Q. 1) During day tym hw will you know that a noc vessel is making way or not ?
X
Q. 2) Nuc vessel day signal card
XQ. 3) What is yaw control ?
Xit is basically a weather control...whch is adjusted by keepin higher value in heavy weather n strong winds and smaller value in calm ses...
- X
0 this control is used in auto pilot.when rough seas are encountered,vessel has a tendency to yaw about the set course.to prevent the auto pilot from correcting this,yaw control is used.
Q. 4) What is amplitude and what is its use ?
XQ. 5) Region a stbd hand lateral mark 3 points on your port bow.action ?
XQ. 6) What is transit bearing ? what is its use ?
Xwhen 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. 7) Course recorder ?
X
Instrument used to record the courses steered in the voyage from point to point .it looks likes a horizontal cylindrical drum having a recording paper with different quadrant.
Q. 8) He has cards for signal flags and he asks them always and also day signal cards
XQ. 9) 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. 10) Which instrument is used to measure sea water temperature ?
XI answered marine bucket,then he asked further if i know how does it look.i said no,so he said so you just read it in subramaniam's book.i said yes n then he moved on
