If a boater sounds five short blasts on the horn, it typically signifies that the boater is unsure of the intentions of another vessel, especially in situations where visibility is poor or where navigation is challenging. This signal is a way to communicate caution and to request clarification on the other vessel's actions. It's part of the sound signals outlined in the International Regulations for Preventing Collisions at Sea (COLREGs).

If a boater sounds five short blasts using a horn or whistle, it typically indicates danger or an intention to communicate that they are unsure of another vessel's intentions.

Three short blasts tell other boaters, “I am operating astern propulsion.” For some vessels, this tells other boaters, “I am backing up.”
Don't know what it means, but five short blasts from the hoRN must be a warning of some kind?
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.
