Dialogue 4

Master: Do you have any information about the vessel ahead of us?

3^rd Off: Not yet, Sir. The vessel doesn’t answer via VHF. With the help of AIS(Automatic Identification System) we found out her name –it’s a twin screw, diesel powered, motorized tank barge “ Inez” flying the Belgian flag, bound from Antwerp to Calais with a cargo of fuel oil.

Master: Inform the general situation.

3^rd Off: It’s 11.05, we passed Cape Griz Nez at a distance of about four miles.

Kit Michailov: I have just communicated with the overhauling vessel. This is Norwegian motor vessel “Credo”, a bulk carrier out of Lisbon bound for Mongstad, Norway. She is about 2.5 miles astern of us, overtaking us on a course 039º at a speed of 16 knots. “Credo” passed Cape Griz Nez about 10 minutes after us and is on our starboard quarter.

Master: I have estimated the situation. The southbound “Inez” will pass about two-thirds of a mile off down the starboard side. “Credo” is overhauling on the starboard quarter. Switch on an auxiliary whistle on the after mast!

3^rd Off: Yes, Sir. Sir, “Inez” has altered course to starboard.

Master: it’s 11.35. Hard-a-starboard! Half ahead! “Credo” is too close to us – sound 5 short and rapid blasts on the whistle according to COLREG 34(d). What is our course?

3^rd Off: We are on a course 080º.

 

The bow of the “Credo” struck “Eglantine” on her starboard side and while inflicting substantial damage did not penetrate the hull.

Master: Sound general alarm! Send distress message “Collision” via radio telex and telex,and “Mayday” message on VHF Channel 16.
