Why should a Ground Stabilised True Motion radar display not be used for anti-collision purposes?
Because this display is only ever used for navigation.
The true vector can never give an indication of collision risk with another ship.
The “aspect” of the target is confused, so the Regulations for Preventing Collisions cannot be accurately applied.
True motion does not provide the collision risk of targets as only true vectors are available.
The maximum rudder angle on your ship is 35°. Do you think this is the angle that the rudder is most effective?
No, the rudder is most effective at small rudder angles.
No, the most effective rudder angle is about 25 to 30°, this is because the rudder is stalling at 35° angle.

The stern will “back” into the wind and the ship’s heading will swing to starboard.
The stern will fall off to starboard, making the heading swing to port.
The bow will “seek” the wind and the ship will swing to port.
The ship will go straight astern and the heading will remain approximately the same.

Varies, but can be determined from trial data.
15 ship lengths.
4 nautical miles.
Two ships travelling in opposite directions are to pass each other in a narrow river, as illustrated. Explain what is likely to happen as they pass each other?
Due to interaction, the bows will repel each other, and then when alongside each other the two ships will be sucked together and finally the sterns will be repelled as they start to pass clear.
There will be very little effect between the two ships as they pass.
Due to interaction, the bows will attract each other as they approach, then they will repel each other alongside and as they pass clear, the sterns will be attracted.
As they approach, rudder should be applied quickly to avoid sheering into the path of each other. Then as they are alongside they will be attracted and finally repel each other as they pass clear.
When navigating using the GPS, how does the GPS display indicate when the accuracy of the displayed position is reduced?
A large HDOP value is displayed on the screen.
A large “Correction Factor” number is displayed on the screen.
The GPS display flashes and sounds an alarm.
The GPS display is always very accurate and does not give any indication of lack of accuracy.
The following vessels are all required to make the same sound signal when in or near an area of restricted visibility: a vessel not under command; a vessel restricted in her ability to manoeuvre; a vessel constrained by her draught/a sailing vessel; a vessel engaged in fishing; a vessel engaged in towing or pushing another vessel.
