After 10th, you can apply for Merchant Navy through the GP Rating (General Purpose Rating) course, a 6-month course which is approved by DG Shipping, which enables you to work on ships as a rating. After 12th with Physics, Chemistry and Maths (PCM), you can opt for officer level positions through B.Sc Nautical Sci or Diploma in Nautical Sci (DNS) or B.Tech Marine Engineering. Most of these options require you to smile through an entrance exam such as the IMU CET, clear a medical and complete the admission process at a DG Shipping-approved institute.
If you wish to join the Merchant Navy but do not know from where to begin, this guide covers every means step by step. You will find out about eligibility, courses, exam preparation, documents, salary as well as mistakes to avoid.
What Is Merchant Navy?
The merchant navy comprises commercial vessels engaged in transporting cargo and passengers on the sea. These are oil tankers, container ships, bulk carriers, chemical tankers, LNG carriers, and cruise liners. A lot of students confuse it with the Indian Navy, but they are poles apart. The Indian Navy is a military force and is the protector of the nation’s waters, and the merchant navy is a commercial, civilian service with the primary responsibility to transport goods and people in the sea.
The shipping business accounts for a large share of world trade, from oil and cars to electronics and grain. You need well-trained people to drive, run the engines, and keep them safe. It is for that extreme demand that the career of the Merchant Navy holds in popularity year after year.
Main Departments on a Ship
A ship functions on the combined efforts of a small number of vital departments. Navigation, cargo work, ship security, and its officers are deck officers. The captain or master of the entire vessel originates from this department. The engineering department is responsible for the maintenance of the main engine, generator, and all other machinery, and its officers are the marine engineers. Electrical and electronic systems are the responsibility of the electro-technical department under the Electro-Technical Officer (ETO). And the catering and hospitality team also look after food and services onboard that are of particular significance on the cruise ships.
Why Choose Merchant Navy as a Career?
There are many reasons why students are attracted to a career as a seafarer. The wages are often higher than many shore jobs of the same level, even at junior levels. As part of your job, you get to travel to ports in different countries. The career path is well defined; you rise through the ranks and experience from cadet to captain or chief engineer. You get a good period of leave at home after each contract at sea. Indian seafarers are also respected globally, which generates consistent demand. Moreover, life at sea builds discipline, encourages teamwork and teaches you to deal with challenging situations with a cool head.
However, it is not an easy life. You will be away from your family for months at a time, working in shifts in rough weather and isolation. Generally, students who have a passion for the sea and are prepared for this lifestyle tend to thrive.
How to Join Merchant Navy After 10th
There are a lot of students wondering if they can enter the Merchant Navy after class 10 or not. The answer is yes, but for limited posts. The GP Rating course is the standard way, and there are a couple of other alternatives.
GP Rating Course (After 10th)
GP rating means General Purpose Rating. Is a 6-month pre-sea training programme approved by DG Shipping. You take it; you join ships as a rating – that is to say, a member of the crew who helps the officers with deck and engine work.
Generally you are required to have passed Class 10, with minimum marks in English and overall as prescribed by the institute and DG Shipping. Some institutes give preference to candidates who have completed class 12. The normal age range is 17.5 to 25 years, and you must be medically fit as per DG Shipping regulations. Rules and cut-offs may vary, so always confirm them from the institute and the official DG Shipping website prior to submitting the fee.
Steps to Join Merchant Navy After 10th
First, you have to check your eligibility as per marks, age and medical standards. Secondly, the most important thing is to select a DG Shipping-approved institute because a course from a non-approved institute has no value. Then you apply and go through the selection procedure of the institute, which may be a small test or interview. Lastly, you get your medical examination done by a DG Shipping-approved doctor.
After selection, you complete 6 months GP Rating training, which includes basic seamanship, firefighting, survival at sea and safety. You then get your seafarer documents, like the CDC (Continuous Discharge Certificate) and INDoS number. Lastly, you search for ship jobs from a genuine, registered RPSL recruitment agency.
