The central concern of the study is the leadership styles used by the shipboard officers and its relationship to their selfefficacy in governing their bounded human resources. This problem was raised because it is uncertain whether shipboard officers are able to move their people towards the attainment of their established goals. This study used a descriptive and correlational method with 101 Shipboard officers who has just embarked within 2009-2016 as their last contract of employment in working abroad. According to the data collected, there are no significant differences in the level of self-efficacy of the shipboard officers when classified according to age, position, area and span of control except the number of years as a shipboard officer. In conclusion, there is a strong relationship between the leadership styles and self-efficacy of shipboard officers. Their understanding of their own capabilities can affect the leadership style that they adopt. Their concept plus the attitude and behaviour they demonstrate can reflect what type of a leader they are.
