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.

A vessel traveling at a speed at which any sudden danger can be avoided is considered safe. This means that the vessel is traveling at a speed that allows the operator to have enough time to react and take necessary actions to avoid any unexpected dangers or hazards that may arise. By maintaining a speed that allows for quick maneuverability, the vessel can navigate safely and reduce the risk of accidents or collisions.

Navigation lights are required to be switched on and displayed on a vessel underway from sunset to sunrise and in restricted visibility. This is to ensure the safety of the vessel and other vessels in the vicinity. By having navigation lights on, other vessels can easily identify the position, direction, and size of the vessel, especially during low visibility conditions. It helps in preventing collisions and maintaining proper navigation protocols. Therefore, it is essential to switch on and display navigation lights during these specific times.

The master (driver) of a vessel is responsible for maintaining a proper lookout and avoiding collisions to ensure the safety of everyone on board. Additionally, they are also responsible for ensuring that all safety equipment is accessible and stored correctly on the vessel. Therefore, the correct answer is "All of the above."

All vessels need to have or display lights at night in order to ensure visibility and prevent collisions. This is important for the safety of all vessels, as well as for other boats and ships in the vicinity. Lights help to indicate the presence, position, and direction of a vessel, allowing other vessels to navigate safely and avoid potential accidents. Therefore, it is a requirement for all types of vessels, including power driven vessels, canoes and rowboats, and sailing vessels, to have or display lights at night.

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.

When traveling upstream, it is important to keep the navigation mark on your starboard (right hand) side to stay in the channel. This is because the navigation marks are designed to indicate the correct path for boats, and keeping the mark on the starboard side ensures that you are staying on the correct side of the channel. By doing so, you can avoid straying into shallow or hazardous areas and maintain a safe and navigable route.

Sail vessels, operating only under sail, have the right of way over a power-driven vessel at all times, unless they are overtaking the power vessel or if the power vessel is displaying an orange diamond. This means that sail vessels have priority over power vessels in most situations, but they must yield if they are overtaking another vessel or if the power vessel is indicating that it requires right of way by displaying an orange diamond.

This navigation mark is classified as a special mark. Special marks are used to indicate specific areas or features that require special attention or caution, such as underwater cables, pipelines, wrecks, or military exercise areas. They are typically yellow or yellow with a top mark, and their purpose is to inform mariners about potential hazards or restricted areas.

An isolated danger mark is used to indicate a single isolated danger, such as a rock or wreck, which has navigable water all around it. This type of navigation mark is placed to warn mariners to keep clear of the danger and to indicate the best navigable water to pass around it. It is typically colored black with two broad horizontal red bands and has two black spheres on top.

When driving your vessel within a No Wash Zone, it is necessary to travel at a speed which creates minimal wash to ensure that your wash does not affect other people or vessels. This means that you should be cautious and mindful of the impact your vessel's movement may have on the surrounding environment and other watercrafts. By reducing the wash, you are minimizing the disturbance caused by your vessel and promoting safety and consideration for others in the area.

Assuming the Heat Escape Lessening Posture (HELP) and not removing clothing can help extend survival time in cold water. This posture involves bringing the knees to the chest and crossing the arms tightly over the chest to minimize heat loss. By doing so, the body's heat is conserved, and the risk of hypothermia is reduced. Removing clothing or staying still can increase heat loss and decrease survival time in cold water.

Cardinal marks are used to indicate the safest and deepest navigable water in a particular area. They provide information about the direction in which vessels should navigate to avoid potential dangers such as shallows, rocks, or wrecks. Each cardinal mark is associated with a compass direction (north, south, east, or west) and indicates that deeper water can be found in that direction away from potential hazards. Therefore, cardinal marks help mariners navigate safely by guiding them towards deeper waters and away from danger.

This navigation mark indicates that deeper water lies to the east.

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.

When travelling upstream at night, keeping a flashing green light on your starboard (right hand) side helps you stay within the channel. This is because the flashing green light indicates the starboard side of the channel, and by keeping it on your right, you ensure that you are staying within the designated path of the channel.