Other Options After 10th
There is also a GP rating, and you may find work in catering and hospitality on board ships that require less training, and you can find them on cruise liners. So, the wisest and smartest decision for long-term staying of many students is to study further to Class 12 with PCM. To become an officer such as a deck officer or marine engineer, you require a science background, so taking PCM in 11th keeps that door open.
Here is to illustrate the simplicity. Rohan completes class 10 and cannot study science any more due to financial pressure, so he takes up a GP Rating course and signs up with a ship as a rating. His pay and rank increase gradually, but he begins earning at an early age. One of his classmates, Neha, opts for PCM, clears the IMU CET, and joins as a cadet on the officer track. Both routes are okay, but different startlines.
How to Join Merchant Navy After 12th
Now imagine that in 12th with physics, chemistry, and mathematics, a lot of doors get opened at once. Officer-level positions are available in both the deck and engine departments, and the courses have been approved by DG Shipping.
Steps to Join Merchant Navy After 12th
First off, check if you are eligible; that is, if you have passed PCM in Class 12 with the minimum marks prescribed along with English (language) at least at the 50% level. Now choose your deck (Nautical Science) or engine (Marine Engineering) branch. Then start preparing for the admission tests; the IMU CET is the door opener for most of the courses, while a few institutes have their own exams.
But then apply online for the exam and for the admission or counselling. Pass your medical test, and then get admission into a college recognized by DG Shipping or an IMU campus. Then finish your course and the obligatory sea training to get your officer certification. The objective is clear: pick a course, clear the entrance procedure, and finish training in an approved institute.
Merchant Navy Eligibility Criteria
The eligibility criteria for the Merchant Navy vary as per the course you opt for, but the basic pattern is more or less easy.
Educational Qualification
For GP Rating, you generally need to be 10th pass, though institute rules can vary. For DNS, B.Sc Nautical Science and B.Tech Marine Engineering, you need Class 12 with Physics, Chemistry, Maths and English. For IMU CET-based programs, the general requirement is at least 60 percent aggregate in Physics, Chemistry and Maths in Class 12, along with 50 percent in English in both Class 10 and Class 12. These numbers can be updated, so always check the latest official notice.
Age Limit
Age limits are different for each course and category. The B.Tech courses through IMU CET are subjected to a maximum age limit of 25 years for General Male candidates; on this age limit, relaxations are applicable for OBC, SC/ST and female candidates. Candidates are generally required to be not less than 17.5 years old and not more than 25.
Nationality
Only Indian nationals can apply for the IMU CET.
Medical Fitness Requirements
You must pass a medical exam by a DG Shipping authorized doctor to get admission to the Merchant Navy. The doctor tests your vision, with and without glasses, within limits as per whether you are going for deck or engine. Color vision is crucial, and deck officers in particular must be able to read navigation lights and signals properly. Both ears must be able to hear, and your ears must be in general health and clear from any heart, lung, spine, or nervous system ailment. Your height and weight need to be proportionate, and you will also be subjected to urine and blood tests and an X-ray.
Tip: Get a basic eye check done well in advance—preferably in Class 11 or 12. If you have a color vision deficiency, you can still pursue differentiation in engineering or a shore-based maritime profession, but it’s better to know that before you invest your time and money on a deck course.
Merchant Navy Courses After 12th
There are many merchant navy courses after 12th, and most of them are maritime courses recognized by DG Shipping. Each leads to a somewhat different career path.
DNS is a 1-year pre-sea program for the deck side. It is designed for Class 12 PCM students who wish to pursue a career as a deck officer. You are trained in navigation, ship stability, cargo handling, maritime law, and safety. Upon completion of the course, you serve your sea time as a deck cadet and then sit for the competency exams to move up the ranks. DNS is a shorter course than a degree; however, since the entire syllabus is condensed into one year, it requires a high level of self-discipline.
B.Sc Nautical Science
It is a 3-year course in nautical science, followed by training at sea. It is appropriate for students who desire to pursue both a conspectus of a university degree and a deck officer career. The extra plus here is flexibility, because a degree won’t hurt if you ever decide to go shore-based later in life.
