A data base of Japanese fishing vessel casualty records has been constructed in order to analyse casualty tendencies concerning with flooding, capsizing or sinking accidents. The significant data of every accident have been picked out from the documents describing the decisions by the Japanese Maritime Disaster Inquiry Agency for ten years 1978-1987, and the necessary items of each record have been stored on a computer treatable data base. One data record consists of various items, for example the ship data, fishing type, results of accident, environmental conditions, causes of the accident due to the environmental conditions, construction of the vessel or human factors. Total 370 cases have been stored. Analysing of the data base, some typical patterns have been derived for the fishing types and size of vessels. It has been found that the shipping water is the main cause of the accidents of fishing vessels in rough weather. The accidents happened almost equally independent to the wave encounter angle of head (incl. bow), beam and following (incl. quartering) seas.
