Road Rules 1dpa 70

When a vessel is said to be in sight of one another, it means that the navigational lights of both vessels are visible to each other at night. This is an important safety measure to ensure that vessels can avoid collision and navigate safely. Therefore, the statement "A vessel is said to be in sight of one another when you can see the navigational lights at night" is true.

A vessel that is experiencing exceptional circumstances, such as being unable to maneuver due to mechanical failure or being caught in adverse weather conditions, is considered as a vessel not under command. This means that the vessel cannot follow the normal rules of navigation and other vessels should give it the right of way and take necessary actions to avoid a collision. Therefore, the statement "A vessel on a condition of having exceptional circumstances is considered as vessel not under command" is true.

This statement is true because it is a basic rule of navigation that a vessel should always be able to stop within a safe distance in order to avoid collisions or other dangerous situations. The speed at which a vessel can safely stop will depend on factors such as the size and maneuverability of the vessel, weather conditions, visibility, and the presence of other vessels or obstacles. By proceeding at a safe speed, a vessel can ensure that it has enough time and distance to react and take appropriate action if necessary.

The statement is true because when an OOW (Officer of the Watch) is unsure or doubtful about a situation, it is important for them to act accordingly. This means that they should take appropriate actions based on their training and experience to ensure the safety of the vessel and its crew. Acting accordingly in such situations helps to minimize the risk of accidents or incidents at sea.

When a vessel is being overtaken by another vessel, the overtaken vessel is required to keep clear and allow the overtaking vessel to pass safely. However, once the overtaking vessel has successfully passed and is no longer in a position to collide with the overtaken vessel, the overtaken vessel is relieved of its obligation to keep clear. Therefore, the statement is true.

The statement is true because a vessel constrained by draft refers to a ship that is limited in its ability to maneuver due to its draft or depth in the water. These vessels are often large and have a deep draft, which restricts their ability to change course or avoid collisions easily. Therefore, they may be unable to keep out of the way of another vessel to avoid a collision, making the statement true.

When a vessel approaches another vessel from an angle greater than 22.5 degrees forward of the overtaken vessel's beam, it is considered to be an overtaking vessel. In other words, if the approaching vessel is coming from a position that is more towards the front of the overtaken vessel rather than from the side, it is classified as an overtaking vessel.

When there is a risk of collision, a vessel may choose to reduce its speed in order to avoid a close quarter situation with another vessel. This means that if slowing down will help prevent a potential collision, it is a recommended action. However, it is important to note that reducing speed should only be done if it will not create another hazardous situation.

The statement is suggesting that if another vessel has limitations, it may be necessary for your vessel to depart from the rule. This implies that there are situations where following the rule may not be feasible or safe due to the limitations of another vessel. Therefore, the statement is true as it highlights the possibility of departing from the rule under certain circumstances.

A special rule made by any state can interfere with an international rule regarding ship design and construction. This is because states have the authority to create their own rules and regulations, which may differ from international standards. Therefore, if a state decides to implement a special rule regarding ship design and construction, it can potentially contradict or override the international rule on the same subject.

The term "high seas" in the international regulation for preventing collision at sea refers to the open sea. This term is used to describe the waters that are not under the jurisdiction of any specific country and are considered to be international waters. It is important for ships and vessels to understand and follow the regulations in these areas to ensure safe navigation and avoid collisions. The term does not refer to the depth of the water, coral reefs, or dockyards, but specifically to the open sea.

R.A.M. stands for Restricted in Ability to Maneuver. This means that the vessel is unable to keep out of the way of other vessels due to the nature of her work. Restricted in Ability to Maneuver vessels are typically large, slow-moving ships such as tankers or cargo ships that require a significant amount of time and space to change course or stop. This restriction is usually due to the vessel's size, draft, or the nature of the cargo it is carrying.

Anchoring is not allowed in the TSS on its termination of the lane. This means that once a vehicle reaches the end of the lane, it is not permitted to anchor or stop in that area.

The statement indicates that all vessels are permitted to use the traffic separation scheme. This means that regardless of the type or size of the vessel, they are allowed to navigate within the designated traffic separation scheme.

Long range scanning in the operation of radar is necessary for collision avoidance because it provides an early warning system. By scanning a wide area, radar can detect potential collisions at a distance, allowing for more time to take evasive action and prevent accidents. This early warning system is crucial for collision avoidance as it helps to prevent delays in approaching objects and ensures that standard operating procedures are followed to maintain safety.

Rule 12 of the International Regulations for Preventing Collisions at Sea (COLREGS) states the conduct of sailing vessels. It outlines the right of way for sailing vessels, stating that they have the right of way over motorized vessels in certain situations. This rule helps to ensure the safety and proper navigation of sailing vessels in relation to other vessels at sea.

