Rule number 31 is titled "Seaplanes". This rule specifically addresses the actions that seaplanes should take to avoid collisions with other vessels. It provides guidelines on the lights and signals that seaplanes should display, as well as the right of way rules when encountering other vessels. This rule is important for ensuring the safety of both seaplanes and other vessels in shared waterways.

A vessel constrained by draft making way is required to display a black cylinder day shape. This day shape indicates to other vessels that the vessel has limited maneuverability due to its draft and is making way through the water. The black cylinder day shape is easily recognizable and helps other vessels to take necessary precautions while navigating near the constrained vessel.

Vessels that are less than 12 meters in length are not required to exhibit lights and shapes when aground. This means that if a vessel is grounded and its length is less than 12 meters, it does not need to display any lights or shapes to indicate its position and status to other vessels.

When the tow is more than 200 meters, both the tug and the vessel being towed will display the towing diamond. This is to ensure maximum visibility and alert other vessels of the towing operation. The towing diamond is a diamond-shaped symbol consisting of a yellow square with a black "T" inside, and it is used to indicate that a vessel is engaged in towing operations. By displaying the towing diamond on both the tug and the towed vessel, it helps to clearly communicate to other vessels in the vicinity that there is a towing operation underway and they need to exercise caution.

The correct answer is rule no. 30. Rule no. 30 in the context of the question is likely referring to the International Regulations for Preventing Collisions at Sea (COLREGS), which is a set of rules and regulations governing the conduct of vessels at sea. Rule no. 30 specifically deals with the responsibilities and actions to be taken by a vessel that is at anchor. It outlines the precautions that an anchored vessel should take to avoid collisions with other vessels, such as displaying the appropriate lights and signals.

If you are heading due east and observe a vessel's red light on your starboard beam, it means that the vessel is to the right of your direction of travel. Since the red light is on the right side, it indicates that the vessel is moving in the same direction as you, which is eastward.

A dredger at anchor at night is not required to show an anchor light. This is because dredgers are classified as special types of vessels and are exempted from displaying anchor lights.

The correct answer is rule 33 because it provides the most comprehensive and specific explanation for the equipment used for sound signals. This rule likely covers all the necessary guidelines and specifications for sound equipment, ensuring that they meet the required standards for effective sound signal transmission. Rules 32, 31, and 35 may touch on related topics, but they are not as focused or relevant to the specific question of equipment for sound signals.

When a vessel is underway but stopped on the water, it is an indication that the vessel may be anchored or moored. In this situation, the correct sound signal to be sounded as an officer on watch is two long blasts. This signal is used to indicate that the vessel is not under command and is unable to maneuver as required by the International Regulations for Preventing Collisions at Sea (COLREGS).

In restricted visibility, such as in fog or heavy rain, a gong should be sounded for a duration of 5 seconds. This is an important safety measure to alert other vessels of the presence and position of the ship, helping to prevent collisions. Sounding the gong for not more than 5 seconds ensures that the sound signal is clear and easily distinguishable in adverse weather conditions.

In restricted visibility, it is important to take necessary actions to avoid collisions. Reducing speed would be the best course of action in this situation as it allows more time to assess the situation and react accordingly. By reducing speed, the vessel can also minimize the risk of collision and give other vessels more time to respond to its presence.

The signal "1 long 1 short 1 long 1 short blast on the whistle" will not be considered as a signal to attract attention because it does not follow the standard signaling patterns. In maritime communication, specific signals and patterns are used to convey messages and attract attention. The correct signaling pattern for attracting attention is typically a series of long blasts or a combination of long and short blasts. Therefore, the given signal does not adhere to the recognized patterns and will not be considered as a signal to attract attention.

When a vessel is aground, it means that it is stuck or stranded on the ground or a submerged object. In this situation, to distinguish the vessel from an anchored vessel, it is required to display additional light signals. According to the International Regulations for Preventing Collisions at Sea (COLREGs), a vessel aground should display three red lights in a vertical line. This signal helps other vessels to recognize the vessel's predicament and take appropriate action to avoid a collision. The other options, such as two white lights in vertical or two red lights, do not specifically indicate a vessel aground and may cause confusion for other vessels.

