Vessels are the ships themselves, while Marine Engineers are professionals responsible for maintaining and repairing the ship's engines and systems. Marine Engineers work primarily onboard vessels or in shipyards, ensuring the vessel's operational safety and efficiency. Both roles require maritime certifications, but Vessels refer to the ships, and Marine Engineers refer to the technical personnel who keep them running.
