Oarsmen as trained combat power

A galley's rowers were skilled combat personnel rather than interchangeable labour. Hundreds had to work together to build speed, manage heavy oars through difficult turns, and strike at an angle that damaged the enemy without trapping their own ram. They needed sustained training and enough food for strenuous rowing. If enslaved people entered these crews, one proposed interpretation is that they served as free men aboard ship or earned freedom by completing their service. Roman citizenship brought voting rights and legal protections, giving recruits a powerful incentive to remain loyal. Training, food, motivation, legal status, and retention were therefore operational requirements as well as social questions.
