If you are planning a career in the Merchant Navy, one of the first things to check is whether you meet the required educational, age, eyesight and medical standards. The eligibility rules are different for students entering after Class 10 and those applying after Class 12.
In India, maritime education and training are regulated by the Directorate General of Shipping (DG Shipping), while the Indian Maritime University (IMU) conducts admissions for several major undergraduate maritime programmes. Therefore, candidates should always check the latest official requirements before paying any training or admission fee.
What Is the Merchant Navy?
The Merchant Navy is the commercial shipping sector that operates cargo ships, container vessels, tankers, passenger vessels and other merchant ships. Careers are available in areas such as deck operations, marine engineering, electrical work and shipboard ratings.
The entry route depends mainly on your educational qualification.
A student who has completed Class 10 can look at certain rating-level maritime training courses, while candidates with Class 12 PCM can apply for officer-oriented programmes such as B.Sc Nautical Science, Diploma in Nautical Science (DNS) and B.Tech Marine Engineering, subject to the respective course requirements.
Merchant Navy Eligibility After 10th
Students who want to enter the Merchant Navy after Class 10 generally need to look at approved pre-sea rating courses rather than directly entering officer-level degree programmes.
For example, the DG Shipping requirements for the GP Rating course include Class 10 qualification with English, Mathematics and Science, along with the prescribed minimum marks. The revised GP Rating training circular specifies 40% aggregate marks and 40% in English at Class 10/Class 12 level, depending on the entry route. It also specifies physical standards under the applicable medical rules.
Basic route after Class 10
| Requirement | General information |
| Qualification | Class 10 from a recognised board |
| Subjects | English, Mathematics and Science for GP Rating route |
| Marks | 40% aggregate; English requirement also applies |
| Age | Course-specific; check current DGS rules |
| Medical | Must meet DG Shipping medical standards |
| Training | DGS-approved maritime training institute |
Candidates should not select an institute only because it advertises “Merchant Navy admission.” Always verify whether the course and institute are approved by DG Shipping.
Merchant Navy Eligibility After 12th
Class 12 students have more options, particularly if they have studied Physics, Chemistry and Mathematics (PCM).
For programmes such as B.Sc Nautical Science, DNS and Marine Engineering, the current IMU requirements generally include 60% aggregate in PCM and at least 50% in English. The exact conditions can vary by programme and admission year.
For example, the 2026–27 IMU prospectus states that B.Sc Nautical Science requires 10+2/equivalent with a minimum 60% PCM average and 50% English in Class 10 or 12, along with the applicable age, medical and admission requirements.
Important Class 12 subjects
For officer-level technical and nautical programmes, PCM is particularly important. Marine Engineering programmes, for example, require Physics, Chemistry and Mathematics at 10+2 level, with the prescribed marks in PCM and English.
Merchant Navy Age Limit
There is no single age limit for every Merchant Navy job. The age requirement depends on the course, institute and admission rules.
For several IMU undergraduate programmes, the 2026–27 prospectus gives maximum ages based on category and gender. For B.Sc Nautical Science, for example, the maximum age is listed as 25 years for General-category male candidates, with higher limits for specified reserved categories and female candidates.
For GP Rating, the DGS revised course standards specify a minimum age of 17½ years and maximum age of 25 years at commencement of the course, with applicable provisions for relaxation.
Because age rules can be amended, candidates should check the current DGS circular and the institute’s admission notification before applying.
Merchant Navy Eyesight Requirements
Eyesight is an important part of Merchant Navy eligibility, particularly for candidates seeking deck or engineering careers at sea.
The medical examination includes assessment of visual acuity and colour vision. DG Shipping’s medical rules refer to STCW eyesight standards and require seafarers to meet the applicable visual standards. The current medical guidance states that seafarers should achieve the prescribed minimum unaided eyesight standard and that colour vision is tested using recognised methods such as Ishihara or equivalent testing.
Wearing spectacles does not automatically mean that a candidate cannot pursue a maritime career. However, the permissible eyesight standard depends on the job and applicable medical category.
Candidates should therefore get an eye examination from a DG Shipping-approved medical examiner instead of relying on informal eyesight tests.
Merchant Navy Medical Requirements
Medical fitness is not simply a formality. A candidate must be physically fit to perform duties safely onboard a ship.
The DG Shipping medical framework covers areas including eyesight, physical ability and other health examinations. The applicable pre-sea and in-service standards are linked to the STCW requirements.
A medical examination can include:
- Eyesight and colour vision
- Hearing assessment
- General physical fitness
- Relevant laboratory investigations
- Assessment of physical ability
- Medical conditions that may affect safe work at sea
The final decision is made by the authorised medical examiner according to the applicable standards.
Merchant Navy Admission: Important Official Portals
| Purpose | Official Portal/Source |
| DG Shipping regulations and notices | Directorate General of Shipping |
| IMU admissions | Indian Maritime University Admissions |
| IMU 2026–27 admission updates | IMU Admissions 2026–27 |
| Maritime training information | DGS Training Circulars and Guidelines |
IMU’s 2026 admission page lists notifications for B.Tech, B.Sc and DNS programmes, including IMU-CET results, counselling and admission lists.
Important Things to Check Before Joining
Before paying fees to a Merchant Navy training institute, candidates should verify:
- Whether the institute is approved by DG Shipping.
- Whether the specific course is currently approved.
- Whether you satisfy the latest age and academic requirements.
- Whether you have cleared the required medical examination.
- Whether the admission is through IMU-CET, institute admission or another prescribed route.
- Whether the institute has clearly provided its fee structure and admission conditions.
DG Shipping itself has highlighted the risk of aspiring seafarers being misled by fraudulent agents and false promises.
Merchant Navy Eligibility: 10th vs 12th
The easiest way to understand the difference is this:
After 10th: Candidates can explore eligible rating-level maritime training such as GP Rating, subject to the current DGS requirements.
After 12th PCM: Candidates can pursue more advanced nautical and engineering pathways such as B.Sc Nautical Science, DNS and B.Tech Marine Engineering, provided they meet the prescribed marks, age, medical and entrance requirements.
Therefore, students who have completed Class 12 with PCM have access to a wider range of officer-training pathways.
Final Checklist for Merchant Navy Aspirants
Before starting your Merchant Navy journey, keep your Class 10/12 certificates, identity documents and other required records ready. Most importantly, complete your medical examination through the authorised channel and verify the training institute through official sources.
Eligibility requirements can change through new DG Shipping circulars or annual admission prospectuses. For the 2026 admission cycle, candidates should rely on the latest DGS and IMU notifications rather than old eligibility information circulating on social media or private websites.
