Runaway ship
Vessel operators can alert the lock attendant of their request to transit through the lock by sounding one prolonged blast followed by one short blast
Three short blasts means you are operating in reverse. One prolonged blast followed by 3 short blasts means boat under tow in redcued visibility conditions.
One prolonged blast followed by two short blasts every two minutes is a sound signal used by vessels in fog or low visibility conditions. This signal indicates that the boat is under way and making way through the water. It serves to alert other vessels in the area of its presence and movement to help prevent collisions.

One prolonged blast emitted by boat A typically signals its presence and intention to maneuver, often indicating that it is leaving a dock or making a turn. This sound is part of the International Regulations for Preventing Collisions at Sea (COLREGs) and helps communicate the boat's actions to other vessels in the vicinity. The prolonged blast is intended to alert nearby boats and ensure safe navigation.
One long blast of sound announces a boat's presence to other boats.
Horn signals for maneuvering a boat typically include short blasts and prolonged blasts to communicate intentions. One short blast indicates the intention to alter course to starboard, while two short blasts signal a course change to port. A prolonged blast is used to indicate intentions in reduced visibility or to signal danger. It's essential for boaters to understand and use these signals to ensure safe navigation and avoid collisions.
A common signal sound to pass another boater is one prolonged blast followed by two short blasts on a horn or whistle. This signal indicates that you intend to pass on the other boat's starboard side. Make sure to maintain a safe distance and communicate your intentions clearly to avoid collisions.
one prolonged blast
One prolonged blast emitted by boat A using a horn typically signals its presence and intent to maneuver in restricted visibility conditions. This sound signal warns other vessels of the boat's location and helps prevent collisions. It is a standard communication method outlined in the International Regulations for Preventing Collisions at Sea (COLREGs). The prolonged blast is often used to indicate that the vessel is underway and may be approaching a bend or other hazard.
"I am about to turn to starboard".
In foggy conditions, a blast refers to a sound signal made by a boat's horn or whistle to alert other vessels of its presence. This is crucial for safety, as visibility is limited, and the sound helps prevent collisions. The International Regulations for Preventing Collisions at Sea (COLREGs) specify the duration and frequency of these blasts to communicate a vessel's position and intentions effectively. Typically, a prolonged blast lasts about four to six seconds and is repeated at regular intervals.
