Tourism represents one of the most dynamic economic activities, encompassing various interactions and events that occur when tourists come into contact with a tourist destination. Tourism holds an exceptionally important place in economic development and is the leading sector of the Croatian economy. Sustainable development, as a concept, refers to a form of development that meets the current needs of society while considering the needs of future generations. The key feature of sustainable development is achieving a balance between social, economic, and environmental aspects. Sustainable tourism particularly emphasizes this balance, providing benefits by generating profit while simultaneously preserving the environment. Sustainable tourism has a positive impact on the local community, promotes social justice, protects natural, cultural, and historical heritage, cares for the environment, and uses resources rationally. Integrated Coastal Zone Management (ICZM) is a continuous process aimed at achieving sustainable development of coastal areas and preserving their biological diversity. The main purpose of ICZM is to mitigate all threats arising from unsustainable development practices and promote sustainable tourism. Nautical tourism is a form of tourism focused on activities related to boats and navigation. This includes cruising, sailing, fishing, diving, and staying on water surfaces such as seas, lakes, and rivers. Nautical tourism attracts people who enjoy maritime adventures, exploring islands and coastlines, and relaxing on the water, with destinations like Croatia being well-known for their popularity among sailors.
