TL;DR: In this article, a standard series approach to the trend determination problem of ship seakeeping variables is presented, which involves construction of an extensive data base and interpolation over a selected subset thereof for each specific problem.
Abstract: Seakeeping can be rationally included in the ship design process. The prerequisite is determination of trends in seakeeping variables with changes in hull geometry at an early stage in the design process. This paper outlines a standard series approach to the trend determination problem. It involves construction of an extensive data base and interpolation over a selected subset thereof for each specific problem. Application is made to single-screw cargo hulls without large bulbs operating in directly ahead seas. The resulting predictions are found to be satisfactory. They indicate that an effective design tool has been developed. This tool is available to the profession through the Naval Ship Research and Development Center.

TL;DR: It is shown that the designer must design and not let his principal tool drive him to the wrong end in the design procedure.
Abstract: The computer is a powerful aid to the designer and has made possible engineering design which would have been considered impossible only a decade or so ago. However it has not changed the design process but enhanced it in many ways. The author believes that the skill in using the computer as a design tool stems from knowing where it fits into the design procedure, and in this paper shows that the designer must design and not let his principal tool drive him to the wrong end.
