Vessel’s Characteristics

Turning circle and terms


The distance traveled in the direction of the original heading measured from the point at which a helm was first applied. The maximum advance is usually between 3 to 5 ship lengths for a merchant ship of any size going at full ahead and using full helm.


The distance of the center of gravity of the ship from the original track line measured in the 90º to the original heading. The transfer for a turn of 90º is about two ship lengths

Tactical Diameter

It is the transfer for a turn of 180º which is almost equal to the maximum transfer. It is usually about the same distance as the maximum advance.

Drift Angle

It is the angle between the tangent to the turning circle at any point and the fore and aft line of the ship.

Pivot Point

It is the point about which the vessel pivots with the bow swinging inwards and the stern swinging outwards. It is about one third (1/3) of the vessels length from forward when going ahead. When going astern the vessel pivots about approximately one quarter of the length from astern.

Final Diameter

It is the diameter of a circle traversed by a vessel after turning through 360º and maintaining the same speed and rudder angle. This diameter is always less than the tactical diameter. It is measured perpendicular to the original course and between the tangents at the points where 180º and 360º of the turn have been completed.

Merchant Navy Jobs in India

We know that 90% of total cargo is transported through ships but even after that people are not getting Jobs and struggling hard. Collages are unable to bring companies to campus so what now? One of the common way to get job in India is going to Mumbai with your CV and try visiting different companies. Another way is going to an agent (We are against it and fraud is common ).

Blog, 4th Dec 2019, MUMBAI

I am thinking of writing my day to day experience so that people know how it feels in merchant navy line. Yes making videos will be more convenient for you guys to watch but that is a bit time consuming but i will definitely start making videos.

It is very fascinating as it offers 6 month of job and 6 month of rest or free time. But the actual story is quiet different initially as a deck cadet i will get a contract of 9 Months (+- 1 month). And this is really a long time almost a year. So it is going to be difficult as i never stayed away from home for this long. Have stayed Maximum of 6 months and that felt long at the end.

There are so many Questions poping in my mind right now.

  1. Is Merchant Navy a Right choice ?
  2. Is it a good choice for long term like 10-12 years?
  3. How it feels on board?
  4. Work culture?
  5. Away from family & friends for 9 months?

Answering all these questions require Experience, So what i will basically do is wait & experience things.And put everything on this blog column of the website and even try putting videos for everyone.
