What situation is this vessel in based on the lights displayed?
- A.
  
  Vessel constrained by draft
- B.
  
  Vessel not under command
- C.
  
  Vessel at anchor
- D.
  
  Vessel aground
Correct Answer
D. Vessel aground

Explanation
Based on the lights displayed, the vessel is in a situation where it is aground. "Aground" refers to a vessel that is stranded or stuck on the bottom of the sea or waterway. The lights displayed by a vessel aground may vary, but typically they would include a white light at the forward end and a red light at the aft end. This indicates that the vessel is unable to move and is stuck in a fixed position.

Review the picture below and determine the signals that should be displayed.
- A.
  
  Two red lights with 225 degree forward arch
- B.
  
  Anchor ball or light is adequate
- C.
  
  Two red all-round lights, one anchor light and deck lighting

  Red - White - Red all-round lights with anchor ball or light
Correct Answer
C. Two red all-round lights, one anchor light and deck lighting

Explanation
The correct answer is "Two red all-round lights, one anchor light and deck lighting". This is because according to the picture, there are two red all-round lights, which are required for a vessel that is not under command or restricted in its ability to maneuver. Additionally, there is one anchor light, which is necessary when the vessel is at anchor. Finally, there is deck lighting, which helps to illuminate the deck of the vessel for safety purposes.

The correct EPIRB for use in Australian waters is now:
- A.
  
  406 Mhz
- B.
  
  121.5 Mhz
- C.
  
  243 Mhz
- D.
  
  800 Mhz
Correct Answer
A. 406 Mhz

Explanation
The correct EPIRB for use in Australian waters is 406 Mhz. This frequency is recommended because it allows for more accurate and reliable distress signal transmission and can be detected by satellites. The 121.5 Mhz frequency was previously used but is now being phased out due to its limitations in terms of signal accuracy and satellite detection. The 243 Mhz and 800 Mhz frequencies are not commonly used for EPIRBs in Australian waters.

Which of the following boats handle adverse conditions on a bar the best?
- A.
  
  Punt
- B.
  
  Shallow V
- C.
  
  Displacement
- D.
  
  Deep V hull
Correct Answer
D. Deep V hull

Explanation
A deep V hull is the best type of boat for handling adverse conditions on a bar. This type of hull has a sharp V shape at the bottom, which allows it to cut through rough waves and choppy waters more easily. The deep V hull provides better stability and control, reducing the chances of capsizing or losing control in adverse conditions. It also helps to minimize the impact of waves and provides a smoother ride, making it the ideal choice for navigating through challenging waters.

The formula for carrying fuel is:
- A.
  
  One third out, one third back and one third in reserve
- B.
  
  Two thirds out and one third back
- C.
  
  One half out and one half back
- D.
  
  Just make sure the tank is full
Correct Answer
A. One third out, one third back and one third in reserve

Explanation
The correct answer is "One third out, one third back and one third in reserve." This formula suggests that when carrying fuel, one should use one third of the fuel for the outbound journey, another third for the return journey, and keep one third as a reserve. This approach ensures that there is enough fuel for the entire trip and also accounts for any unexpected circumstances or emergencies that may require additional fuel.

It is illegal in Australia for any person with a blood alcohol level of ___ or above to operate a powerboat.
- A.
  
  .05
- B.
  
  .08
- C.
  
  1.0
- D.
  
  2.0
Correct Answer
A. .05

Explanation
In Australia, it is illegal for any person to operate a powerboat if their blood alcohol level is .05 or above. This is because alcohol impairs a person's judgment, coordination, and reaction time, which can increase the risk of accidents and endanger the safety of both the boat operator and others on the water. The legal limit of .05 is set to ensure that boat operators are sober and capable of safely navigating the waterways.

  Keep well clear of the way of the vessel you are overtaking
Correct Answer
D. Keep well clear of the way of the vessel you are overtaking

Explanation
When overtaking another vessel, it is important to keep well clear of its way. This means maintaining a safe distance and ensuring that there is enough space between the two vessels to avoid any collision or interference with each other's course. By keeping well clear, you minimize the risk of accidents and ensure a safe and smooth overtaking maneuver.

- A.
  
  Smooth boating
- B.
  
  A rough ride
- C.
  
  To anchor before high tide
- D.
  
  Good fishing weather
Correct Answer
B. A rough ride

Explanation
When the wind is blowing against the tide, it creates opposing forces that can result in rough conditions on the water. The wind pushes against the tide, causing waves to become larger and choppier. This can make boating more challenging and uncomfortable, leading to a rough ride.
