Calculation of Turning Ship Derivatives in Shallow Water

By Shösuke INOUE

Kji MURAYAMA

Abstract

The derivatives of forces acting on a turning ship in deep water are able to calculate by the analogy of the low aspect ratio wing theory and we think Kárrnán-Bollay's wing theory agrees well with experimental values. In this paper the derivatives of forces in shallow

water by Bollay's wing theory asumuption are numerincally computed using infinite images

and by the ratio of derivatives in shallow water and in deep water, derivatives of ship
