the tug is small and easy to explore. The Pilot house is great and the compartment is ribbed out over the engines and easy to see inside. The wreck is quickly deteriorating and should never be penetrated. The Japanese Tug is located at the bottom of Apra Harbor Guam between the Tokai/Cormoran and the Kitsugawa. The Tug lies in 135’. The shallowest point is about 85’ at the top of the mast and 115’ at the main deck.
