When a ship encounters waves, it moves bodily and it distorts. The structure being elastic and the waves being random, this behaviour is in the nature of a narrow-band response. A systematic study of linear ship structural dynamics in which this standpoint is adopted was started in University College London about ten years ago and an attempt is made here to explain the present position.
Far from putting a largely unnecessary gloss on traditional techniques of naval architecture, this approach to ship dynamics appears to promise much greater insight into ship behaviour at a time when apparently well found and competently handled ships continue to be lost in the open sea.
