The goal of this thesis titled "Possibility of e-services and nautical tourism" was to develop a proposal for an overview of e-services and Internet information in the Republic of Croatia based on available information. The Republic of Croatia shows a significant share of nautical tourism in the overall functioning of its own economic system. Different scientific research methods were used in the preparation of this thesis. They were applied to the studied bibliography. The bibliography was based on legal regulations or in the works of certain authors. The studied matter itself was systematized. Then it was analyzed, after which the knowledge gained was presented in short. The paper was written in a systematic approach, and it is necessary to emphasize the applied forensic approach to the researched issue. Also, given the particularity of the research problem, the applied empirical approach was utilized. The achieved research results show the existence of various services in nautical tourism in the part of e-services and Internet information. The paper also proposes a method of collecting and classifying e-services, as well as Internet services in nautical tourism. The conclusions in this paper indicate the limitations of the conducted research, as well as the need for further research, especially due to the fact that e-services and Internet information are collected and distributed in a system that is extremely dynamic, and as such represents an extremely variable system.
