Overview
Nippon Maru (日本丸) is a Japanese museum ship and former training vessel. She is permanently docked in Yokohama harbor, in Nippon Maru Memorial Park. She was built by Kawasaki Shipbuilding Corporation in Kobe, and was launched on 27 January 1930 alongside her sister ship Kaiwo Maru. She was operated by the Tokyo Institute for Maritime Training to train officers for Japan's merchant marine. At the beginning of World War II, her sailing rig was removed and she served as a training and postwar transport motorship. In 1952, her rig was reinstalled and she resumed her training voyages until she was replaced in September 1984 by her successor, also named Nippon Maru. Nippon Maru measures 97 metres (318 ft) long, with a beam of 12.95 metres (42.5 ft) and a draft of 6.90 metres (22.6 ft). Her gross tonnage is 2,286. She is rigged as a four-masted barque, with 32 sails covering 2,397 square metres (25,800 sq ft), and two 600-horsepower diesel engines for auxiliary functions. During her career as a training ship, she was manned by a crew of 27 officers, 48 seamen, and 120 trainees.
Composite Risk
Multiple adverse factors, or a hard ship-specific signal, lift this hull above the fleet norm.
A coverage-weighted blend of the single component we could read for this hull; the weights renormalise over only the components present, so a thin read is never inflated and a hull is never credited a “safe 0” for a signal it has no row for. This headline is flagged low-confidence (a thin or structural-only read) and should not be treated as a verdict. Higher means riskier. Derived in-house from government-open port-State-control, flag, sanctions and our own vessel data; weight it by the coverage above.
