"PAN PAN" is a radio distress call used to indicate an urgent situation that is not immediately life-threatening. It is used when there is a potential danger or concern, such as a mechanical failure, but there is no immediate risk to life. In this case, the motor failure on the boat has put the person in a difficult situation, but they are not in immediate danger. Calling "PAN PAN" would alert the local marine rescue association to the situation and prompt them to provide assistance.

### If the wind is blowing against the tide, you could expect:

• A.

Smooth boating

• B.

A rough ride

• C.

To anchor before high tide

• D.

Good fishing weather

B. A rough ride
Explanation
When the wind is blowing against the tide, it creates opposing forces that can make the water surface choppy and turbulent. This can result in a rough ride for boats as they navigate through the waves created by the wind and tide. The combination of wind and tide working against each other can make the water conditions unpredictable and challenging, leading to a rough and uncomfortable experience for boaters.

### Which of the following checks (3) are necessary to ensure your propeller is useable?

• A.

It is securely mounted to the shaft.

• B.

The paint is not worn.

• C.

There is no surface rust.

• D.

There are no cracks.

• E.

There are no dents in the leading edge.

• F.

There is no oil inside your propeller.

A. It is securely mounted to the shaft.
D. There are no cracks.
E. There are no dents in the leading edge.
Explanation
To ensure that a propeller is usable, it is necessary to check if it is securely mounted to the shaft, as a loose propeller can pose a safety risk. Additionally, it is important to check for cracks in the propeller, as they can indicate structural damage that may affect its performance. Lastly, checking for dents in the leading edge is important because dents can disrupt the airflow and decrease the propeller's efficiency.

### Which one of these anchors would a small boat use on a rocky sea bed?

• A.

Anchor A

• B.

Anchor B

• C.

Anchor C

B. Anchor B
Explanation
Anchor B is the correct answer because it is specifically designed for rocky sea beds. It is usually heavier and has sharp flukes that can dig into the uneven surface of the rocky sea bed, providing better holding power and stability for a small boat. Anchor A and Anchor C may not be suitable for rocky sea beds as they may not have the necessary features to hold securely in such conditions.

### If you were boating in calm weather and decided to anchor in 3 metres of water, approximately how much anchor rope should you let out (in addition to the 2 metres of chain)?

• A.

13 metres

• B.

24 metres

• C.

6 metres

• D.

30 metres

A. 13 metres
Explanation
To anchor a boat in calm weather, it is recommended to let out a total of 5 times the depth of the water. Since the water is 3 meters deep, you would need to let out 15 meters of anchor rope. However, since there is already 2 meters of chain out, you only need to let out an additional 13 meters of anchor rope.

### If you have a 2-stroke engine that runs a mixture of 50:1, how much oil would you have to add to 25 litres of fuel.

• A.

250ml

• B.

500ml

• C.

750 ml

• D.

1 Litre

B. 500ml
Explanation
In a 2-stroke engine running a mixture of 50:1, it means that for every 50 parts of fuel, 1 part of oil is required. To calculate the amount of oil needed for 25 liters of fuel, we divide 25 by 50 to get 0.5 liters, which is equivalent to 500ml. Therefore, you would have to add 500ml of oil to 25 liters of fuel.

### Sacrificial anodes should be replaced when they are smaller than 60% of their original size.

• A.

True

• B.

False

A. True
Explanation
Sacrificial anodes are used to protect metal structures from corrosion by sacrificing themselves. Over time, these anodes gradually erode as they protect the metal. When the anodes are smaller than 60% of their original size, it indicates that a significant amount of material has been sacrificed and they may no longer be effective in preventing corrosion. Therefore, it is necessary to replace them at this point to ensure continued protection for the metal structure.

### Which of the following statements about fuel is true?

• A.

All fuel should be thrown out after 3 months

• B.

2-stroke mixtures should be thrown out after 3 months and 4-stroke after 6 months

• C.

2-stroke mixtures should be thrown out after 6 months and 4-stroke after 3 months

• D.

All fuel should be thrown out after 6 months

B. 2-stroke mixtures should be thrown out after 3 months and 4-stroke after 6 months
Explanation
The correct answer states that 2-stroke mixtures should be thrown out after 3 months and 4-stroke fuel should be thrown out after 6 months. This is because 2-stroke engines typically have a higher oil-to-fuel ratio, which can cause the fuel to degrade more quickly. On the other hand, 4-stroke engines have a separate oil system and therefore the fuel tends to last longer. Therefore, it is recommended to dispose of 2-stroke mixtures after 3 months and 4-stroke fuel after 6 months to ensure optimal performance and prevent any potential issues caused by degraded fuel.

• A.

True

• B.

False

B. False
Explanation
This statement is false. In many places, a boat licence is required regardless of the motor size. The specific regulations regarding boat licences vary by jurisdiction, so it is important to check the local laws and requirements before operating a boat.
