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
When visibility is very limited, such as in heavy fog, boaters must give an audible signal to others in the area. For a sailboat the signal is one prolonged blast plus two short blasts every two minutes.

The sound signals that it is a sailing vessel underway when you hear one prolonged blast plus two short blasts every two minutes.
One prolonged blast plus two short blasts every two minutes
One prolonged blast followed by one short blast signals to a river lock attendant that a vessel is requesting to enter the lock. This sound pattern is a standard communication method used in maritime navigation to convey a specific intention. The prolonged blast indicates the vessel's approach, while the short blast serves to confirm the request for lock entry.
One prolonged blast followed by one short blast typically signals to the River lock attendant that a vessel is requesting to enter the lock. The prolonged blast indicates the vessel's intention, while the short blast serves as a confirmation or follow-up to the request. This signaling protocol helps ensure safe and efficient navigation through the lock system.
The sound signals that it is a sailing vessel underway when you hear one prolonged blast plus two short blasts every two minutes.
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.
During periods of restricted visibility, vessels must emit one prolonged blast followed by two short blasts every two minutes to signal their presence and intentions to other nearby vessels. This sound signal helps ensure safety and awareness in conditions where visual communication is limited. The prolonged blast alerts other vessels of the ship's position, while the two short blasts indicate that the vessel is underway. These signals are part of the International Regulations for Preventing Collisions at Sea (COLREGs).
One prolonged blast plus two short blasts every two minutes. Explanation: 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 plus two short blasts at intervals of not more than two minutes is the signal used by sailing vessels.
