Five or more short blasts from a boat typically signal danger or uncertainty about another vessel's intentions, particularly in situations where visibility is poor. This sound signal is used to communicate to nearby boats that the operator is unsure of their course and wants to alert them to the potential for collision. It is part of the sound signal regulations outlined in the International Regulations for Preventing Collisions at Sea (COLREGs).

5 short blasts is a signal warning of imminent danger (or disagreement).
Five short horn blasts from another boat on the water usually means danger. It could mean they have doubt in the message they had received from you, whether they did not hear it or did not understand.

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.
Passing on your right side.Signals are (number of blasts):1. Passing you on your left (port) side2. Passing you on your right (starboard) side3. I am moving backwards (astern)4. Danger, don't do that (answer to the other three if dangerous)One short blast means 'I am changing course to starboard.'Two short blasts mean 'I am changing course to port.'Three short blasts mean 'I am operating astern.'Two prolonged blasts followed by one short blast to mean 'I intend to overtake you on your starboard side';Two prolonged blasts followed by two short blasts to mean 'I intend to over-take you on your port side.'A long blast every two minutes is used when operating in fog.
Two short blasts of a horn from a boat typically indicate that the vessel is operating in reverse. This sound signal is part of the International Regulations for Preventing Collisions at Sea (COLREGs) and is used to communicate intentions to other vessels in the vicinity, helping to avoid potential collisions.
Three short blasts of a boat horn typically indicate that the vessel is operating in reverse. This signal is used to communicate to other vessels in the vicinity that the boat is maneuvering backward, helping to ensure safety and prevent collisions. It's part of the International Regulations for Preventing Collisions at Sea (COLREGS) that govern maritime signaling.
