Introduction

If you want to join the Merchant Navy after 12th, the usual pathway is to choose an eligible maritime course, meet the required academic and medical criteria, complete the applicable entrance/admission process, and pursue the required training. For deck-side careers, students commonly consider courses such as Diploma in Nautical Science (DNS) and B.Sc. Nautical Science, while Marine Engineering is the relevant route for engine-side careers.

The exact eligibility, entrance-exam and admission requirements can vary by course and admission cycle, so students should verify the latest official requirements before applying.

What Is the Merchant Navy?

The Merchant Navy is the commercial shipping industry responsible for transporting cargo, oil, gas, and passengers across international waters. It is different from the Indian Navy and offers civilian jobs on merchant ships.

The Merchant Navy is the commercial shipping sector that transports goods and essential cargo by sea between countries. Merchant ships carry commodities such as crude oil, petroleum products, LNG, containers, automobiles and other cargo across international routes.

The Merchant Navy is different from the Indian Navy, which is a military force responsible for maritime defence. Merchant Navy professionals work in the commercial shipping industry and may serve in deck, engine or other onboard roles.

For students planning to join the Merchant Navy after 12th, the two main career areas are the Deck Department and Engine Department. The course and career route you choose depends on whether you want to work in navigation and ship operations or in marine engineering and machinery.

Departments in the Merchant Navy

The Merchant Navy broadly includes different onboard roles and departments. For students entering after Class 12, the two main career routes are the Deck Department and Engine Department.

1. Deck Department
The Deck Department is responsible for navigation, ship operations, safety, cargo operations and related duties. A typical officer career progresses from Deck Cadet → Third Officer → Second Officer → Chief Officer → Master/Captain, subject to the required sea service, examinations and certificates.

2. Engine Department
The Engine Department manages the ship’s engines, machinery, electrical and technical systems. A typical engineering career progresses through ranks such as Junior/Training Engineer → Fourth Engineer → Third Engineer → Second Engineer → Chief Engineer, subject to the applicable training, sea service and certification requirements.

3. Ratings and Other Shipboard Roles
Merchant ships also have ratings and support roles, depending on the vessel and department. These can include GP Rating and other specialised positions. The eligibility and training route for these roles is different from the officer-entry routes discussed in this guide.

For students after 12th, choosing the right course first is important because the course determines the career route you enter.

Merchant Navy After 12th – Eligibility

Students who want to join the Merchant Navy after Class 12 generally need to meet academic, age, medical and course-specific requirements. The exact eligibility depends on the course and admission year, so candidates should always check the latest requirements before applying.

Educational Qualification

For common officer-entry courses such as DNS and B.Sc. Nautical Science:
• 10+2/equivalent with Physics, Chemistry and Mathematics (PCM)
• Minimum 60% average in PCM

• Minimum 50% in English

•  

Age Limit

Age requirements for Merchant Navy courses depend on the course, category and applicable admission rules. For example, the IMU 2026–27 prospectus specifies different maximum-age limits for the DNS programme based on gender and reservation category. Therefore, students should check the latest prospectus of the course they are applying for rather than assuming a single age limit for all Merchant Navy courses.

Medical Fitness and Eyesight Requirements

Medical fitness is an important requirement for students entering Merchant Navy training. Candidates must meet the applicable Directorate General of Shipping (DG Shipping) medical standards and undergo examination by an approved medical examiner.

Eyesight and colour-vision requirements can vary according to the department. For example, the current DG Shipping pre-sea standards specify different distance-vision requirements for Deck and Engine departments, along with normal colour vision requirements.

Do not rely only on an online eyesight test. Candidates should complete the required medical examination with an approved medical examiner before making major course or admission decisions.

Meeting eligibility is the first step to understanding how to join Merchant Navy after 12th.
