The proportion of dozing in all ship accidents is about 7% (2005). The purpose of this study was to investigate ship accidents caused by dozing watch-keepers that actually resulted in marine accidents. Marine accidents that had been described to the judgment record of Marine Accidents Inquiry Agency between 1994 and 2003 were used for analysis. The authors investigated the relationship between the situations at the doze shipwreck and analyzed data, which included a 30-item categorization procedure. The analysis of fishing vessels revealed there was a notable relationship between the situation of "Generated in coast in Hokkaido" and the influence of "Work tiredness". The analysis of cargo ships revealed there was a notable relationship between the situation of "Watch by one person" and the influence of "Night shift". These results suggest that consideration of ship type may be necessary in developing counter measures.
