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.

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.
Risk of collision is deemed to exist and, as the other vessel is on a steady bearing on my starboard side, I will maintain my course and speed.
When the temperature of the air increases with height it is known as a “Temperature Inversion” and may influence the performance of some instruments on the ship. What should the bridge Officer of the Watch be prepared to happen?
The GPS may give errors of position because of interference of incoming signals from the satellites.
The radar will be show abnormal sea clutter as the pulse is trapped by the inversion.
Abnormal ranges of VHF RT and Second Trace Returns on the radar.
The bearings obtained from the Directional Finder (DF) will not be as accurate as normal.
The Master arrives on the bridge obviously under the influence of alcohol and states he is taking over the “con” of the ship. What actions should the Officer of the Watch (OOW) take in this situation?
Tell the Master you do not think this is a good idea and retain control of the watch.
Attempt to diplomatically avoid taking any actions that would put the ship or crew into danger and call the Chief Officer for assistance.
Tell the Master you consider him incapable of taking over the responsibility of the watch and that he should retire to his cabin and sleep it off.
Watch the actions made by the Master and if not dangerous, wait until the Master becomes more capable to take control or leaves the bridge.
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?
Yes, the rudder can be put to port.
No, the rudder should be kept amidships when going astern and there is little that can be done to reduce the swing to starboard.
The rudder can be cycled from side to side.
The rudder should be put hard to starboard to reduce the water flow to the left side of the propeller.
You are approaching the port entrance. What do these lights mean?
