In fog, a boat typically makes a distinct sound known as a foghorn. This low, loud blast is used to alert other vessels of its presence and navigate safely through reduced visibility. The sound can vary in duration and intensity, often repeating at regular intervals to ensure it can be heard over the dense fog.
A Fog Horn.
The sound signal that you should hear when a power boat is in the fog is one prolonged blast at intervals of no more than 2 minutes.
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.
A boat make bbbbbbbbbbmev sound.
A rapidly ringing bell every minute signals a vessel at anchor.
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.
Fog?
If you hear a fog signal from another boat but cannot see it, you should reduce your speed and maintain a proper lookout. Use radar and other navigation aids to help determine the other vessel's position. Be prepared to take evasive action if necessary, and sound your own fog signal to alert others to your presence. Always stay vigilant and ready to respond to any potential hazards.
What's fog? Fog is caused by the condensation of water molecules in air. This leads to the increase in the density in air. So, the layman answer can be: Velocity of sound is greater in Denser materials, so during fog velocity of sound is greater. Mathematicaly: v2=Bulk modulus/density =stress/strain*density we can say stress due to sound wave normally and in fog is constant. Therefore, v2 is inversely proportional to strain*density. during fog this value is less than normal, that's why velocity of sound wave in fog is greater.
The vowel sound of the OA in "boat" will be a long O (oh)sound, as in coat and float.
