In this paper, the author propose a simple method to give arbitrary intended motions to floating bodies by wave marker in model basin. In general, when we estimate experimentally the behavior of floating bodies in waves, we generate some intended waves (for example regular waves, irregular waves, transient waves…), and we measure the oscillation motions of the bodies. On the contrary, in this paper, we consider how to give arbitrary intended motions to floating bodies by some control of motion of wave maker. The proposed method is an extension of the method to generate arbitrary waves which have intended time history of water elevation, see reference 1). Our method is very simple and which has no need to perform any numerical calculation. In order to examine this method, model ship experiments were carried out for heave, pitch and roll modes of motion, fairly good agreement was obtained between intended motion and measured one except roll mode motion.
