The Trainee 500 Ton Master Captain is in a training phase working towards full licensing, focusing on gaining practical experience under supervision. In contrast, a Deck Officer is a licensed professional responsible for navigation, safety, and ship operations. While both roles work onboard ships and require similar certifications, the trainee role is preparatory, whereas the deck officer is fully qualified to perform operational duties independently.
