The aim of this paper is to provide insight into the sustainable development of nautical tourism and to point out the importance of timely response to sustainability problems in this growing sector of the blue economy. Therefore, the paper specifically explores strategies, policies and initiatives that support sustainable development and create a framework for its implementation. The paper points out the importance of solutions that encourage the use of renewable energy sources, which contributes to reducing the threat to the environment, as one of the most significant challenges of sustainable development. In this way, numerous economic, social and ecological opportunities are opened for the sustainable development of nautical tourism. The transition to a circular economy creates new opportunities for all sectors of the Blue Economy, as well as opportunities to reduce negative impacts on the sea and coasts. Therefore, the paper presents the international environmental program Blue Flag for Beaches and Marinas, which promotes sustainable management of marine resources.
