抄録

Authors have been making observation on the tidal current and its effect on the ship motion along Kurushima Strait. An appropriate maneuvering control is essential for the safety navigation under a strong current condition. The ship maneuvering motion was analyzed using a simple response model, i.e., a KT model. Although the difference between an estimated motion by the KT model and the actual motion shows the effect of the current, a strong transient phenomenon, a side slip motion of the ship, was observed especially in entering the strongest part of the current. As the detection of the side slip is essential for the ship control, a continuous watch on water surface in front of the ship and monitoring splashing sound around bow gives effective information about the transient phenomenon.
