Naval Officer

Hi Shivam,
Knowing about various subjects one has to learn in each of these streams helps to get rid of most of the doubts involved with deciding between the two departments.
Engineer Officers - are the ones who handles machinery (Engine). You need to have interest in technical, be physically strong. The working environment is little bit harsh as the temperature can range from 35 to 50 Celsius. Start loving sweat and oil from today (sarcastically), but that is part of job.
Ranks in this dept are as follows
1. Chief Engineer
2. 2nd Eng
3. 3rd Eng
4. 4th Eng
5. Jr. Eng
Deck Department: Those who are not type of techie stuff then this is the best option. A person interested in management type of job will like deck dept. The work of deck officers is to navigate the ship. It's preferable to have good communication skills and leadership qualities.
Ranks are as follows:
Captain
Chief Officer
Second Officer
Third Officer
Trainee Navigating Officer
If we compare deck and engine department after they exit Merchant navy, then I guess marine engineers have better opportunities.
All the best.

The minimum age to work on a cruise ship is usually either 18 or 21 years old, depending on the cruise line, cruise ship and position you are applying for. Beach resorts usually have a minimum age of 18 years old for many of their positions.The very basic qualification is a diploma from a catering college and 1-2 years experience in the hotel industry (preferably in a 5-star hotel). For kitchen positions, you need to have experience in a continental kitchen (hot or cold). Most cruise line jobs, especially in the hotel department, are for those below 30 years of age. You also need to be fluent in English and able to communicate effectively. Other basic requirements are that you need to be healthy and fit to manage the long hours on your feet.

Additionally, it is highly monetarily rewarding in terms of monetary compensation plus quite satisfying and challenging.