By observing the effects of your wash and adjusting your speed as necessary, you can ensure that your boat's wash does not excessively impact on foreshores or other vessels. This means being aware of the waves and turbulence caused by your boat's movement and making necessary adjustments to your speed to minimize the impact. It requires being attentive and responsive to the conditions and surroundings, prioritizing the safety and well-being of other vessels and the environment.

When navigating through a mooring area, it is important to keep a lookout for people and objects in the water to ensure their safety and avoid any collisions. Traveling at a safe speed is crucial to maintain control of the vessel and reduce the risk of accidents. Additionally, keeping wash to a minimum is necessary to prevent any damage to other vessels or objects in the area. Therefore, all of the given options are correct and should be followed when navigating through a mooring area.

When driving a vessel at high speed, sudden vision impairment due to sun or spray can be dangerous. The correct immediate reaction would be to slow down or stop. This allows the driver to regain clear vision and assess the situation properly before continuing. Continuing at speed or increasing speed could lead to accidents or collisions, as the driver may not be able to see potential hazards or obstacles in their path. Altering course to port and continuing at speed is also not advisable, as it does not address the issue of impaired vision.

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 outward journey, another third for the return journey, and keep the remaining third as a reserve. This ensures that there is enough fuel for the entire trip, with a safety margin in case of any unforeseen circumstances or emergencies.

When overtaking another vessel, it is important to keep well clear of its way. This means maintaining a safe distance and avoiding any potential collision. By keeping clear, you ensure the safety of both vessels and reduce the risk of accidents. Waiting for the vessel to slow down or passing on either side may not guarantee a safe overtaking maneuver, so it is best to keep a safe distance and proceed with caution.

In this situation, the correct call to the local marine rescue association would be "PAN PAN." "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.

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.

When using navigational leads, it is important to line them up, one behind the other. Navigational leads are used to guide vessels through narrow or shallow channels, indicating the correct path to follow. By lining them up, one can ensure that they are following the intended route and avoiding any potential hazards. This helps in maintaining the safety and efficiency of navigation.

Driving a boat in shallow weedy areas should be avoided for environmental reasons because these areas may contain endangered seagrasses. Seagrasses play a crucial role in maintaining the health of marine ecosystems as they provide food and habitat for various species, filter water, and prevent erosion. Driving a boat in these areas can cause damage to the seagrasses by uprooting or damaging them, which can disrupt the delicate balance of the ecosystem and harm the species that depend on them for survival. Therefore, it is important to avoid driving boats in shallow weedy areas to protect and preserve these endangered seagrasses.

Vessels should be driven on the starboard (right-hand) side in a channel. This is because the International Regulations for Preventing Collisions at Sea (COLREGS) state that vessels should keep to the starboard side to avoid collisions. By driving on the starboard side, vessels can maintain a consistent and predictable path of travel, reducing the risk of accidents and allowing for safe navigation in narrow channels.

When you see a vessel ahead of you exhibiting these lights, you should alter your course to starboard (right). This is because the vessel ahead is showing the red light on its port (left) side and the green light on its starboard (right) side. According to the International Regulations for Preventing Collisions at Sea (COLREGS), when two power-driven vessels are approaching each other head-on, both vessels should alter their course to starboard to pass each other safely. By altering your course to starboard, you ensure that you are passing the other vessel on its port side, which is the correct and safe maneuver.

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.

The part of the boat labelled A in the diagram is the freeboard. Freeboard refers to the distance between the waterline and the upper deck level of the boat. It is important for the stability and buoyancy of the boat, as it helps to prevent water from entering the vessel.

The safety label of a power-driven vessel must be displayed where it can be clearly seen from the steering position. This ensures that the operator of the vessel can easily refer to the safety label for important information and instructions while operating the vessel. Placing the safety label in a visible position from the steering position enhances safety and compliance with regulations.

