Beyond technical proficiency, seafarers must develop strong leadership qualities to navigate complex roles effectively. This study examines the impact of leadership skills on the adaptability and performance of alumni student leaders from the Asian Institute of Maritime Studies (AIMS). The quantitative research focused on 40 respondents from BSMT and BSMARE courses at AIMS, who served as leaders between 2017 and 2022 and gained onboard experience. Data were collected using a self-designed survey with a five-point Likert scale, distributed via Google Forms. Findings revealed strong agreement among participants that leadership skills significantly enhance adaptability and performance in maritime roles. Specifically, these skills improved competency, decision-making, and efficiency, while fostering adaptability in diverse work environments, effective relationship management, and resilience in challenging situations. The study also found no significant differences in perceptions across different respondent profiles, highlighting the consistent positive impact of leadership skills. These results underscore the importance of cultivating leadership abilities in maritime education, as they are crucial for career success and contribute to the overall efficiency of crews and vessels.
