HYDRODYNAMICS AND SHIP PERFORMANCE

Ship hydrodynamics is the study of what happens where the ship's hull meets the water. Markets, industries and politics are man-made influences which will have changed by the 1980s, doubtless with visible effects upon the inboard and upper parts of ships. Ocean wave spectra, chart soundings and the physical properties of water are, on the other hand, fixed quantities; the hydrodynamicist is fortunate in that his principal constraints are set not by legislators but by nature, which is more predictable, and so the wet part of the hull will not be so very different in the eighties from the hulls we have known in the sixties and seventies. In discussing hydrodynamics, changes which may well be important but which are unlikely to be spectacular are included. (Author)
