The authors established a measurement system which collects the data of the attitude and movement of a full-scale sailing boat in conjunction with the data of wind and wave, simultaneously. This system was confirmed by the sea test of the sailing cruiser, 10.6m-LOA, under various wind and wave conditions. The both angles of heel and pitch of the boat were measured using a vertical gyro, which was purchased by the budget of the Grant-in-Aid for Scientific Research.The results obtained are as follows :1) The measured items at the steady sailing states were compared with the results of the velocity prediction program (VPP), which was calculated using the data of both model tests and numerical analysis. The comparison clarified some controversial points of the VPP, and then those points were improved.2) The movement of the boat was measured in conjunction with wave measurements using a throw-in type wave meter. The measured results were analyzed by means of spectral analysis, and the results were compared with both model test data and numerical calculations. The analyzed results indicated the distinctive feature of motion for the sailing cruiser in waves.3) The steering and maneuvering characteristics of the boat were also investigated. The performed experiments were normal steering, Z maneuver, luffing-up and tacking tests. The test results were compared with those of numerical simulations. The comparison provided important informations for the prediction of maneuvering characteristics and tacking performance of a sailing cruiser.The method of performance prediction for a sailing cruiser including dynamic characteristics was established by this study. These results can be used as a foundation for the research to develop high performance sailing cruiser and intelligent steering system for sailing.

建立了一套测量系统，该系统能同时采集实船的姿态、运动数据和风浪数据。该系统已通过10. 6 m-LOA帆船在各种风浪条件下的海上试验得到验证。利用科研资助预算购置的垂直陀螺仪对该艇的横倾角和纵摇角进行了测量，获得了如下结果：1）将定常航行状态下的测量项目与速度预报程序（VPP）的计算结果进行了比较。通过比较，澄清了VPP中存在的一些争议，并对这些问题进行了改进。2）使用投入式波浪计测量了船的运动和波浪测量。对实测结果进行了频谱分析，并与模型试验和数值计算结果进行了比较。分析结果显示了该型帆船在波浪中的运动特点。3）研究了该型帆船的操纵和操纵特性。所进行的试验包括正常转向、Z机动、俯仰和跟踪试验。将试验结果与数值模拟结果进行了比较。通过比较，为帆船的操纵性能和航向性能的预报提供了重要信息，建立了考虑动力特性的帆船性能预报方法。研究结果可为高性能航海巡洋舰和航海智能操舵系统的研制提供依据。
