The design of interior decoration themes in cruise ships is crucial for the overall orientation and conception of the product, and it affects the whole process of aesthetic design including the promotion of cruise products, appearance design, functional organization and interior decoration style in the later stages. Therefore, on the premise of meeting the aesthetic needs of passengers and consumers, this paper studies the design principles and aesthetic design strategies of interior decoration themes.

Based on an investigation of the theme styles and aesthetic design characteristics of 40 popular cruise ships in the international market, the theme tendencies of international cruise ships are analyzed, and the principles and methods of theme planning and aesthetic design are summarized and discussed. Based on the elements of each space in the cruise ship, the correlation between interior theme design and aesthetic design is studied, and the design methods of the interior space and decoration of cruise ships are explored.

On this basis, the transformation of a thematic conceptual scheme into a realized functional layout and interior decoration can be implemented in the interior decoration of cruise ships.

This study provides substantial references for the basis, ideas and practices of aesthetic design in the overall design of medium-large cruise ships.
