Safety leadership is critical in high-risk industries such as shipping since inadequate leadership can cause marine accidents, resulting in injuries, fatalities, damage to property and environmental pollution. One of the aspects of good and effective safety leadership is creating good human relations and satisfaction among crewmembers, considered a precondition for effective teamwork. Officers on board ships should establish effective teamwork and implement adequate safety leadership, positively affecting safety culture, increasing safety in general and improving marine environment protection. Safety leadership onboard ships comprises several characteristics, including maintaining safe work performance, carrying out safety training, and encouraging crewmember morale. Therefore, it is essential for all stakeholders in shipping industries that officers onboard ships can identify those characteristics, adapt, and apply them adequately. This paper presents the characteristics and skills that shipboard officers need to apply in order to be excellent leaders and serve with adequate safety leadership abilities. One tool for recognizing those characteristics and skills was a survey carried out among experienced professional seafarers. Analysis of the survey data revealed latent factors, these being transformational and transactional leadership elements affecting safety leadership onboard ships.
