Three short blasts means that the ship's engine is working in reverse.
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.
When backing up a boat, it's recommended to sound two short blasts of the horn to signal your intention to reverse. This communicates to others in the vicinity that you are maneuvering backward. Always ensure that you're aware of your surroundings and any other vessels in the area while backing up.
A Fog Horn.
When a boat is leaving the dock, the standard signal is to sound one long blast on the horn. This signal alerts other boats and nearby individuals of the vessel's intention to depart. Additionally, it's important to visually ensure that the path is clear and communicate with crew members to avoid accidents. Following these practices helps maintain safety on the water.
The sound signal that you should hear when a power boat is in the fog is one prolonged blast at intervals of no more than 2 minutes.
