Competence 2 (Deck)

A white light is the correct answer because it is required to be used with a vessel's whistle according to maritime regulations. This light helps to make the whistle's sound more noticeable and alert other vessels of the presence and position of the vessel. It is not limited to being used only at night, nor is it dependent on the whistle being broken or used prior to sounding the whistle.

The OIC-NW should report to the bridge in order to adjust his eyesight for at least 10 minutes prior to taking the watch. This is important because the OIC-NW needs to ensure that their vision is clear and focused before taking on the responsibility of navigating the vessel. Adjusting their eyesight allows them to have optimal visual acuity and reduces the risk of any errors or accidents while on watch.

When a vessel is overtaking another vessel on open waters and intends to pass without changing course, it is not required to sound any whistle signals. Whistle signals are typically used to communicate with other vessels and indicate the vessel's intentions or actions. In this case, since vessel "X" is passing without changing course, there is no need to sound any whistle signals as there is no change in the vessel's intended path.

The prohibition against displaying lights which may be confused with required navigation lights applies from sunset to sunrise and during restricted visibility. This is to ensure that vessels are easily visible and can be properly identified by other vessels to avoid collisions. Displaying lights that may be confused with required navigation lights during these times could lead to confusion and potential danger on the water.

A searchlight beam can be used by a vessel to attract attention. This powerful beam of light can be directed towards other vessels or towards the shore, making it highly visible and catching the attention of nearby individuals. It is a common practice to use searchlight beams to signal for help or to alert others of a vessel's presence or distress.

The correct answer is "Any available working lights to illuminate the decks." This is because a 200-meter vessel at anchor is required to display anchor lights, which are any available working lights that can illuminate the decks. The other options mentioned, such as the 225○ white light, 135○ white light, and all-round red or green light, are not specifically mentioned as lights shown by a vessel at anchor.

When a vessel is overtaking another vessel on open waters and will pass without changing course, it is not required to sound any whistle signals. Whistle signals are typically used to communicate the intentions and movements of vessels to avoid collisions. In this situation, since vessel "X" is passing without changing course, there is no need for any whistle signals as there is no risk of collision.

The word "seaplane" refers to any aircraft that is specifically designed to operate on water. This means that it can take off from and land on water, and it has the necessary features and capabilities to maneuver effectively in aquatic environments. It does not necessarily include commercial aircraft, airplanes flying over large bodies of water, or helicopters flying over water. The key defining characteristic is the ability to operate on water, making it distinct from other types of aircraft.

A vessel may use any sound or light signals to attract the attention of another vessel as long as the signal cannot be mistaken for a signal authorized by the Rules. This ensures that there is no confusion or misinterpretation of signals, which could potentially lead to accidents or misunderstandings between vessels. It is important for vessels to use signals that are distinct and not easily confused with the signals specified in the Collision Regulations to maintain clear communication and avoid any potential dangers at sea.

According to the International Regulations for Preventing Collisions at Sea (COLREGS), when a power-driven vessel encounters a fishing vessel, the power-driven vessel must keep out of the way of the fishing vessel. This is because the fishing vessel is engaged in fishing activities and has restricted maneuverability. Therefore, in this scenario, Vessel "A" must keep out of the way of Vessel "B" because "B" is fishing.

The vessel heading SSE means it is moving in the direction of south-southeast. The angle between the vessel's course and the south direction is 22.5 degrees (180 degrees - 157.5 degrees). Since the vessel is heading SSE, the course angle is in the clockwise direction from the south. Therefore, the correct answer is 157.5 degrees.

A look-out is best posted forward as low as possible because this position provides the widest field of vision and allows for early detection of any potential hazards or obstacles. Being positioned low also helps to minimize the effects of wind and other weather conditions, ensuring better visibility and reducing the risk of being obstructed by structures or equipment on the ship. Additionally, being forward allows for better communication with the bridge and other crew members, enabling quick response to any situations that may arise.

When making a course alteration to avoid collision, it is important to make a large change in the course. This is because a small change may not be sufficient to avoid the collision, especially if the other vessel is also making a course alteration. A large change in the course increases the chances of creating a safe distance between the two vessels. Additionally, making a large change in the course can help to clearly communicate the intention to the other vessel, reducing the risk of misinterpretation. Therefore, a large change is the most effective and recommended approach in such situations.

