Methods and means to improve seakeeping performance and comfort and to reduce material consumption of passenger catamaran

Abstract

Object and purpose of research. This paper discusses passenger catamarans. Its purpose is to find methods and means to improve seakeeping and propulsion performance in waves, reduce external structural loads, improve comfort and reduce material consumption of catamaran by means of optimally shaped bows and passive motion stabilizers. Materials and methods. The study is based on the methods of ship theory and ship motions, as well as on numerical calculation methods. Main results. Based on the calculation data analysis, this paper suggests principal technical solutions offering high comfort and cost-effectiveness of catamaran. Conclusion. These results could be used for design optimization of comfortable and efficient passenger catamarans.
