Entrepreneurship is a fundamental part of any national economy. In sea-related economies, entrepreneurship is developed using the maritime resource. In the case of Croatia, tourism, and in its component nautical tourism, are extremely important for the regional and local economy, its survival and development. Given the importance of nautical tourism, especially the marina business and all activities related to marinas, including charter, authors have conducted several studies including this one. As shown by the SWOT (Strengths, Weaknesses, Opportunities, and Threats) analysis, which was conducted during the development of the first strategy for the development of nautical tourism (2006), the conditions and circumstances of Croatian coastal sites, which relate to the marina business, differ significantly from north to south. The objective of this research was, considering the difference in development of these localities, to investigate
and to compare Croatian and German model of using sea as a resource. The aim was to answer the question why Croatian entrepreneurship is significantly less developed than Germany, at least in the part of the state-entrepreneurship relationship. Besides desk research, method of analysis was used to investigate that problem, as well as method of comparison. Business data, as well as other detailed information, was collected in collaboration with Kroeslin marina (Germany). Besides that, two German laws that come as a result of the German model were analysed. To conclude on the performance of the Croatian model which uses only concession model, criterion comparison of German and Croatian model was made. In this way interesting results were obtained. Based on these research results, it was concluded that Croatia still does not have a developed model and system for the use of resources, the sea, which would support the development of marinas, as well as entrepreneurship in general. Therefore, cooperation with Germany, as well as with other developed EU economies, is of special importance for the development of the Croatian economy.
