'Falnes and Kurnianwan investigate thoroughly and comprehensively, using robust analysis tools, a very important sector of modern technology – namely how bodies oscillate subjected to ocean waves. The content of the book covers the entire area between standard configurations up to the sophisticated wave energy conversion systems. The book is indeed a valuable tool that will be treasured by students, researchers and the water wave community at large.' Ioannis K. Chatjigeorgiou, National Technical University of Athens
