Maritime industry is facing major changes due to macro trends like digitalization, globalization and internationalization, as well as the industry's elevated bureaucratization due implementation of the ISM code and other laws and regulations. These developments have been undergoing for some years and are likely to continue with even higher pace. The maritime industry is a heterogenous industry in terms of operations and vessel types, which leads to the question of how these changes affect the different subgroups of maritime seafarers. Seafarers are traditionally workers with a strong identity, as manifested by the popularity of the term 'good seamanship'. However, research indicate that the notion and interpretation of seamanship is changing. In this study we use a hybrid qualitative-quantitative method to explore differences in what seafarers (N=731) reports as content of good seamanship. The results show that there is a large variation in the semantic content of seamanship, and some notable differences between ages, vessel types and positions on board. In the discussion we make some considerations for practical implications in risk and safety management as well as provide some directions for further research.
