When two boats approach each other, they use horn blasts to signal the other about their intentions when it comes to moving to avoid collision. 5 short blasts indicates that the signaling boat is unsure about what the other boat is doing.
5 short blasts is a signal warning of imminent danger (or disagreement).
5 (or more) short blasts is the boating DANGER signal. It is mainly used when two vessels are approaching each other and the intent of the other vessel is unknown and/or may be dangerous to either vessel. A prudent captain will immediately slow down or stop when upon hearing this signal and take appropriate action.

1 blast means, I am turning to starboard (right) 2 blasts means, I am turning to port (left) 3 blasts means, I am going astern (backwards) 5 blasts means, I don't know what you are doing, get out of my way.....and usually accompanied by colourful language and waving of arms etc. Often heard around the commercial jetty when recreational boats get in the way of large commercial ferries etc...
Usually the tug towing the barge will sound it's horn or whistle. Most barges are unmanned. 5 or more short blasts of the ships whistle is the danger signal. If you hear this while boating you are likely in the way or crossing the path of the tug and tow, and there is risk of collision. Tugs with tows are much less maneuverable than a small boat and usually must stay in the dredged navigation channel.
