Why do ships honk 2 times?

Ships have long been associated with the sound of honking, and it is not uncommon to hear a ship letting out two short blasts of its horn. This particular sequence of honking serves a specific purpose and has various meanings in the maritime world. So, why do ships honk two times? Let’s explore the reasons behind this common practice.

The primary purpose of a ship’s horn is to communicate with other vessels, signaling their presence, intentions, and any potential dangers. Honking twice is commonly used as a warning signal to let nearby ships or mariners know about a specific maneuver or action the ship is about to perform. For instance, when a ship is about to depart a dock or a berth, it will usually honk twice to alert other vessels in the vicinity that it is preparing to move.

Additionally, ships may also honk twice to signal their presence in foggy or low visibility conditions. This helps other ships, especially those without radar or advanced navigation systems, to be aware of their surroundings and avoid potential collisions. The sound of the ship’s horn can travel over long distances, cutting through the mist and alerting others to the ship’s presence.

Furthermore, two short blasts may also indicate a ship’s intention to pass another vessel. This is often used when overtaking, giving the vessel being passed a clear indication of the ship’s upcoming maneuver. By honking twice, sailors adhere to the International Regulations for Preventing Collisions at Sea (COLREGs), which provide guidelines for safe navigation and collision avoidance.

It’s important to note that ships must comply with specific rules and protocols when using their horns. Every ship is equipped with a set of unique horn signals, and these signals may vary depending on the region, country, or waterway in which the ship operates. Therefore, it is vital for sailors and maritime professionals to be well-versed in the horn signals applicable in their area of operation.
