Never should the Officer of the Watch be the only lookout.
During daylight when visibility and traffic allows.
A ship is equipped with a right-handed fixed pitch propeller, which when going from Full Ahead to Full Astern will make the ship sheer to starboard. Can anything be done to reduce this change in heading?

Risk of collision is deemed to exist and I will make a broad alteration of course to starboard, sounding one short blast. I will re-assess the situation when the alteration is carried out.
Risk of collision is deemed not to exist. However, to be sure of a safe passing distance, I will reduce my speed to allow the other vessel to pass ahead.
Risk of collision is a possibility. I will maintain my course and speed for now, but be prepared for an alteration of course to port if the CPA seems to be less than 0,2 nm as we draw closer.
Risk of collision is deemed not to exist and I will maintain my course and speed. I will continue to monitor the situation.
Can anything be done on a vessel with forward speed, to reduce the change in heading caused by a right hand fixed pitch propeller being put astern?

The rudder is in the hard over position with the propeller stopped and the ship turning slowly. On a ship with a single fixed pitch right handed propeller and no thrusters, what can be done to make the ship increase the speed of turn without significantly increasing the forward speed of the ship?
Give dead slow ahead on the engines and leave the rudder in the hard over position.
Give the engines a short kick ahead.
Give half astern on the engines as this will increase the rate of turn.
Give full astern on the engines until ship has stopped and then full ahead on the engines with rudder hard over.
When a ship is lying at anchor in a tidal area using both forward anchors, to what particular aspect should the officer of the watch be paying special attention?
When the ship swings to the tide the direction of swing should be controlled to avoid the anchor cables becoming wrapped round each other.
The tension on both cables should be similar, to avoid one dragging and all the weight of the ship remaining on the other anchor only.
The ship will become controlled by the tide and the wind will not be allowed to have any effect on the direction the ship lies at anchor.
The two anchors will restrict the ships swing with the tide and the ship may not lie to the prevailing current and wind.

Stop engines and call the Master.
Sound the General Alarm and plot the ships position.
What would be considered the most favourable heading of a ship when launching a lifeboat?
The ship should steer about 100° of the prevailing weather and sea with the boat to be launched on the leeside.
The ship should steer with the prevailing weather and sea on the beam and the boat to be launch on the leeside.
The ship should steer about 30° off the prevailing weather and sea with the boat to be launch on the leeside.
The ship should lie stopped in the water with the weather on the opposite side to the boat to be launched.
The bridge Officer of the Watch (OOW) is plotting the ship’s position in the chartroom, when the ship is in collision with a fishing vessel. Why would the OOW be held responsible for the collision?
If the OOW is busy with the safe navigation of the ship he should have exhibited the “Not under Command” signals and made other ships keep clear.
If risk of Collision existed, the fishing boat should have contacted the larger ship over the VHF before the collision took place.
Under the Rules the fishing vessel should have kept clear of larger vessels and the OOW would not be responsible.
Under the Rules a proper lookout should be maintained at all times and by all available means.

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 attract each other as they approach, then they will repel each other alongside and as they pass clear, the sterns will be attracted.
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.
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.
What is the correct understanding of the term “a ship with good Directional Stability”?
A ship which when the rudder is left amidships, it will continue on approximately a straight course.
A ship which when a rudder angle is applied and the ship starts to swing, will continue to swing even after the rudder is returned to amidships.
