Summary

 
Object and purpose of research. The object of study is small waterplane area twin hull (SWATH) ships whose main advantage is their excellent seaworthiness. The purpose of this work is to demonstrate the broad capabilities of such vessels
Subject matter and methods.The knowledge from foreign literature along with the author’s data are employed. Comparison methods focus on the main specific features of the technology for different fields of application. Main results. Brief review of the SWATH background is given highlighting the main trends of development. Common features and differences of each SWATH type is identified. The revealed merits and disadvantages, design details point to a broad range of possible applications.

Conclusion. SWATH architecture may provide a considerable improvement in seaworthiness of small and medium displacement vessels. SWATH is an economically viable option for all types of marine vessels with a relatively large deck area, so-called capacity carriers, like passenger, research, ro-ro, naval ships, etc. For more efficient application it is recommended that alternative SWATH projects should be developed at an early design of vessels for the above missions.
