Abstract : For practical application, the problem of mathematical ship surface was subdivided into two portions: (1) To approximate a given hull form mathematically by a surface equation; and (2) to modify a ship surface equation to obtain the desired changes in hull characteristics from one design to another. For the case of a single-screw, flat-bottom, merchant-ship hull form, a procedure of obtaining a surface equation to fair and to interpolate a given table of offsets was developed. This equation will give not only the waterlines and stations but also the end profile. The numerical computation of such a procedure was programmed into a high-speed electronic computer. From a given table of offsets, any number of waterlines and stations may be computed. The second portion of the work is not included. (Author)
