Consequently, the sea traffics are drastically congested, especially in the harbours and along the coast. Accordingly, safety navigation and enhancement of maneuvering efficiency have been greatly thought of but every year there are quite amount of sea accidents. Exceeding speed forms a high percentage of the cause of sea mishaps under fog. Taking this into consideration, Harbour Maneuvering Technic Study Group of the Kobe University of Mercantile Marine has made a research of ships passing the Akashi Strait and have taken photographs of rader images for one year from March 1963 to February 1964.
