Fishing vessels generally have good performance in ship manoeuvrability. The relatively large rudder and propeller assist to make such performance, so there has been little need to the manoeuvering prediction. However, the manoeuvring prediction has become very important because the strong rudder force sometimes causes the capsizing accident. As for the principal dimensions of fishing vessels, they are different from conventional merchant ships. The ship length is generally small. The length beam ratio: L/B becomes less than 3.0 particularly in Northern Europe. Besides, they large initial trim by the stern. Therefore, the hydrodynamic force becomes quite complicated. This makes a difficulty when predicting the manoeuvrability of these vessels, In this paper, the authors show the database of hydrodynamic derivatives with several fishing vessels including the recent European wide beam vessel, and then introduce the empirical formulas to predict the hydrodynamic derivatives as well as other hydrodynamic coefficients based on the obtained database. Using these empirical methods, manoeuvring ship motions can be easily simulated and the manoeuvring prediction successfully done.
