DNS vs GP Rating: Which Course Is Better for You?
DNS vs GP Rating: Which Course Is Better for You. Choosing a career in the Merchant Navy feels exciting, right? Big ships, global travel, and a salary that makes your relatives suddenly very interested in your life. But before you imagine yourself on the bridge of a massive container ship, there’s a crucial decision to make.
DNS or GP Rating?
This single choice can shape your entire maritime career. Pick wisely, and you’ll sail smoothly. Pick blindly, and you may feel stuck mid-ocean career-wise, of course.
Let’s break this down logically, honestly, and with zero fake hype.
Understanding Careers in the Merchant Navy
The Merchant Navy doesn’t work like a normal 9–5 office job. Ships need leaders and support professionals. That’s where officers and ratings come in.
- DNS trains you to become a Deck Officer.
- GP Rating trains you to work as crew (ratings) in deck and engine departments.
Both are respectable. Both earn well. But they are not the same career ladder.
What Is DNS (Diploma in Nautical Science)?
DNS is a pre-sea training course designed for students who aim to become navigational officers.
Think of DNS as the pilot training program of the sea world.
Eligibility Criteria for DNS
- 10+2 with Physics, Chemistry, and Mathematics
- Minimum 60% aggregate (as per company rule)
- English: Minimum 50% (any one 10th or 12th)
- Age: Usually 17–25 years
- Medically fit as per maritime standards
DNS isn’t for shortcuts. It demands academic discipline and long-term commitment.
Career Path After DNS

Yes, Captain. The one who gives orders, not takes them.
What Is GP Rating?
GP Rating stands for General Purpose Rating. It combines deck crew and engine crew training.
If DNS is the management track, GP Rating is the hands-on technical workforce.
Eligibility Criteria for GP Rating
- Minimum 10th pass

- Medical fitness mandatory
Lower entry barrier, faster entry to sea.

You stay in the rating category, unless you later switch paths through exams and sea time.
