Q. 1) What is transit bearing ? what is its use ?
X
when we observe 2 or more terrestrial prominent objects in a line it is called a transit bearing.the transit bearing of these prominent objects are sometime joined by a line and true bearing is mentioned on chart otherwise we can use the parallel ruler to see their transit bearing value and compare with compass bearing taken from vessel to obtain compass error
Q. 2) All fire fighting resources available in galley.
Xi answered either dcp or co2 portable extinguisher;fire blanket;fixed fire fighting system for deep fat fryers.
Q. 3) He has cards for signal flags and he asks them always and also day signal cards
XQ. 4) What is a hatchet in lifeboat and its use ?
XHatchet is basically a term used for hammer, it is used to cut/break/free any object which may be entangled to the life boat.
For eg. Cutting of painter wire.
If very small object is stuck/entangled to the boat, you may cut it with "jack knife" which is commonly known as Swiss knife (object which has knife,scissor, fork, spoon, etc.)
Q. 5) What is crash stop ?
XInertia Stop
As described above, when the engine of the ship is stopped, the ship will continue moving in the same direction for some more distance due to inertia. Here no astern command is given (used to produce braking effect for ships), and hence ship will travel more distance in the inertia stop method.
Crash Stop
Crash stop is usually the term used when the ship has to sudden stop in emergency situation. Here the engine, which is moving in an ahead direction is given an order for full astern, leaving the rudder in the mid ship position to stop the ship within minimum distance and shortest possible time. To know the complete procedure read for crash stopping read crash manoeuvring.
In general operation i.e. berthing or departure of the ship from port or manoeuvring through channel or narrow passage, the above two methods are combined for a swift navigation of the ship i.e. in between giving an astern kick to stop and slowing down the ship's speed for better manoeuvring.
The stopping distance data and chart is given in sea trials of the ship and made handy on bridge for reference. Every deck officer must refer this data to master the navigation of the ship.
The data may differ when used due to variation in weather condition, ships loading, stability and other factors; however, deck officers can compare the trail data and make use of it in practical situations.

Q. 8) What all fixed fire fighting systems have you seen onboard your ships in engine room ?
XQ. 9) What is stranding ?
XDifference between stranding and beaching?
Stranding means when a vessel has run aground, it is accidental. In consequence, the double bottom area of the vessel will probably suffer considerable damage, especially if the ground is rocky. This is physically the same action as beaching, but with the significant difference that beaching the vessel is an intentional action and under comparatively controlled conditions, whereas stranding is accidental. Circumstances will vary with different ships,but selecting a convenient position to ‘set down’ will in all probability never arise. In consequence, the double bottom area of the vessel will probably suffer considerable damage, especially if the ground is rocky.
The method of procedure to follow on stranding can only be an outline, when one considers how circumstances may vary. Here are some guideline to follow:
Prepare records in time series on the matter at the time and after the accident.
If another ship is responsible for the accident (e.g. illegal navigation), confirm the name of the ship, ship owner, operator, Master, port of registry, last port, and next port, and tender a claim notice
