Rule 34(c)(i) · Maneuvering & warning
Overtake on your starboard side (International)
Two prolonged + one short: “I intend to overtake you on your starboard side” — narrow channel, International Rules.
You hear: 2 prolonged blasts, then 1 short blast.
Meaning
“I intend to overtake you on your starboard side.” Sounded in a narrow channel or fairway when overtaking can take place only if the vessel ahead moves over (Rule 9(e)(i)). The vessel ahead answers with the agreement signal if she consents, or the danger signal if in doubt.
Inland Rules use a different overtaking proposal: one short blast for “I intend to overtake you on your starboard side” — see the Inland overtaking signals.
