The problem of decarbonization of human activity is one of the most important in the conditions of the ever-increasing threat of global warming. It is solved differently in all areas of modern society, primarily in the fields of engineering and technology. The transport fleet could not be aloof from solving this problem, as it consumes about 6% of the total volume of oil fuel, and the share of greenhouse gases generated during its combustion in ship's internal combustion engines (ICE) is ≈ 3% of their total amount. Therefore, the International Maritime Organization (IMO) in Appendix VI of the Convention "MARPOL 73/78" introduced restrictions on emissions of harmful substances by sea transport. Among the main technical ways to reduce them, the IMO recommends the use of wind and solar energy. Since solar energy systems have small specific power, it is unable to replace ship's ICE. Sailing energy was the main energy on the weasels 150 years ago, so it is potentially able to replace ship diesel engines. A new revival of sailboats began in the 60s of the XX century. At the same time, it is important to choose the right ways and the best options for sailing systems, which allows you to avoid wasting time and money on the development of unproductive options. Therefore, the selection of the TOP-7 best options is an urgent and important task and constitutes the main goal of the work being performed. Its scientific novelty is the substantiation of the best options for modern ships sailing systems and ways of their evolution for the development of recommendations for their design and use. Research methods are based on the comparison of technical and economic indicators of the best ship wind systems of world. Work results. In 2019, Captain Paul Watson highlighted the TOP-7 projects of ship wind systems. In 2022, based on criticism of its shortcomings, a new TOP-7 rating was developed. Its further justification based on the development of new projects of ship wind systems in recent years is given in this work. Conclusions. Modern projects of ship wind systems and their development paths confirm the validity of the new TOP-7 rating, therefore it is recommended for further research and development of ship wind systems.
