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?
Under the Rules a proper lookout should be maintained at all times and by all available means.
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.
The ship has a right-handed propeller and is swinging to starboard when the engines are slow ahead and the rudder is to starboard. The engines are stopped and the rate of swing rapidly slows down. How could the swing to starboard be maintained without the ship making much headway.
By applying the rudder hard over to starboard and going ahead on the engines.
Astern on the engines will allow Transverse Thrust to continue the swing.
The only effective method is by using the bow thruster to push the bow to starboard.
Transverse Thrust will reduce the swing and therefore a kick ahead is necessary with full starboard helm applied.

Risk of collision is deemed not to exist and I will maintain my course and speed. I will continue to monitor the situation.
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. However, to be sure of a safe passing distance, I will reduce my speed to allow the other vessel to pass ahead.

The rudder should be put Hard to Port to reduce the water flow to the left side of the propeller.
The rudder can be put to Hard to Port to reduce the water from to the right side of the propeller.