Marine Engineering
Marine engineering is a four-year engineering degree related to ship engines, machinery, and systems. This course is suited for students who like mechanical and engineering subjects. As a marine engineer, you’ll work your way up from fourth or third engineer to chief engineer. Graduate mechanical engineers also have a 1-year path called GME (Graduate Marine Engineering), which is nice to know if anyone in your family asks about it.
Electro-Technical Officer (ETO) Course
This is also a condensed course for students passionate about electrical and electronics work on ships. With modern ships increasingly dependent on automation and electronic systems, the demand is rising.
GP Rating After 12th
Students can also apply for the GP Rating after completing Class 12, based on the Institute guidelines. It’s not the officer route, but it is a faster way to get out there and start earning at sea.
Quick Comparison
In simple words, GP Rating takes 6 months, and you will be at the rating level. DNS is 1 year and begins the decry officer track. B.Sc. Nautical Science is a 3-year duration course that also prepares you for the deck officer roles with a degree. B.Tech Marine Engineering is a 4-year course and leads to the engine officer track. “The shorter the course he starts, the faster the pace, the longer the degree, and the more you have academic credentials.
Merchant Navy Entrance Exam Preparation
For most officer-level courses, the entrance exam is your biggest hurdle. Preparation for the Merchant Navy entrance exam is an early and consistent process, so let us first discuss the primary exam.
IMU CET Exam Details
The IMU CET (Indian Maritime University Common Entrance Test) is the national entrance examination for admission to IMU campuses and many other affiliated or DG Shipping-approved maritime institutes. The exam is computer-based, conducted in English, and the time limit is 3 hours. All questions are multiple choice, and the UG and diploma level paper has 200 questions. Each wrong answer is penalized by 0.25 marks, so reckless guessing can negatively impact your score. The exam is usually conducted once a year, with registrations opening a few months in advance. For the year 2026, the IMU CET exam was scheduled to be conducted on May 24, with the last date to apply being April 24. The dates vary each year, so always refer to the official Indian Maritime University website for the most up-to-date information.
IMU CET Syllabus (Summary)
The paper is divided into Physics, Chemistry, Mathematics, English, and General Aptitude with Logical Reasoning. In physics, you will find questions on motion, force, energy, heat, optics, and elementary electricity. Chemistry is all about basic concepts, chemical reactions, and the periodic table. Mathematics is a mix of algebra, trigonometry, geometry, and basic calculus. English, on the other hand, is divided into grammar, vocabulary, and comprehension, while the aptitude section tests your ability to recognize patterns, solve puzzles, and interpret data. Most of the questions are directly based on the Class 11 and 12 syllabus and are designed to test your understanding of the fundamentals, not your ability to solve extremely complex problems.
Preparation Tips
Begin with NCERT books for classes 11 and 12, as these books cover most of the basics. Make a simple daily schedule, because two to three hours of focused studying every day for a few months are more effective than last-minute cramming. Solve previous years’ papers to get an idea about the testing pattern and difficulty level, and attempt online mock tests, as computer-based exams require you to practice on screen and test your speed.
Don’t ignore English—about 70% of students choose it as a low-scoring subject and then regret it since it has a bearing on both the eligibility and the score. Devote about twenty minutes per day to logical reasoning and be cautious with negative marking: solve the questions you’re relatively certain about first. Revise weekly from your short notes on the formulas and important points and take care of yourself, as you will have to pass a medical test anyway.
A straightforward six-month plan could turn out to be effective. Complete the syllabus, and revise NCERT in the first two months. Reserve the next two months for topic-wise problem solving and past year papers. Take full-length mock tests for last one month, analyze your errors, and revise the weak areas.
Merchant Navy Admission Process (Step by Step)
The process of Merchant Navy admission is bewildering at the initial stage, but it has a predictable pattern. You first need to see if you are eligible for the course in terms of marks, age, and medical standards. Then, apply for the entrance exam by registering an account at the official website and completing the application form. Upload the documents and pay fees as directed.