In restricted visibility, a pushing vessel in a composite unit would sound two long blasts as a warning signal. This signal is used to indicate that the pushing vessel is pushing ahead and is unable to maneuver effectively. The two long blasts serve as a warning to other vessels in the vicinity to exercise caution and take appropriate action to avoid a potential collision.

A vessel engaged in fishing shows the same light signal when underway or at anchor. This is because fishing vessels are required to display the same lights as a vessel at anchor when they are not making way. This signal helps other vessels to identify and navigate around fishing vessels, ensuring safety at sea.

The correct answer is "none" because there is no minimum length of a diving operation vessel that is not required to exhibit a code flag "A". This means that all diving operation vessels, regardless of their length, are required to exhibit the code flag "A".

A tugboat without a tow will produce a sound signal of 1 long blast. This signal is used to indicate that the tugboat is not actively engaged in towing any vessel.

When you are dead astern of a pilot vessel on pilotage duty, the correct lights that are visible are all around white over red lights and a stern light. The all around white over red lights indicate that the vessel is engaged in pilotage duty, while the stern light is a white light that is visible from behind the vessel. This combination of lights helps other vessels understand the role and position of the pilot vessel, ensuring safe navigation and avoiding collisions.

The sound signal of one long blast followed by four short blasts indicates that the vessel is a pilot vessel (P.V.). Pilot vessels are used to transport pilots to and from ships in order to assist with navigation in restricted visibility or congested areas. The specific sound signal is a recognized signal used by pilot vessels to communicate their presence and intentions to other vessels.

The appropriate sound signal to be sounded by a W.I.G. (Wing In Ground) in restricted visibility is not specified in the given options. Therefore, none of the above options is the correct answer.

When a vessel is aground, it is stuck or stranded on the ground or a submerged object. To distinguish itself from an anchored vessel, the aground vessel should sound three strikes before and after a rapid ringing of the bell. This additional signal helps to alert other vessels in the vicinity that the vessel is in a potentially hazardous situation and requires assistance or caution.

The correct answer is "side light and all round red white red in vertical." When a R.A.M. (Restricted in Ability to Maneuver) vessel is underway and less than 12 meters in length, it should display a side light on the starboard side and an all-round red white red light in a vertical line. This configuration helps other vessels determine the vessel's status and navigate safely around it. The other options listed are incorrect because they either do not include the required lights or include lights that are not applicable to a R.A.M. vessel.

In dense fog, it is important to take appropriate actions to avoid a collision. Sounding one long blast on the horn is the correct response in this situation. This is the signal for a power-driven vessel to indicate its presence and warn other vessels of its position. By sounding one long blast, the vessel is alerting the other vessel to its presence and allowing it to take necessary action to avoid a collision.

The correct answer is an all around white masthead light. This light should be displayed on the masthead for a pilot who is not engaged in pilotage duty while underway. The all around white light ensures visibility and signals to other vessels that the pilot is not currently involved in pilotage duties.

When a power-driven vessel is stopped in the water during restricted visibility, it should sound two long blasts as an appropriate sound signal. This signal indicates to other vessels that the power-driven vessel is not underway and is stationary. By sounding two long blasts, the vessel is alerting nearby vessels of its presence and allowing them to take necessary precautions to avoid a collision.

A vessel towing and unable to deviate from her course is not required to exhibit R.A.M. (Restricted in Ability to Maneuver) lights and shapes when in operation. This is because such a vessel is considered to have limited maneuverability and is unable to change its course, making it exempt from the requirement of displaying R.A.M. lights and shapes.

An ordinary sailing vessel propelled by machinery will produce a sound signal of 1 long blast. This signal is used to indicate the vessel's intention to maneuver to starboard (right) side. It is important for vessels to communicate their intentions through sound signals to avoid collisions and ensure safe navigation.

The interval between sound signals of a sailing vessel in restricted visibility should not exceed 2 minutes. This is important for safety purposes, as it allows other vessels to be aware of the presence and location of the sailing vessel. If the interval were longer than 2 minutes, it would increase the risk of collisions or other accidents, as other vessels may not be able to accurately determine the sailing vessel's position. Therefore, it is crucial for the sailing vessel to emit sound signals at regular intervals, ensuring that other vessels can navigate safely in restricted visibility conditions.
