(Civilian tanker / 834 gt.) The so-called “Black Island Wreck” can be easily identified as a small tanker converted to carry specific fuel (gasoline, Diesel, lube oil etc.) in small isolated tanks for replenishment of land-based depots. The ship is approximately 50 meters long sitting upright on a sandy bottom.
Location: Close to Black Island Beach in front of the stranded vessel. This wreck is located 3.5 hours away from Coron. It is dived as a day trip with a 7 am departure. You would normally make one dive here and dive the Okikawa Maru as a second dive on the return trip. This dive site is perfect for beginner wreck divers and underwater photographers. It is a beautiful dive in clear water. You can see plenty of scorpion fish, lion fish, trumpet fish, groupers, and bat fish.

HISTORY OF THE ERROR IN NAMING THIS WRECK: The Japanese had many ships named Nanshin Maru. One Nanshin Maru was a Japanese freighter sunk in the Malacca Straits by a US submarine. There was also a tanker, the Nansai Maru ex. British oiler Ploiden, sunk at Black Island during WWII. This ship was captured in Hong Kong and renamed by the Japanese. The location of the Nansai Maru is not definitely known. It may be on the opposite side of Black Island in 60 meters of water.
