Abstract

In theory, a small water-plane area results in a larger than usual immersion of the main displacement volume of a ship’s hull(s).Although practical realization of this theory typically involves an unusually large draft, small vessels tend to have small enough drafts. This contradiction demonstrates the problem associated with a minimal-sized ship with a small water-plane area (SWA ships). Here restrictions in terms of possible displacement and dimensions are described, with the range of minimal displacement and dimensions of an SWA ship estimated and alternative options outlined on the base of [1], [2], [3], [4]. (A SWA hull consists of an under-water gondola as the main displacement volume,together with one or more struts connecting the gondola to the above-water platform. Evidently, the struts intersect the watersurface at design draft.).

Abstract

A brief history of the expanded application of multi-hull ships and boats is shown. The possibilities of catamaran development are proposed. The first line of multi-hull development is the wider use of various types of multi-hulls. The second line of development is a special method of designing, including complex comparison of seaworthiness. The proposed method ensures the elimination of the disadvantages of multi-hulls, and the fullest realization of their advantages. Practical examples of the developments are shown.
