3 short blasts
loud
one prolonged blast
A vessel that is backing up typically uses a series of short blasts on its horn to alert other boats of its intention to maneuver in reverse. This sound signal consists of three short blasts, which indicate that the vessel is preparing to move backward. This is part of the International Regulations for Preventing Collisions at Sea (COLREGs) to ensure safety on the water.

Five short blasts on a horn in boating typically signal a warning or indicate that a vessel is unsure of another vessel's intentions, often in situations of restricted visibility or when navigating in close quarters. It can also mean that a vessel is backing up or has an emergency situation. This sound signal is part of the International Regulations for Preventing Collisions at Sea (COLREGs) and is important for maintaining safety on the water.
In restricted visibility, a power-driven vessel underway is required to sound one prolonged blast every 2 minutes. This signal is meant to indicate the vessel's presence to other nearby vessels in low visibility conditions. The prolonged blast lasts for about 4 to 6 seconds. This sound signal helps enhance safety by alerting others to the vessel's location, allowing for better navigation and collision avoidance.
Keeping his/her vessel and crew out of danger
A pleasure craft operator can moor their vessel to a signal only in cases of emergency or when it is necessary to avoid immediate danger. Otherwise, it is not recommended to moor a vessel to a signal as it may obstruct navigation or pose a safety hazard to other vessels.
A vessel signals its bearing by the position where the signal flag is hoisted on the ship. For example, if the flag is hoisted on the starboard side, it indicates a bearing to the starboard side of the vessel. In this way, signal flags are used to communicate information about a vessel's orientation and position to other ships.
its easy sound signal
An anchor ball is a sphere attached to the vessel of an anchor buoy, used as a signal to state that the vessel is anchored.
