HOKUYO MARU 
The Hokuyo Maru was built in 1937, by the Urega Dockyard Senryu as a medium coastal freighter for the Kita Nikon Kisen Line. She was designed to operate between North Korea, Hokkaido and other Japanese islands and as a result had a very strong bow to penetrate the ice flows.
During the "Hailstone" attack, Hokuyo Maru was attacked by aircraft from the carrier Essex and sunk by a bomb that struck her stern. She now lies in 200 fsw.
Hokuyo Maru: Displacement: 4,217 tons; Length: 354 feet; Beam: 50 feet; Engine: 1 low pressure steam turbine / coal; Max Speed: 15.85 kts.
