On this website Jelle van Lottum and Lodewijk Petram showcase the results of their research into the functioning of maritime labour markets and the characteristics of the seagoing workforce, and the changes these underwent over time. Theye are interested in question such as: how did skill levels of seamen develop over the centuries? How international was the maritime sector? And what changes in the level of internationalisation do we witness over time? What differences can we observe between careers of native and migrant sailors?
