Hello Anish,

Hope you are doing good!

Specifically, for joining or working at ship, there are 3 classified departments: Engineering, Navigation & Ratings. For Ratings, minimum qualification requirement is 10th (Secondary Education). So, you can join in Rating department without PCM .

But to join merchant navy as captain You should have at least four GCSEs (grades A-C), or equivalent qualifications . These should include English, maths and physics (or combined science).

Hope it helps.

Thankyou
