You are underway in an area of reduced visibility and hear a sound signal. It is likely coming from the starboard bow; however you cannot locate the other vessel either visually or with the radar. Which of the following actions should you take?

As the sound signal appeared to come from forward of your vessel’s beam, you should reduce speed to the minimum and navigate with extreme caution.

As the sound signal appeared to come from starboard side, you should alter your course to starboard and carefully pass astern of the other vessel.

As the sound signal appeared to come from forward of your vessel’s beam, you should alter your course to port side and observe the situation.

You should immediately clarify the situation with a radio call, since you cannot detect the other vessel.

You have visually detected a vessel displaying the lights below. What is the status of this vessel?

Not under command.

Not making way through the water.

Making way through the water.

Constrained by their draught.

Restricted in their ability to manoeuvre.

Both vessels should take action.

The vessel(s) should alter their course to port side until a safe passing distance is predicted.

The vessel(s) should reduce their speed until a safe passing distance is predicted.

You have visually detected a vessel displaying the day shapes below. What is this status of this vessel?

Vessel towing another vessel, length of the tow is over 200 m.

Vessel towing another vessel, length of the tow is less than 200 m.

You have visually detected a vessel displaying the lights below. What is the size and status of this vessel?

Vessel under 50 m in length towing, total length of the tow is under 200 m.

Vessel over 50 m in length towing, total length of the tow is under 200 m.

Vessel over 50 m in length towing, total length of the tow is over 200 m.

Vessel under 50 m in length towing, total length of the tow is over 200 m.

The International Maritime Organization implemented traffic separation schemes (TSS) to ensure safe navigation in such areas. Which of the following statements are true when navigating near a TSS?

When entering or leaving a lane, vessels should keep a small angle to the direction of traffic.

If a TSS lane is inconvenient vessels can navigate in opposite directions next to it.

Crossing TSS is not permitted, vessels should navigate around them.

Vessels are only permitted to join a TSS at the beginning or end of the lane and not in between.

When entering or leaving a lane, vessels should indicate this with a large angle to the direction of traffic.

Whenever possible, ships should join or leave the TSS at the beginning or end of the lane with particular caution.

Any vessel that is not using or crossing the scheme should keep a wide distance to it.

Please complete the following sentences: “Generally, the COLREGS apply to ____ upon the high seas and in ____. In territorial waters, ____ national regulations may apply.”

… all vessels … all connected waters … additional.

… commercial vessels … all connected waters … additional.

… all vessels … international waters only … additional.

The COLREGS require actions taken to avoid collision to be clearly visible to other vessels. What does this mean for collision avoidance manoeuvres?

One large manoeuvre should be carried out so that the affect is clearly visible to the other vessel.

Several small manoeuvres should be carried out, to ensure that the other vessel is watching during the manoeuvres.

No manoeuvres are necessary if the other vessel is detected with radar only.

Which of the following statements regarding the “stand-on” vessel is true?

If early actions have failed and the vessels are close to each other, the stand-on vessel is urged to carry out whatever manoeuvre is necessary to avoid a collision.

It may be necessary for the stand-on vessel to alter their course or speed if it becomes clear that the give-way vessel is not taking appropriate action to avoid a collision.

IF a stand-on vessel needs to act during a crossing situation, it should avoid course alterations to the port side so as not to counter any action that the give-way vessel might still take.

If a stand-on vessel needs to act during a crossing situation, it should avoid course alterations to the starboard side so as not to counter any action that the give-way vessel might still take.

Rule 17 requires stand-on vessels to maintain their course and speed under any circumstance.

Specific rules apply to vessels inside narrow channels. All vessels travelling along a narrow channel should:

Stay as much to their starboard side as safely possible.

Sound one prolonged blast to alert others of their presence.

Also sound one prolonged blast as an answer.

Avoid anchoring.

Besides actions to avoid collisions, the COLREGS may also require vessels to take action so as not to impede the safe passage of other ships, for example, when the other vessel is restricted by their draught. In these circumstances, which of the following statements are true?

Actions to not impede the safe passage of other ships do not relieve the other vessel from their obligation to take action to avoid a collision.

Actions to not impede the safe passage of other ships should be taken early to allow sufficient sea-room for the other ship.

Actions to not impede the safe passage of other ships mean that the other vessel does not need to take action to avoid a collision.

Actions to not impede the safe passage of other ships are only required for non-commercial ships, such as sailing boats.
