1. The resistance test, the propeller open-water test and the self-propulsion test were carried out using Wigley hull, propeller and rudder models in Kyushu Univ. We could grasp the fluctuation of the propulsion factors due to the free surface effect.2. The wake distributions at the propeller plane were calculated by using the boundary layer theory at Yokohama National Univ. and Hiroshima Univ.3. The computer code to calculate the propulsive performance of the Wigley ship was completed by the group of Kyushu Univ. Calculations using this code and input data 2 showed good agreement with experimental results 1.4. By using the finite difference method, the wave profiles and pressure distributions were computed around the ship bow advancing in still water and in Head seas at Univ. of Tokyo.5. The boundary element method to calculate the nonlinear sloshing was developed at kyushu univ.6. The propulsive performance of the Wigley ship and the series 60 ship in regular head seas were calculated at Kyushu Univ. and compared with experiments.

1. 利用九州大学的Wigley船体模型、螺旋桨模型和方向舵模型进行了阻力试验、螺旋桨开水试验和自推进试验，掌握了自由水面效应对推进系数的影响。在横滨国立大学和广岛大学用边界层理论计算了螺旋桨平面的尾流分布。计算Wigley船推进性能的计算机代码是由九州大学的研究组完成的。使用该代码和输入数据2进行的计算与实验结果一致。利用有限差分法，计算了东京大学船舶艏部在静水中和首海推进时的波浪剖面和压力分布。计算非线性晃动的边界元方法是九州大学发展起来的。在九州大学对威格利船和60系列船在常规首海的推进性能进行了计算，并与实验进行了比较。