In this situation, hearing two prolonged blasts on the starboard quarter indicates that there is a vessel approaching from the starboard side. The appropriate action would be to hold your course and speed, as this indicates to the other vessel that you are maintaining your current path and speed, allowing them to safely pass on your starboard side. Altering course to port or starboard or stopping the engine could potentially create confusion and increase the risk of a collision.

A light used to signal passing intentions must be an all-round white light. This type of light is necessary to ensure visibility from all directions, indicating to other vehicles or pedestrians that there is an intention to pass. The use of a white light is important as it is easily distinguishable and can be seen clearly in different lighting conditions. The all-round aspect ensures that the light is visible from any angle, further enhancing safety on the road.

The Pre-departure Check List includes Navigational Equipment, Weather Report, and Passage Plan. However, it does not include Bridge standing Order. Bridge standing Order is a set of instructions that are specific to the bridge team and are usually posted in the bridge for reference. While it is important for the safe navigation of the vessel, it is not typically included in the pre-departure checklist.

When two vessels are meeting and will pass clear starboard to starboard, no whistle signal is required. This means that both vessels have a clear and safe passage, and there is no need for any audible signal to be sounded. The absence of a whistle signal indicates that the vessels have established visual contact and have agreed on a safe passing arrangement.

A vessel transferring cargo while underway is classified as "restricted in her ability to maneuver" because the act of transferring cargo can limit the vessel's ability to change course or speed quickly. This classification is important for other vessels to be aware of, as they need to give the restricted vessel enough space and take appropriate actions to avoid any potential collisions or accidents.

The correct answer is a signal meaning, "I am altering my course to starboard." This signal is required to be sounded by a power-driven vessel only when it is altering its course to starboard. It is a way for the vessel to communicate its intended maneuver to other vessels in the vicinity, ensuring safe navigation and avoiding collisions.

When the other vessel sounds one short blast, it indicates that they are altering their course to starboard (right). In this situation, since you are going to hold your course and speed, there is no need for you to sound any whistle signal. Therefore, the correct action is to sound no whistle signal.

As you approach the other vessel's stern, the vessels will drift together. This is because when you are overtaking a vessel in a narrow channel, the water displacement caused by both vessels moving in the same direction creates a suction effect between them. This suction effect causes the vessels to be drawn closer together, resulting in them drifting together.

The competence and vigilance of the officer of the watch are crucial in ensuring the safety of the vessel and its crew. By being competent and vigilant, the officer can identify and assess potential dangers or hazards, allowing them to take appropriate actions to avoid these situations. This includes making informed decisions, following established procedures, and effectively communicating with the crew. By avoiding dangerous situations, the officer of the watch plays a key role in maintaining the overall safety and security of the vessel.

Rule 16 of the International Regulations for Preventing Collisions at Sea (COLREGS) specifies the actions that a give-way vessel must take when encountering a stand-on vessel. This rule states that the give-way vessel should take early and substantial action to keep well clear of the stand-on vessel. It provides guidelines for the give-way vessel to alter its course and speed to avoid a potential collision.

The Night Orders Book is a document that contains specific instructions and guidelines for the crew to follow during nighttime operations on a ship. It covers various aspects of navigation and safety. The options given are all components that would typically be included in the Night Orders Book, except for "maintain ship's speed at all times." While maintaining an appropriate speed is important, it may not be explicitly mentioned in the Night Orders Book as it is usually covered by general navigation policies and regulations.

Four short blasts may be sounded ONLY by vessels in restricted visibility. This signal is used to indicate that a vessel is unsure about the intentions of another vessel and is used as a warning signal to alert nearby vessels of the potential danger. It is important for vessels to use this signal in restricted visibility situations to help prevent collisions and ensure the safety of all vessels involved.

An all-round white light is the correct answer for a light used to signal passing intentions. This type of light provides maximum visibility and can be easily seen from all directions. It is commonly used in marine navigation to indicate the presence of a vessel and its intentions to other vessels in the vicinity.