A fishing vessel should keep clear of a R.A.M. (Restricted in Ability to Maneuver) vessel. This is because a R.A.M. vessel is limited in its ability to maneuver due to its size, shape, or draft. As a fishing vessel, it is important to avoid any potential collision or interference with other vessels, especially those that have restricted maneuverability.

This topic is best discussed under Rule 7 of the International Rule on Preventing Collision at Sea. Rule 7 states that every vessel shall use all available means to determine if risk of collision exists, including the use of radar. If a vessel is observed on radar and its bearing does not change while closing in, it indicates a potential risk of collision and the appropriate actions should be taken to avoid it.

A sailing vessel can be treated as a power driven vessel when she is using her propulsive power. This means that she is no longer relying solely on wind power to move and is instead using her engine or motor to propel herself. In this state, she will be subject to the rules and regulations that apply to power driven vessels rather than those that apply to sailing vessels.

The statement is true because the term "underway" refers to a vessel that is in motion or moving on the water. It does not matter if the vessel is completely stopped or moving slowly, as long as it is on the water, it is considered underway.

As a vessel engaged in fishing, you are allowed to lay your net in the traffic separation lane or zone. This is because the traffic separation scheme is specifically designed to separate opposing streams of traffic and ensure the safe and efficient flow of vessels. However, it is important to note that you must still follow Rule 18, which requires you to avoid impeding the passage of other vessels and take necessary actions to prevent collisions.

Rule 17 of the International Regulations for Preventing Collisions at Sea (COLREGS) actually states that the stand-on vessel must maintain its course and speed unless it is apparent that the give-way vessel is not taking appropriate action to avoid a collision. In this case, the stand-on vessel may take action to avoid the collision. Therefore, the given statement is false.

To cross a traffic scheme from the side at a right angle means to approach the intersection perpendicularly to the opposite traffic lane. This ensures a safer and more efficient maneuver as it allows for better visibility and reduces the risk of collisions with oncoming traffic. By crossing at a right angle, the driver can navigate the intersection smoothly and minimize the chances of causing any disruptions or accidents.

When a vessel is proceeding at a safe speed, it needs to consider various factors to ensure its safety. These factors include the draught of the vessel in relation to the depth of the water, traffic density, and restricted visibility. However, night time is not a factor that needs to be considered separately, as it falls under the category of restricted visibility. Therefore, the correct answer is night time.

Radar can be used in any condition of visibility because it is capable of detecting and tracking objects even in low visibility situations such as fog, rain, or darkness. It provides valuable information about the position, speed, and direction of other vessels or objects in the vicinity, enhancing situational awareness and aiding in collision avoidance. Therefore, radar is not limited to being used only in restricted visibility but can be utilized in any weather or visibility condition to improve navigation safety.

Rule 8 of the International Regulations for Preventing Collisions at Sea (COLREGS) is the best rule to discuss the statement "positive, ample time and performance of good seamanship." Rule 8 states that "any action taken to avoid collision shall be taken in accordance with the Rules of this Part and shall, if the circumstances of the case admit, be positive, made in ample time and with due regard to the observance of good seamanship." This rule emphasizes the importance of taking timely and decisive actions to avoid collisions while also considering the principles of good seamanship.

The best action to avoid collision when there is enough sea room is to alter the course. By changing the direction of the vessel, it creates a greater distance between the two objects and reduces the risk of a collision. This action is effective when there is sufficient space to maneuver and allows for a safe passage without the need to reduce speed or sound signals.

When there is immediate danger is considered the best reason for departing from the rule under Rule no. 2 paragraph b. This is because the safety of the vessel and its crew is of utmost importance, and if there is an immediate danger that could potentially harm the vessel or its occupants, it is necessary to deviate from the rule in order to avoid the danger and ensure the safety of everyone on board.

A vessel engaged in fishing is restricted to maneuver due to her fishing gear. This means that the fishing gear, such as nets or lines, can limit the vessel's ability to change direction or avoid obstacles. The fishing gear may be spread out in the water, making it difficult for the vessel to navigate freely. Therefore, the vessel is unable to keep out of the way of another vessel or maintain a clear path.

The correct answer is "mine clearing vessel because of her condition." In a crossing situation, the stand on vessel is typically the vessel that is less maneuverable or restricted in its ability to change course or speed. Since the mine clearing vessel is involved in a specific task and may have limited maneuverability due to its equipment or operations, it is considered the stand on vessel in this situation.

Rule number 16 in the context of maritime regulations pertains to the actions that should be taken by the vessel that is required to give way to another vessel. This rule outlines the specific responsibilities and obligations of the give-way vessel in terms of altering its course or speed to avoid a potential collision. It emphasizes the importance of taking timely and appropriate actions to ensure the safety of both vessels involved.

In an overtaking situation in a narrow channel, the sound signal of one long blast followed by one short blast, repeated in the same sequence, is used. This signal indicates that the overtaken vessel agrees with the overtaking vessel's intention to pass and gives its consent for the maneuver.

