The Ship Research Institute is conducting a long-range research project to evaluate present methods of ship structual design and to suggest improvement based on a more realistic knowledge of the loads, stresses, and motions which ships experience in service. Measurement of ship motions, deck longitudinal stresses, web frame stresses and the wave load due to green sea were obtained as one of the series tests in above project on general cargo boat in her service in the North Pacific Ocean during the winter of 1964 and 1965. This report outlines the scope of the tests and presents the data in some detail in order to expedite their use by other investigators. During the entire tests, the maximum magnitudes were estimated 6.5 kg/mm² in tension and 3.8kg/mm² in compression in deck longitudinal stress, between 6.0 kg/mm² and 7.0kg/mm² in transverse web frame and between 2.0 and 4.0 m head in deck wave pressure.
