Overtaking, Inland
Overtaking on the other vessel's starboard side
I intend to overtake you on your starboard side.
One short blast
Who sounds it
Power-driven vessel intending to overtake another power-driven vessel, in sight.
How it's sounded
Short blast: about 1 second (Rule 32(b)).
A short blast is about 1 second. A prolonged blast is 4 to 6 seconds. Clips use 1 and 5 seconds.
Worth remembering
Inland overtaking signals apply whenever in sight, not only in a narrow channel.
The same sound elsewhere
These use the same pattern, so the rules you’re under and the situation decide what it means.
