The lateral forces on each of the segments were measured for various ship hulls including a flat plate. Here, it is assumed that lateral force on each segment can be expressed by a formula consisting of linear and second order terms. The linear and nonlinear derivatives are determined from the curve-fitting by a least-squares method. This report gives experimental results of the distribution of the nonlinear lateral force component over the ship's length. A comparison is made between local values of second order derivatives and cross-flow dlag coefficients at a drift angle of 90°. As a result, it is indicated that a ratio of the two values is a function of the longitudinal location. Moreover, distribution of the ratio is greatly dependent on the ship's hull form. In predicting the nonlinear derivative with sufficient accuracy, the cross-flow drag coefficients for 90°drifting should be corrected when s ship moves obliquely. Development of prediction procedure of the correction factor is left as a futule problem., rights: 社団法人日本船舶海洋工学会協会
