When any teaching staffs have to be in charge of the subject they've never experienced,elaborate preparation will be required until the new semester starts. However,it is difficult to obtain these kinds of information in sea training under local weather conditions. In this paper,the author considers an improvement of the cutter training through his teaching experience in college.Firstly,descriptions and requirements of the training are summarized to implement lessons every week.It is famous that tidal current's speed is very fast near the training sea area.Then,weather and oceanographic database is analyzed from April to October.This reveals that wind speeds sometimes rapidly increased in spring seasons,so it is more difficult to predict.Tide levels have been observed for 3 months to simulate spatial distribution of tidal currents around the training sea.Numerical simulations of tidal currents are implemented to verify the spatial distribution of them.Finally,the information system of safety judge is considered to operate the sea training as the new education tool.
