Object and purpose of research. The object of the study is wave-piercing passenger catamarans made of aluminum alloys. The purpose of the study is to find ways and means to improve the design of the bow ends of the catamaran hulls, reduce the complexity of their manufacture and ensure operational safety. Materials and methods. The study is based on the use of ship design methods and numerical calculation methods to predict fatigue strength. Main results. The paper proposes new design and technological solutions for the bow ends of the catamaran hulls, which ensure their high operational safety and reduced manufacturing cost. Conclusion. The results of the research can be used in the rational design of high-performance passenger catamarans.
