Summary

A possibility of thrust generation through a utilization of wave power or Wave Devouring Propulsion (WDP) is discussed. Some inventions, observations and investigations related to the possibility have been reported [1–5]. The possibility may be applied not only to increase propulsive efficiency of a ship in waves but also to reduce mean and slowly varying components of wave drift force acting on a moored platform in waves. In the present paper, some experimental results on two basic models are reported. One is a two-dimensional model and the other a three-dimensional one. Some theoretical discussion is also given to the former.
