The present paper describes the hydraulic performance of a newly developed floating breakwater in regular waves. Laboratory tests were conducted with the aim of determining the wave transmission, reflection and energy dissipation characteristics of the breakwater model under various wave conditions. A comparison of wave attenuation ability between the present breakwater and other breakwater designs with similar geometrical criteria has been made. In addition, wave interactions with the breakwater are also explored with respect to the effect of wave steepness and water depth.
