This study investigated the service quality of maritime police officers as viewed by coastal inhabitants of Pagadian City, Zamboanga del Sur, and their link to their work performance over the calendar years 2022 to 2023. Employing a descriptive-correlational research approach, the study involved 22 maritime police officers and 80 coastal inhabitants as respondents. Data were analyzed using Frequency and Percentage, Weighted Mean, Mann-Whitney U Test, and Pearson Product-Moment Correlation Coefficient. Results revealed that marine police personnel demonstrated a very satisfactory level of performance. A substantial association was established between the perceived service quality and the work performance of the officers. The mean service quality rating was 3.99, whereas the mean performance rating was 4.09, with a mean difference of 0.10. These findings imply that greater service quality ratings are associated with better performance outcomes, underlining the crucial importance of service quality in boosting maritime law enforcement efficacy.
