This vessel is encountered at the mouth of a river. According to the International Regulations for Preventing Collisions and the illustrated shapes, what type of vessel is it?
This is a vessel engaged in dredging or underwater operations. The two balls in a vertical line indicate the side on which it is safe to pass; the two diamonds in a vertical line indicate the side on which an obstruction exists; the ball/diamond/ball indicate that the vessel is restricted in her ability to manoeuvre.

You are on a power-driven vessel underway in open water. You sight these lights on the port bow, on a steady bearing. The distance is closing. What are you looking at and what action will you take in compliance with the International Regulations for Preventing Collision at Sea?
This is a power-driven vessel, more than 50 metres in length or less than 50 metres in length and showing a second masthead light, restricted in her ability to manoeuvre. The sidelight of a second vessel can be seen beyond her. Under rule 18, I am obliged to keep clear of the first vessel and will therefore take appropriate avoiding action.
This is a power-driven vessel engaged in towing, less than 50 metres in length, length of tow under 200 metres and the tow, both being restricted in their ability to manoeuvre, seen from the starboard side. Under rule 18, I am required to keep clear and will take appropriate avoiding action.
Once a ship (equipped with self-stowing auto-tension winches) is moored alongside a loading or discharging berth, how is it recommended that the winches are set?
All mooring winches be left in “auto-tension” mode.
All winches to be left with the manual brake on and out of gear.
The “breastline” and “headline” winches be left in the auto-tension mode and spring winches with manual brake on.
The “spring” winches be left in the auto-tension mode and all other winches with the manual brake on.
In an extreme case, in addition to having your winch brakes as tight as can be, you can increase the brake holding capacity of the winch drum by putting it in gear and setting the power to the “heave” position. However this may cause:
All the listed alternatives.
The increased braking power of the winch to exceed the breaking strength of the wire and rope paid out from it which might cause the wire or rope to part.
Strain on the fairleads and rollers in use in excess of their Safe Working Load.
Damage to the winch by distorting the shaft.

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.
Transverse Thrust will reduce the swing and therefore a kick ahead is necessary with full starboard helm applied.
The only effective method is by using the bow thruster to push the bow to starboard.
Astern on the engines will allow Transverse Thrust to continue the swing.
By applying the rudder hard over to starboard and going ahead on the engines.

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 should be put hard to starboard to reduce the water flow to the left side of the propeller.
Yes, the rudder can be put to port.
The rudder can be cycled from side to side.

Why should Ground Stabilised True Motion display mode be avoided when using the ARPA for anti-collision purposes?
The Relative Motion display and relative vectors is the only display to use for anti-collision purposes.
True motion does not provide the collision risk of other ships.
The true vector can never give an indication of collision risk with another ship.
The collision regulations are based on ship courses through the water.
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 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?
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 do not think this is a good idea and retain control of the watch.
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.

It would be very difficult to maintain full deep sea RPM on the engines and therefore difficult to assess the speed.
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.

Keep as far as possible on the starboard side of the channel and maintain speed to retain effective steerage.
Increase speed slightly to pass each other as quickly as possible and thereby reduce the effects of “ship to ship” interaction.
Slow down if possible without losing steerage and be prepared for prompt application of rudder to counteract any swing as they approach and pass each other.
A tug is moving towards the bow of the ship to make fast and is in the vicinity of the ship’s shoulder, as illustrated. What specific danger should be considered when making this approach to the bow?
The positive pressure field at the ships bow may repel the tug and make the connection very difficult to establish.
The tug may be turned across the bow of the ship and also suffer a lose of stability with a danger of being turned over if touched by the ship.
The stern of the tug may be sucked in towards the bow and also suffer a reduction in the positive GM, making it very unstable.

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.
