Since International Maritime Organization (IMO) has adopted "The Standards of Ship Maneuverability" as IMO Resolution MSC.137(76), the ship maneuverability is evaluated under this standard. Therefore, we have to know the accurate ship maneuvering characteristics at the design stage, especially the initial design stage. On the prediction method of ship maneuverability, there are many papers for estimating method of the maneuverability of a ship based on the model test, but there are few papers

The authors have already proposed the simple, accurate and practical prediction method for the ship maneuverability of model ship. So, we need to develop the practical prediction method for ship maneuverability of a full-scale ship in the deep water. In this paper, we propose the approximate formula of the interaction coefficient, γ and w R0 , obtained by comparing the predicted maneuvering motion with the measured results of the sea trial for twelve full-scale ships. We confirm the effectiveness of the practical prediction method using the approximate formula of the interaction coefficient for ship maneuverability of a full-scale ship. Though this approach must be validated in many kinds of ship as the next step, it will be expected that this method is very useful for predicting ship maneuvering characteristics at design stage on conventional ship.
