Authors have been making observation on the tidal current and its effect on the ship motion a1Qng Kurushima Strait 、 An appropriate 皿 aneuvering 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 . , aKT 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

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 皿 onitoring splashing sound around bow gives effective information about the transient phenomenon .
