Marine Navigation Lights & Rules Of The Road

A power-driven vessel underway refers to a boat or ship that is being propelled by an engine or motor and is currently in motion. This means that the vessel is not at anchor, not aground, and not engaged in any specific activities such as fishing or dredging. It is simply in transit, using its engine or motor to move through the water.

The day signal shown indicates that the vessel is engaged in towing. This means that the vessel is pulling or dragging another vessel or object behind it.

The correct answer is "all available means." This means that every vessel should use all the tools and resources at their disposal, such as radar, ARPA, ECDIS, and visual and auditory perception, to maintain a proper lookout. This ensures that they have a comprehensive understanding of the situation and can assess the risk of collision effectively.

A pilot vessel is a type of vessel that is used to transport pilots to and from ships in order to assist them with navigation in restricted or unfamiliar waters. These vessels are typically smaller in size and have specialized equipment to aid in their role as pilot boats. They are often operated by pilotage authorities or harbor authorities and play a crucial role in ensuring the safe passage of ships in and out of ports.

A vessel displaying a flashing blue light is likely a law enforcement vessel. Law enforcement vessels often use flashing blue lights to indicate their presence and authority while carrying out their duties, such as enforcing laws, conducting patrols, or responding to emergencies. The flashing blue light helps to alert other vessels and individuals to their presence and signifies that they are engaged in official law enforcement activities.

The correct answer is Two Red All-Round Lights, One Anchor Light, And Deck Lighting. This is because the question asks for the signals that should be displayed, and the given answer includes all the required signals based on the information provided in the picture. The two red all-round lights indicate the vessel's presence and position, the anchor light is necessary when the vessel is at anchor, and deck lighting helps to illuminate the deck area for safety purposes.

Rule 19 of Rules of the Road comes into effect when visibility is restricted. This means that the rule applies when there are conditions such as fog, rain, or darkness that limit the ability to see clearly. In these situations, it is important to follow the specific guidelines outlined in Rule 19 to ensure safe navigation and prevent accidents.

A vessel engaged in fishing, other than trawling, shall exhibit two all-round lights in a vertical line, the upper being red and the lower white, or a shape consisting of two cones with apexes together in a vertical line one above the other. This means that the correct answer is "Cone" because it is one of the options for the shape that can be used to exhibit the required lights.

The correct answer is "Power Vessel over 50M" because the question is asking for a category or type of vessel, and this option specifically refers to a powered vessel that is longer than 50 meters. The other options, such as "Hovercraft" and "Passenger Ferry," do not specify the size or length of the vessel, so they are not the correct answer. "Ship at Anchor" is also not the correct answer because it describes a specific situation or condition of a vessel, rather than a type or category.

The correct answer is "Dracone or partially submerged vessel or object being towed." This means that the vessel or object in question is either a dracone (a type of boat used for towing) or a partially submerged vessel or object being towed by another vessel.

Passing on the side with two diamonds is safe because diamonds represent a safe passage. The presence of two diamonds indicates that it is the designated safe side for passing the dredger.

A vessel constrained by her draft refers to a ship that is limited in its ability to maneuver due to its deep draft, which is the distance from the waterline to the bottom of the ship. This means that the ship is unable to change its course or speed easily, making it more vulnerable to collisions or other accidents. In this scenario, the vessel is likely operating in shallow waters where its draft restricts its movements, such as near a harbor entrance or a narrow channel.

A power-driven vessel underway but stopped and making no way through the water shall sound at intervals of not more than 2 minutes two prolonged blasts in succession with an interval of about 2 seconds between them.

The correct answer is that a vessel not under command should show two balls in a vertical line. One ball should be displayed to indicate that the vessel is not under command. This is in accordance with Rule 27, which states that a vessel not under command should exhibit three balls or similar shapes in a vertical line where they can best be seen.

When power-driven vessels are crossing, a signal of one short blast by either vessel means "I intend to leave you on my port side." This means that the vessel making the signal intends to pass the other vessel on its left side. This is in accordance with the International Regulations for Preventing Collisions at Sea (COLREGS), which provide guidelines for safe navigation and prevent collisions between vessels.

This answer is correct because it states that the vessel is towing astern with a tow length of 200 meters or less. This means that the vessel is pulling something behind it with a rope or cable that is shorter than 200 meters. This is a specific condition that describes the activity of the vessel, which differentiates it from the other options provided.

an alteration of course to PORT for a vessel forward of the beam, other than for a vessel being overtaken; .....Go to port, go to court.

The vessel is displaying the lights for a vessel aground. This means that the vessel is stuck or stranded on the ground or a shoal, and is unable to move. The lights are used to indicate to other vessels the vessel's position and status, and to warn them to keep clear.

False as an all-round white light or one ball should be displayed at the fore part of the vessel and not Mid ships

The correct answer is "Vessel aground." This means that the vessel is stuck or stranded on the ground or a submerged object, preventing it from moving or maneuvering. This can happen due to various reasons such as running aground on a sandbar, hitting a reef, or getting stuck in shallow waters. When a vessel is aground, it is unable to navigate or change its position until it is refloated or assisted by external means.
