One short blast of a boats horn can mean a couple of things.
Horns are used to communicate with other boats to avoid collisions.
If you are overtaking a boat from the rear, one short blast will let the other boat know that you are going to pass them on the starboard side, two blasts indicate passing on the port side. The other boat should return your one blast, or two blasts, to let you know that they are aware of you and acknowledge your intentions.
If you are heading straight towards another vessel, one blast will indicate you intentions of passing port to port. If you pass starboard to starboard then two blasts are required. The last situation is if you are going to be crossing in front of another boat. Remember, the boat coming from the right has the right of way. Giving one blast lets the boat to your right know that you see them and are going to give way to them, again all these signals should be acknowledged by the other vessel. If you do not receive a return signal, assume they are either drunk or do not see you. These rules are for inland waters, such as lakes rivers, bays, harbors and the like. Different rules may apply when you are on the high seas.
