The Ship forms, especially those of small fishing vessels are to be determined from the point of view not only of propulsive performance but also of dynamical properties on the ocean. As the first step in the direction of researches, the author has performed the resistance -& rolling-tests about the 5 ship forms (a steel ship type, a wooden ship type & 3 intermediate types) of small seine-fishing vessels. This paper is reported about the results of these tests.
