The paper analyses marine accidents in the area under the jurisdiction of the Harbourmaster's Office Zadar. This research examines the categories of events, types of vessels, and the chronological distribution of accidents. Marine accident analysis has revealed a high incidence rate involving boats, predominantly in summer, and has highlighted several high-risk areas. The paper aims to identify the most common types of marine accidents and the times of year when they are most likely to occur. Furthermore, this paper proposes preventive measures to re-duce the risk of marine accidents and to enhance navigational safety. The recommendations in-clude fostering cooperation between the Vessel Traffic Service and the masters, deploying smart cameras, providing maritime traffic safety education, implementing regular data collection proce-dures, prohibiting autopilot use in coastal waters, installing psychological floating barriers at des-ignated swimming areas, and increasing the frequency of inspections during the summer months. The authors suggest implementing preventive measures in high-risk areas, like Mali Ždrelac and Mala Proversa.

The specific features of various ports create difficulties for county port authorities in Zadar County and other coastal regions of Croatia in effectively performing daily tasks like managing, maintaining, constructing, and operating ports. The reason for this is the increased presence of various elements that directly affect decision-making regarding the port's progress. Therefore, it has been acknowledged that it is necessary to establish a methodology that allows decision-makers (county port authorities) to make objective decisions regarding the future direction of port development. This article presents a methodology proposal based on the AHP (Analytical Hierarchy Process) method of multi-criteria decision-making. When determining the methodology, special attention was paid to the decision-makers, who were found to possess specific professional knowledge in their activity but rarely possess prior expertise in multi-criteria decision-making. Hence, it was crucial to establish a methodology that would be both straightforward and suitable for adoption by decision-makers themselves. The AHP method, aided by a wide range of easily accessible and even cost-free tools, facilitates this through its visual representation of goals, criteria, sub-criteria, interconnections, and subsequent outcomes. This approach ensures the feasibility of ongoing monitoring throughout the decision-making process. Ultimately, the proposed methodology was verified on the examples of five port areas based on conducted empirical research, which, with their properties, satisfy different directions of development. At the same time, the obtained results confirm its applicability.
