This thesis explores the needs of additional education and specialization that would be in line with new trends and contribute to the creation of an offer of additional content for the charter segment of nautical tourism products in the Republic of Croatia. Nautical tourism is one of the most profitable and promising forms of tourism that are developing in Croatia, and it is important to network it with other special forms of tourism with the purpose to create adventure routes and itineraries for boaters. Boaters are tourists with higher spending power and are looking for an experience offering in nautical destinations that is in line with new trends but also at a high ecological level. Therefore, this paper proposes an attraction basis that is essential for connecting nautical tourism with tourism of special interests. The paper uses the analysis of relevant professional and scientific literature, and for the empirical part, the analysis and interpretation of data collected by the interview method is given. A special contribution is the proposal of education for the interpretation of maritime heritage through the method of storytelling, which is important for skippers and employees in marinas. It is the basis for brand communication and differentiation, and it is important to point out that through additional education, the importance of authenticity and identity of the Adriatic maritime space will be emphasized.
