Although the history of nautical tourism cannot be defined precisely, it can be connected to the history of sailing and navigation dating all the way back to the ancient times. The popularity and current growth of nautical tourism indicate a great demand in the Mediterranean, which in turn reveals Croatia's significance on that particular market. Geographic location, temperate climate, safety and a beautiful coastline with a myriad of islands, reefs, unique bays and beaches are all factors indicating that Croatia is an ideal destination for developing and ameliorating nautical tourism. In addition, this paper puts particular emphasis on the city of Rijeka, as it offers a unique cultural and historical heritage, as well as interesting content for tourists. It is also the perfect place in Croatia to create a new and innovative marina that would provide a unique experience and leisure for passionate nautical tourists. Nautical tourism is not described in detail and there are no limits nor quality levels it shout meet; yet, the statistical comparison of successful cities with Croatia clearly shows what conditions need to be amended, created and improved in order to satisfy potential new visitors and increase the number of tourists in an attractive Mediterranean destination. The purpose of this paper is to point out the shortcomings currently present in the industry of nautical tourism in Croatia and to suggest ways to improve it, i.e., to contribute with innovative ideas related to the new concept of nautical tourism. The project of creating a marina in Rijeka, along with the concept of new ideas and examples of the leading nautical destinations in Europe, such as Barcelona and Monaco, all indicate the possibility of an unprecedented development of nautical tourism in one destination, which would then follow throughout Croatia. A high-quality nautical offer might result in a new level of tourism in Croatia and increase its competitiveness in the Mediterranean tourism market.