This sign indicates that boaters should maintain a speed that does not generate waves that could cause damage to other vessels or be a nuisance to others. It serves as a reminder to be considerate and mindful of the potential impact of their speed on the surrounding environment and other water users.

Passing on any side of the light but not too close is the correct answer because a white light flashing in groups of two is typically used to indicate a level crossing or a pedestrian crossing. In such situations, it is important to proceed with caution and not pass too close to the light to ensure the safety of pedestrians or vehicles crossing the road.

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.

The correct answer is "Draught." In boating terminology, the term "draught" refers to the depth of a boat's hull below the waterline. It is often measured from the waterline to the lowest point of the boat's keel. The draught of a boat is an important measurement as it determines the boat's stability, maneuverability, and the areas it can navigate safely.

A navigational marker showing a white light flashing quickly in groups of nine flashes indicates that deeper water is to the west.

When driving a power vessel at 10 knots or more or towing a person, the minimum distance both the vessel and the towed person must keep from a non-powered vessel or a person in the water is 60 metres. If it is not possible to maintain this distance, they must keep a safe distance.

The correct answer is "Maximum of three people." This means that the number of persons allowed to be towed behind a vessel should not exceed three. This is a safety regulation to ensure that the vessel is not overloaded and that the towing apparatus can handle the weight and strain of the people being towed. It is important to adhere to this limit to prevent accidents and ensure the safety of everyone involved.

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.

The minimum length of a tow rope for towing operations in waterskiing is 7 metres. This length is necessary to ensure that the skier is at a safe distance from the boat, reducing the risk of collision or getting caught in the propeller. It also allows for proper maneuverability and control while skiing. A shorter tow rope could increase the chances of accidents and injuries.

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.

An efficient sound signalling device is required to be carried on all vessels. This is because sound signals are vital for communication and safety purposes on the water. Regardless of the type or size of the vessel, having a sound signalling device ensures that the vessel can effectively communicate its intentions to other vessels, especially in situations where visibility may be limited. Therefore, it is necessary for all vessels to have an efficient sound signalling device on board.

A deep V hull is the best type of boat for handling adverse conditions on a bar. The deep V shape of the hull allows the boat to cut through waves and rough water more efficiently, providing a smoother and more stable ride. This design also helps to prevent the boat from capsizing or taking on water in challenging conditions. The other options, such as the punt, shallow V, and displacement hull, are not as well-suited for adverse conditions on a bar as they may not have the same level of stability and wave-cutting ability as a deep V hull.

In open water, it is mandatory to carry Lifejacket Level 100+ (Type 1's) for each person onboard. This type of lifejacket provides the highest level of buoyancy and is specifically designed for use in offshore or rough water conditions. It ensures that individuals have the necessary flotation and support to stay afloat and survive in potentially dangerous situations.

When travelling downstream at night, keeping a flashing red light on your starboard (right hand) side will help you stay within the channel. This is because the red light indicates the right side of the channel when moving in the direction of the sea. By keeping the light on the starboard side, you ensure that you are on the correct side of the channel and avoid straying into shallow or dangerous areas.

The correct answer is "Two red all-round lights, one anchor light and deck lighting." This is the appropriate signal to be displayed based on the information provided.

The registration label on a powered vessel must be displayed on the port (left hand) side where it is clearly visible. This ensures that other boaters and authorities can easily identify and verify the registration of the vessel. By having a standardized location for the registration label, it helps maintain consistency and makes it easier for everyone to comply with the regulations.

Crossing a coastal bar on an outgoing tide (ebb tide) is considered the most dangerous time because the water is flowing out of the bar and can create strong currents and breaking waves. This can make it difficult for boats to navigate through the bar and increase the risk of capsizing or getting caught in the turbulent water. It is generally safer to cross during slack water when the tide is neither incoming nor outgoing, as the currents are weaker and the water is calmer.

The given statement is correct because it states a specific measurement of the tidal range on a specific date, which is 2.1 meters on the 22nd of June.