A vessel that is being towed would not emit a fog signal of one prolonged and two short blasts. Fog signals are typically used to indicate the presence of a vessel and its intentions. Being towed does not require such a signal as the vessel being towed is not maneuvering independently.

A vessel being towed would not sound a fog signal of one prolonged and two short blasts. This is because the responsibility of sounding the fog signal lies with the towing vessel, not the vessel being towed. The vessel being towed is considered to be under the control and responsibility of the towing vessel, so it does not need to sound its own fog signal.

Annex I of the Navigation Rules pertains to the positioning and technical details of lights and shapes. This annex provides specific guidelines on how vessels should display lights and shapes to indicate their position, size, and maneuverability. It helps to ensure that vessels can easily identify and interpret the lights and shapes displayed by other vessels, thereby promoting safe navigation and preventing collisions at sea.

Four short blasts may be sounded ONLY by vessels in restricted visibility. This signal is used to indicate that the vessel is unsure of the intentions of another vessel and is requesting it to confirm its own intentions. It is a precautionary signal used in situations where visibility is limited, such as in fog or heavy rain, to avoid collisions and ensure the safety of all vessels involved.

According to the given options, the statement that is true regarding equipment for bell and going signals is that manual sounding of the signals must always be possible. This means that regardless of the size of the vessel, it is necessary to have equipment that allows for manual sounding of the signals. This ensures that the vessel can communicate audibly with other vessels in various situations, such as when navigating in poor visibility or during emergencies.

A vessel shall navigate with caution at a speed commensurate with steerage way. Steerage way refers to the minimum speed at which a vessel can maintain controlled movement and steer in the desired direction. Navigating at this speed ensures that the vessel has enough control and maneuverability to avoid collisions and react to any unexpected situations. It is important for vessels to adjust their speed according to the conditions and maintain a speed that allows them to navigate safely.

When a power-driven vessel sounds two short blasts of the whistle, it indicates that the vessel is altering its course to port. This signal is used to communicate to other vessels that it intends to turn left and expects other vessels to give way accordingly.

When two vessels are in sight of one another and NOT in or near an area of restricted visibility, any of the following signals may be given EXCEPT four short whistle blasts.

When Vessel "P" sounds two short blasts on the whistle, it indicates that it is the stand-on vessel and expects Vessel "Q" to give way. In response, Vessel "Q" should sound five short and rapid blasts on the whistle to indicate that it acknowledges the signal and will take the necessary action to give way to Vessel "P". This is a standard signal used in the International Regulations for Preventing Collisions at Sea (COLREGS) to communicate between vessels and ensure safe navigation.

One short blast on the whistle is sounded ONLY by a vessel in sight of another as per the International Regulations for Preventing Collisions at Sea (COLREGS). This signal is used to indicate the vessel's intention to overtake another vessel on its starboard side. It is a way of communicating and ensuring safe navigation between vessels that are in close proximity to each other.

When two vessels are in sight of each other, they can use whistle signals to communicate their intentions and maneuvers. One short blast is a signal that indicates the vessel's intention to turn to starboard (right) side. This signal is commonly used to alert the other vessel that it intends to pass on the starboard side. By sounding one short blast, the vessel is indicating its intention to take the appropriate action to avoid a collision.

When a vessel is backing out of a slip in a harbor with restricted visibility, it should sound one prolonged blast only. This is the appropriate sound signal to indicate that the vessel is in reverse and is maneuvering to leave its current position. By sounding one prolonged blast, the vessel alerts other nearby vessels of its intentions and allows them to take necessary precautions to avoid a collision.

When pushing ahead in fog, a vessel towing shall sound one prolonged and two short blasts. This signal is used to indicate that the vessel is pushing ahead and is also towing another vessel or object. The prolonged blast is meant to alert other vessels of the towing vessel's presence, while the two short blasts indicate that the towing vessel is actively engaged in pushing ahead. This combination of signals helps to communicate the towing vessel's intentions and allows other vessels to take appropriate action to avoid a collision.

One short blast is sounded ONLY by a vessel in sight of another and NOT in or near an area of restricted visibility. This signal is used to indicate the intention of the vessel to overtake another vessel on its starboard side. It is a way of communicating the vessel's intention and ensuring safe navigation when there is clear visibility.
