People starting a maritime career often mix up the Merchant Navy, the Indian Navy, and the Coast Guard. They all work at sea, but their missions, rules, pay, entry requirements, and day-to-day life are very different. This guide lays out the Merchant Navy vs Indian Navy vs Coast Guard in plain language — useful if you’re a student exploring options or a seafarer weighing a move.
Three different seas, three different jobs
The Merchant Navy is commercial shipping: cargo, passengers, and trade. The Indian Navy is the country’s naval defence force, warships, submarines, and combat-ready personnel. The Coast Guard is a first line of defence, a law-enforcement and safety force focused on coastal protection, search-and-rescue, and anti-smuggling.
If you’re deciding between careers, thinking about Merchant Navy vs Indian Navy or Navy vs Coast Guard, start by matching your goals: commercial income and global trade (Merchant Navy), defence and combat (Indian Navy), or coastal law enforcement and rescue (Coast Guard).
Fundamental difference: purpose and control
- Merchant Navy: Commercial by nature. Ships transport goods and passengers under international shipping rules (IMO). Operators can be private companies or state-owned lines. The job is industry-driven, not military.
- Indian Navy: Defence force regulated and run by the government. The Indian Navy protects the nation’s maritime borders, engages in international naval exercises, and is focused on national security.
- Coast Guard: A specialized maritime service that concentrates on the country’s coastline. The Coast Guard enforces maritime law, performs search and rescue, and prevents illegal activities such as smuggling.
When you weigh Merchant Navy vs Indian Navy, you’re really choosing between commerce and defence and coastal protection/law-enforcement roles.
Eligibility and entry: what you need to join
Merchant Navy
- Typical entry requires 10/12 with Physics, Chemistry & Maths (60% for many courses).
- For officer roles: bachelor’s in marine engineering or nautical science.
- Age brackets commonly 17–25 for cadet entries.

Pay and allowances: commercial vs government pay
Merchant Navy
- Pay varies widely by rank, ship type, and trade route. Even junior crew can earn $200–$300 monthly as a starting point, while officers may earn thousands USD per month. Merchant seafaring is known for relatively high pay in senior ranks.

When choosing between Merchant Navy vs Indian Navy, remember that commercial shipping follows trade cycles, while defence recruitment follows government policy and exam cycles.
Retirement, service period & pension
Merchant Navy

Indian Navy

Medical and fitness standards
Merchant Navy
- Medical checks by DG Shipping-approved doctors; stringent eyesight and health norms (6/6, no color blindness). Height and weight minimums often apply.
Indian Navy
- Physical fitness tests and medical exams with specific minimum height and other standards; tattoos and physical fitness rules can be restrictive.
Coast Guard
- Fitness and medical standards align closely with naval requirements but with their own nuances.
Operational roles and scope
- Merchant Navy: Transport goods, commercial logistics, global trade routes. Work is industry-focused—loading, navigation, engine maintenance, passenger services.
- Indian Navy: Combat-ready fleet, warship operations, strategic defense, international cooperation, and rescue operations.
- Coast Guard: Coastal security, anti-smuggling, fisheries protection, pollution control, search-and-rescue operations, and law enforcement.
This makes the Merchant Navy vs Indian Navy vs Coast Guard choice fundamentally about mission: commerce vs defence and coastal specialization.
