There are several sound signals for a vessel underway in restricted visbility.
- A power drivel vessel underway, making way- 1 PROLONGED Blast (4-6 seconds duration) Not to exceed every two minutes.
- A power driven vessel underway NOT making way-2 PROLONGED every 2 minutes, not exceed two minutes.
- A vessel not under command, a vessel restricted in maneuverability, a vessel towing, a vessel engaged in fishing, a sailing vessel & a vessel constrained by her draft (International only) 1 PROLONGED blast followed by two short blast (duration about 1 second per short blast) every two minutes, not to exceed two minutes.
- A MANNED vessel being towed shall sound 1 PROLONGED followed by 3 SHORT blasts every two minute, not to exceed two minutes.
See the link provided for the International and Inland Navigational Rules of the Road. Rule 35.
for power driven vessels over 12meters it's one long blast every 2 minutes
What else can I help you with?
Which vessel sounds the same fog signal when underway or at anchor?
A vessel that sounds the same fog signal whether underway or at anchor is a sailing vessel. According to the International Regulations for Preventing Collisions at Sea (COLREGs), a sailing vessel under sail alone is required to sound one prolonged blast followed by two short blasts. This signal is used to indicate its presence and position in reduced visibility conditions, regardless of its status.
What sound signal indicates that a sailing vessel is underway in the fog?
One prolonged blast followed two short blasts, every two minutes, not to exceed two minutes. Rule 35-Sound Signals in restricted visibility.
What sound signal should a powerboat give underway in fog?
A powerboat underway in fog should sound a prolonged blast on its horn at intervals of not more than two minutes. This signal alerts other vessels to its presence in low visibility conditions. Additionally, if the vessel is maneuvering or making way, it may also sound short blasts as required for specific maneuvers. Always be prepared to adjust your signals based on the surrounding conditions and the presence of other vessels.
What sound signal indicates a sailing vessel is underway in the fog and how frequently?
Rules of the RoadRule 35Sound Signals in Restricted Visibility(C) A vessel not under command, a vessel restricted in her ability to maneuver, a vessel constrained by her draft, a sailing vessel, a vessel engaged in fishing, and a vessel engaged in towing or pushing another vessel shall..........sound at intervals of not more than two minutes, three blast in succession, namely one prolonged followed by two short blasts.
You are out on the water in foggy conditions You hear one prolonged blast every two minutes What does this sound signal mean?
I am a power-driven vessel underway. Sound signals let other boaters know where you are located during periods of restricted visibility, such as extreme fog. If you hear the fog signal of a vessel you cannot see, slow to a minimum speed until you are sure there is not a risk of collision. One prolonged blast at intervals of not more than two minutes is the signal used by power-driven vessels when underway.

What sound signal indicates that a power-driven vessel is underway in the fog?
A power-driven vessel under way sounds one prolonged blast not less than every two minutes. However if it is less than 12meters in length it is not required to give any signal.
A sailboat is underway fog what signal do you hear?
When a sailboat is underway in foggy conditions, it is required to sound a fog signal. The typical sound is one prolonged blast every two minutes, which warns other vessels of its presence. Additionally, if the sailboat is under sail alone, it may also sound three short blasts to indicate its inability to maneuver as a power-driven vessel would. These signals help ensure safety by alerting nearby boats to the sailboat's location.
A power boat is underway in fog what sound do you hear?
When a power boat is underway in fog, you typically hear the sound of the engine running, which may vary in pitch depending on the speed. Additionally, the boat will likely sound its fog horn at regular intervals, producing a deep, resonant blast to alert nearby vessels of its presence. This combination of engine noise and the fog horn serves as important safety measures in low visibility conditions.
What sound signal indicated a power driven vessel in underway in the fog?
A power driven vessel making way shall sound at intervals of not more than 2 min one prolonged blast. A power driven vessel under way, but stopped & no making way, shall sound at intervals of not more than 2 min two prolonged blas in sucession, at intervals of about 2 sec between them.7 blasts
What sound signal should you hear when a powerboat is underway in the fog?
When a powerboat is underway in fog, it should sound a prolonged blast on the horn at intervals of not more than two minutes. This signal helps alert other vessels to its presence in low visibility conditions. Additionally, the boat may also sound shorter blasts to indicate its maneuvering intentions.
What is the sound signal for a pilot vessel in fog?
In fog, a pilot vessel is required to sound one long blast followed by two short blasts on its whistle at intervals of not more than two minutes. The long blast indicates the vessel's presence, while the two short blasts signal its role as a pilot vessel. This sound signal helps other vessels in the vicinity to identify the pilot vessel's location and intentions in reduced visibility conditions.
