Based on the first sail training ship proposed by China, this paper designs the public space inside the ship. Through the internal design of the cabin, we will try our best to improve all kinds of behavior conditions in the ship, improve the quality of the internal environment in the ship, and provide a good reception environment for heads of state, senior naval officers and visiting public.

According to the design function of the cabin of the training ship, the interior design of the meeting room, small meeting room, dining room and meeting room, corridor and passage for senior officers is carried out. As a ship to receive the head of state's visit, the design should fully display the characteristics of China. The traditional elements of China should be used in the design, and the decoration should reflect the style of China navy and the international image of China.

Main work: Firstly, the domestic and foreign ship cabins are studied, and the living environment of the ship is analyzed and designed to determine the subject. Secondly, according to the relevant information about ship cabins such as ship outfitting, ship architectural aesthetics and ergonomics, combined with the basic theoretical knowledge of the cabin, the cabin environment is compared and analyzed, and the optimization scheme is designed. Finally, the comprehensive display is designed by using related software.