The correct answer is False. This statement is incorrect because multiple vessels can navigate safely in the fairway of a narrow channel. The fairway is designed to accommodate the passage of multiple vessels, and as long as they are following the proper rules and regulations, they can all use the channel safely.

When an action by a give way vessel is done early and substantial, it means that the vessel takes prompt and significant measures to avoid a collision. By altering its course to port (left), the give way vessel effectively shows its intention to yield and allows the stand on vessel to maintain its course and speed. This early and substantial action helps in preventing a potential collision and ensures the safety of both vessels.

When approaching an obscured bend and encountering another vessel on the opposite side of the channel, it is appropriate to maintain course and speed. By doing so, you are indicating that you will continue on your current path and are making your presence known to the other vessel. Additionally, sounding one long blast will further alert the other vessel of your presence and help prevent a potential collision.

When determining safe speed, factors such as the presence of background light, state of visibility, and maneuverability of the vessel are important to consider. However, the length and width of the vessel itself does not directly impact the safe speed. The size of the vessel may affect other aspects such as stability and handling, but it is not a determining factor in setting the safe speed.

As a stand on vessel, your possible action would be to maintain your course and speed. This is because the vessel who is required to keep out of the way of another is already taking appropriate action in the crossing situation. By maintaining your course and speed, you are allowing the give-way vessel to navigate around you safely. Altering course to port towards the other vessel or increasing your speed could potentially create confusion and increase the risk of a collision. Sounding an appropriate signal for a crossing situation is not necessary in this scenario as the other vessel is already taking appropriate action.

In an overtaking situation, the rule that shall prevail is the overtaking followed by crossing rules. This means that the vessel that is overtaking another vessel has the responsibility to keep clear and avoid crossing the bow of the vessel being overtaken. The vessel being overtaken has the right of way and should maintain its course and speed. This rule helps to ensure safety and prevent collisions during overtaking maneuvers.

When a vessel is overtaking another vessel, it is required to exhibit either the green or the red lights. These lights are known as the sidelights and are visible from the overtaken vessel when the overtaking vessel is within the 22.5 degrees abaft the beam. The purpose of these lights is to indicate the direction in which the overtaking vessel is approaching from. Therefore, the correct answer is either the green or the red lights.

This condition does not define a vessel constrained by draft because being in deep water does not impose any restrictions or limitations on the vessel's draft. The draft of a vessel refers to the vertical distance between the waterline and the deepest part of the vessel below the water's surface. In deep water, the vessel has sufficient depth to navigate without any concerns about draft limitations. Therefore, this condition is not relevant to defining a vessel constrained by draft.

Slackening your speed would be a possible action to avoid collision in restricted visibility if you hear a fog signal forward of your port beam. By reducing your speed, you give yourself more time to assess the situation and react accordingly. This can help prevent a potential collision and give you more control over your vessel in the limited visibility conditions.

The vessel constrained by draft is the stand on vessel because it is restricted in its ability to maneuver due to its draft. As a power-driven vessel, you have the responsibility to give way to the stand on vessel. This is because the stand on vessel has the right of way in this situation.

A vessel can be considered "in sight" if it can be seen visually from the bridge. This means that the officer on navigational watch is able to physically see the vessel with their own eyes. This is the most reliable way to confirm the presence of another vessel and ensure safe navigation.

In a crossing situation, the stand on vessel is indeed relieved of her obligation to give a wide space after a give way vessel has made an action. The stand on vessel has the right of way and the give way vessel must take appropriate action to avoid a collision. Therefore, the correct answer is False.

A crossing vessel does not sound the appropriate signal of one line blast when she intends to cross another. The appropriate signal for a crossing vessel is two short blasts, not one long blast. Therefore, the statement is false.

In a crossing situation, when a stand on vessel has already taken avoiding action, the best action for the give way vessel would be to give a wide space. This means that the give way vessel should alter its course or speed in order to create a significant distance between the two vessels, ensuring a safe passage and avoiding any potential collision. This action allows both vessels to navigate the crossing situation without any risk or interference.

When crossing a narrow channel, it is important to keep clear of the vessel that is navigating safely through the channel. This means giving the right of way to the vessel that is already in the channel and ensuring that there is enough distance between your vessel and the navigating vessel to avoid any potential collisions or interference with its path. By keeping clear, you are prioritizing the safety and navigation of the vessel that is already in the narrow channel.

False. In a head-on situation, both vessels are required to alter their course to starboard (right) to avoid a collision. They should also reduce their speed and maintain a safe distance between each other. This is stated in the International Regulations for Preventing Collisions at Sea (COLREGS) Rule 14. Therefore, it is incorrect to say that one vessel is directed to keep clear while the other maintains her course and speed.
