Three short blasts of a horn indicate that a boat is using stern propulsion and is in the act of backing up.
actually engine-room telegraph use- depending on circumstances- All Back Two Thirds ( ship is going into reverse) or if stationary, All Stop. sometimes transliterated as ( Shut her down) or cha cha cha. It is used in this fashion in the song (Little Darling) which mimics and engine- room telegraph.
It means literally, "change of status" as related to a ship's or boat's motion. For example, when beginning to get underway from a pier, the ship will blast three short blasts when the command is issued to the engine room.

It's a salute upon leaving a port of call. "We're underway!"
"I intend going astern"
A boat is astern propulsion and is in the act of backing up
Three short blasts of a boat's horn typically indicate that the vessel is operating in reverse. This signal is used to communicate the boat's intention to other nearby vessels, ensuring safety and preventing collisions in crowded or narrow waterways. It's part of the sound signaling system established by maritime navigation rules.
three short blast
Three short blasts of a horn on a boat typically indicate that the vessel is operating in reverse. This signal is used to communicate the boat's intentions to other vessels in the vicinity, ensuring safety and preventing collisions. It’s important for all boaters to understand these sound signals as part of navigational rules.
Three short blasts tell other boaters, “I am operating astern propulsion.” For some vessels, this tells other boaters, “I am backing up.”
3 short blasts
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.
Five short horn blasts on a boat typically indicate that the vessel is unsure of the other boat's intentions or that it is in a situation of potential danger. This sound signal is often used to communicate a lack of clarity in navigation or to warn other vessels of a possible collision. It's important for boaters to be aware of these signals to ensure safety on the water.
Three short blasts means that the ship's engine is working in reverse.
Eight short blasts of a boat horn typically indicate that a vessel is operating in a state of danger or distress, signaling to other boats that it requires assistance. This sound pattern is part of the International Regulations for Preventing Collisions at Sea (COLREGs) and serves as a warning to nearby vessels. It is important for mariners to recognize this signal and respond appropriately to ensure safety on the water.
