In this paper, the wave deformation by and the wave force acting on three large circular cylinders are examined experimentally and theoretically, in relation to the case of one- and two cylinders. The wave profile around the cylinders and the wave force acting on them vary, according to the incident wave height, period and propagation direction, and the distance of the cylinders, and they are quite diffrent from the cases of one or two cylinders. The wave deformation and the wave force are shown to be well predicted theoretically by diffraction theory based on the boundary integral method using a vertical line wave source Green's function.
