The Master, as a shipboard manager, is in overall command of the vessel and personnel on board. Being the highest ranking person, his duties and responsibilities cover the whole ship.
Technically speaking, he is the “owner’s representative”. He is responsible to the relevant Company Managers for all matters pertaining to the safe and efficient operation of the vessel.
Also called the Ship Captain or Ship Master, his decision must always lead to the safety of the ship, her crew, and the environment. That’s the basic. The company expects him to exercise good judgment that prioritizes safety, without regard for commercial considerations.
A Captain has the overriding authority, as well as the responsibility, to take any actions with respect to shipboard safety and pollution prevention. His decisions can be independent of shore intervention if necessary.
Why? Because he knows his ship and the situation better than someone ashore sitting behind a desk.
However, he may request and expect any and all necessary assistance, deemed appropriate, from the company.
Duties Overview
Imagine yourself as the Captain of a merchant vessel. What do you expect your job to be?
Would you be someone having the most freedom while enjoying a huge salary on board?
This may be partly true. But having the biggest pay, around USD12,000.00, also equates to having the biggest obligations.
As a Master, you are responsible for implementing the company’s Safety Management System (SMS). You must ensure the strict compliance of company policies, procedures and instructions. And there are also other parties like the charterers, inspectors, coast guards, and other authorities you have to deal with.
On the security side of the vessel, you also act as the Ship Security Officer, as per requirement of ISPS Code.

Responsibilities of a Merchant Vessel Captain
Responsibilities with the DPA
Since safety is always at the top of the ship’s priorities, it is important to be fully conversant with the company’s Safety Management System (SMS).
To accomplish that, you must interact with the Designated Person Ashore (DPA) through various means. The most common form is through email and telephone. Sometimes, chat or other forms of electronic communication is also an option if the preferred ones malfunction .
As the ship captain, you must follow his guidance and advice on matters related to safety, security, and environmental protection.
Incident Reporting and Follow ups
Since accidents and near miss incidents happen on ships, part of your job is to analyze and report them. This include non-conformities and/ or hazardous occurrences. In relation to that, you must also know which persons or parties to contact in case of emergency.
With advice and approval from company superintendents, you should recommend and apply corrective actions to prevent its recurrence.

Do you still want to become a Master Mariner?
The duties and responsibilities of a Master are overwhelming. Aside from that, the process of becoming a captain is also difficult.
However, they have the authority to delegate any of the foregoing responsibilities on a day to-day basis.
Thus, his duties are assigned to the Officers whom he considers suitably qualified and experienced. He still retains overall responsibility of the ship at all times.
His main job is actually to “oversee” that everything listed above is followed correctly. That is why he is at the management position on board.
All Masters of merchant vessels share the responsibility of ensuring the safety and well-being of their crew. Although the job orders may be generic, the specific documents and tasks required may vary depending on the type of ship.

Salary and Risks
Ship Master’s salary ranges from $8,500.00 to $16,000.00 depending on the company, CBA and ship type. It’s actually quite high, and even one of the highest among many profession.
But aside from the responsibilities, there are also risks involved.
If something happens to the vessel, the captain is initially held liable unless proven otherwise.
Remember also that when you sail across high risk areas without armed guards on board and pirates successfully hijack your vessel, they will immediately look for you!
Is the salary still worth the risk?
That’s another topic someday.
