True motion does not provide the collision risk of targets as only true vectors are available.
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.

You are on a sailing vessel, underway in open water. This vessel is sighted on the starboard bow, on a steady bearing and the distance is closing. By the International Regulations for the Preventing Collisions at Sea, what action will you follow?
This vessel is clearly a power-driven vessel and I anticipate that the bearing will therefore close and she will pass ahead at a safe distance.
Risk of collision is deemed to exist and, as the other vessel is on a steady bearing on my starboard side, I am required to keep out of the way. I will make a broad alteration of course to starboard.
By Rule 18, a power-driven vessel underway shall keep out of the way of a sailing vessel. I will maintain my course and speed, but will continue to monitor situation to ensure the other vessel takes avoiding action.

8 nautical miles.
4 nautical miles.
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.

Both ships have normal anchor watch responsibility in addition to watching ship to ship fendering, mooring etc.

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.