Download your admit card, note down your exam city and time, and appear for the exam. Check your score. Once the result is announced, check the score and download the rank card. Eligible candidates then register for counselling, which is conducted in multiple rounds consisting of registration, choice filling, seat allotment, and reporting. Once you get a seat, report to the allotted college for document verification, undergo the medical examination if you have not done so, and deposit the admission fee to secure your seat. Institutes sometimes also conduct spot admission if seats are left vacant after the main rounds. So keep checking the official websites.
Admission Documents Required
Retain both the original and photocopy of your Class 10 mark sheet and certificate, as it is used in proof of your date of birth, and also the Class 12 mark sheet and passing certificate. You should have your IMU CET admit card and rank card, an identity proof like an Aadhaar card, and passport-size photographs. Subsequently, you require a passport for sea service, so get one early. Other documents are the medical fitness certificate issued by a registered doctor, a caste certificate if you are from the SC, ST, or OBC category, transfer and migration certificates if applicable, and your bank details along with the fee receipt.
One tip that may help you is to maintain both a hard copy and a soft copy for all documents. The admissions periods are very brief, and a missing document is one of the leading causes of delay.
Deck Department Ranks
A deck career usually begins as a deck cadet. Then you become Third Officer, Second Officer, Chief Officer, and finally Captain, also known as Master, who is the head of the ship.
Engine Department Ranks
Engine ranks start with Engine Cadet or Trainee Marine Engineer. Then you become Fourth Engineer, Third Engineer, Second Engineer, and finally Chief Engineer, who is responsible for all the machinery on the ship.
Rating-Level Roles (After GP Rating)
You can work as an ordinary seaman or able seaman in the deck department or as a wiper, motorman, or fitter in the engine department after GP rating. As you gain experience, you can advance to more senior rating positions like Bosun.
Shore-Based Jobs Later in Life
Many seafarers transition to shore-based roles after ten to fifteen years at sea. Marine surveyor, port operations manager, ship management or fleet superintendent, maritime trainer or lecturer, marine insurance or logistics professional, and ship broker or charterer are common shore roles. This is one of the reasons the Merchant Navy is considered a career for life and not just a job at sea.
Salary and Growth Opportunities
The salary will vary with your rank, the type of ship, the shipping company, and the length of your contract, so the figures below are approximate. Cadets typically receive a modest stipend. Junior ratings may make approximately 20,000 to 50,000 rupees per month. Third officers and fourth engineers often make 1 to 2 lakh rupees per month. Second officers and third engineers may make 1.5 to 3 lakh rupees. Chief Officers and Second Engineers may make 3 to 6 lakh rupees, and Captains and Chief Engineers may make 6 lakh rupees or more per month, sometimes significantly more.
Actual pay varies by ship type, with tankers often paying higher than some other segments, and also depends on the company’s policies and market conditions. Certain seafarers may be eligible for tax advantages depending on their residency status, so it is always advisable to consult with a tax professional regarding your specific situation.
Growth is achieved by serving the required sea time and passing the competency examinations mandated by DG Shipping. With each successive step, you take on more responsibility and are compensated accordingly. Additional certifications, such as tanker endorsements or advanced safety courses, can also enhance your earning potential.
Mistakes To Be Avoided By Students
There are a lot of students who lose their time and money just because of some silly mistakes. The biggest is for non-approved providers, so always check DG shipping approval from their official website. Be wary of statements such as ‘100% placement’, as no real institute can assure a job, and demand actual placement records.
Do not pay agents for direct admission, as fraudulent agents abound – apply through official routes only. Don’t slack on medical requirements, and test your eyesight (and colour vision) as soon as you can. Do not underestimate the importance of entrance examination preparation, as, just like anyone else, a great student can lose out if he/she doesn’t prepare for it, and do not underestimate English.
Talk to actual seafarers to get a feel for the life before you commit, and don’t miss registration or counselling cutoff dates. Always make backups of your documents, and be careful about who you give your original documents to. And never trust job offers from companies without a valid RPSL licence.
