Right on the bow.
- B.
Right on the stern.
- C.
Fine on the bow.
- D.
On the beam.
Correct Answer
C. Fine on the bow.Explanation
In rough weather, it is important to point the boat into the waves to ensure stability and prevent capsizing. "Fine on the bow" means pointing the boat slightly off-center towards the bow, which allows the waves to hit the boat at an angle. This position helps to reduce the impact of the waves and provides better control and maneuverability.Rate this question:

In rough weather you loose steering, what could you do?
- A.
Lower the anchor.
- B.
Extend warps from the front of the boat.
- C.
Operate the engine astern.
- D.
Send up distress flares.
Correct Answer
A. Lower the anchor.Explanation
In rough weather, when you lose steering, lowering the anchor can help stabilize the boat and prevent it from drifting or being carried away by strong winds or currents. By anchoring, you can keep the boat in a fixed position and reduce the risk of collisions or running aground. This action provides temporary stability and allows you to assess the situation, make necessary repairs, or wait for improved conditions before continuing your journey.Rate this question:

Why do we not go at full speed in a power boat in rough seas?
- A.
Because the bow would loose buoyancy.
- B.
Cause the engine to race.
- C.
Reduces visibility.
- D.
Uses too much fuel which may be required for emergency.
Correct Answer
B. Cause the engine to race.Explanation
Going at full speed in a power boat in rough seas can cause the engine to race. This is because the rough seas create unpredictable and unstable conditions, with waves and swells causing the boat to bounce and pitch. Going at full speed in these conditions can put excessive strain on the engine, causing it to race or rev too high. This can lead to engine damage or failure, as well as potentially compromising the control and stability of the boat. Therefore, it is advisable to reduce speed in rough seas to maintain control and ensure the safety of the passengers and the boat.Rate this question:

Put on fenders.
- B.
Check for underwater obstructions.
- C.
Reduce speed for small sampans.
- D.
Refer to the smallest scale chart.
Correct Answer
C. Reduce speed for small sampans.Explanation
When in Victoria Harbour in a fast speed boat, it is important to reduce speed for small sampans. Small sampans are traditional Chinese boats commonly found in the area. They are slower and less maneuverable compared to fast speed boats, so reducing speed when encountering them is necessary to ensure the safety of both the sampans and the speed boat. This precaution helps to prevent collisions and potential damage to the sampans.Rate this question:
