Ship UV form variation under limiting constraint

The key of ship UV form variation is to find out the transformed function given by some boundary conditions in three dimensions. Using the variation function, a series of hulls with different UV form and the same section area curve can be produced by a selected parent ship form. It can be seen that the new approaching method is very reliable and practicable by giving some examples of the real hull UV variation under the limiting constraint, so it can be offered to the practical use of ship lines design.
