The invention relates to a U-type sail structure which comprises a sail body. The sail body is connected with a sail base through a sail mast. A sectional structure is formed by the cross section of the sail body, and is of a U-shaped structure formed by integrally connecting a pair of body portions, a pair of arch portions and a pair of guide round portions. The body portions, the arch portions and the guide round portions are symmetrically arranged with the rotary axis of a sail as a center. The U-type sail structure is simple, clean and tidy in appearance and high in maximum pneumatic lift coefficient. The maximum lift coefficient of the sectional structure of the sail body can be above 3.0, and is more than 2.3 times that of a common wing type, and the boosting efficiency of the sail can be greatly improved. The aerodynamic force performance optimization design technology is adopted in the sectional structure of the sail body. On the premise of not increasing the complexity of the sail structure, the lift efficiency of the sail is effectively improved through the section line type design of the sail. Compared with a multi-section combined type wing section, the U-type sail structure has the beneficial effect of being simple.
