“Having regard to the manoeuvring characteristics of ELEFTHERIA, what is the maximum time needed for her to alter 40° to port under 15° of port helm at 13 knots?”
“0330 Called ELEFTHERIA. I used starboard VHF channel 16 – no response. 0344 (see above) 0345 Courses 266° 0346 Checked radar other ship altered course a little to port. He must alter course to starboard. Again the other vessel has been called, no response. On channel 16 I said alter your course to starboard. No response. I altered my course a little bit more to starboard. I checked my binoculars I could not see the ship. 0355 Call to engine room, visibility reduced a little, I said to engine room to give air for whistle and wait on standby. 0356 Helm on manual: Sadet starboard 10° he made that. Whistle is working. We have one short blast and then after on automatic whistle for poor visibility.”
“We are altering course to starboard”
“Having regard to the manoeuvring data of HAKKI DEVAL, what is the maximum period of time required for HAKKI DEVAL to alter 44° to starboard under 10° of helm at 8 knots?”
“A maximum of 4 minutes but probably only 3-3½ minutes.”
“Assuming that visibility was less than 4 miles, that each vessel had detected the echo of the other at a range of about 8 miles and that the CPA was in the region of 3 cables port to port, was a close quarter’s situation developing?”
“The short answer is yes. Indeed the situation had developed shortly thereafter to the extent that risk of collision existed.”
“Yes: in a well used traffic lane off the Northern Coast of Africa in reduced visibility, she should have reduced to manoeuvring speed (approx. 10 knots). Certainly such a speed should have been achieved by C-15 when the vessels were 5 miles apart and on a collision course.”
“No. In restricted visibility, an alteration to port at that stage was inadvisable. Indeed it was based on a wrong appreciation that the vessels were shaping to pass starboard to starboard. In any event it failed to alter the fact that a close quarters situation was developing. The circumstances required a bold alteration of course to starboard of no less than 30°.” iv) Engine action In the absence of a bold alteration and the continued advance of HAKKI DEVAL with risk of collision, in my judgment vigorous steps to take off way should have been undertaken not later than C-6 when the vessels were 2 miles apart. I have asked the Elder Brethren whether they agree with this assessment and they do. Faults of HAKKI DEVAL i). Speed It is not suggested that HAKKI DEVAL’s speed was unsafe. ii). Lookout Just as with ELEFTHERIA the lookout on HAKKI DEVAL was dismal. The initial sighting of the echo of ELEFTHERIA to the effect that she was fine on the port bow of HAKKI DEVAL was wrong. She was somewhat broader on the starboard bow. More to the point, as with ELEFTHERIA, it is clear that thereafter no effective monitoring of the approach of ELEFTHERIA was undertaken save the observation of her initial alteration to port. iii). Starboard helm This latter observation which I have accepted makes the subsequent alteration of 15° to starboard all the more remarkable. I have asked the Elder Brethren this question: - “Was HAKKI DEVAL’s subsequent alteration of 15° to starboard, having detected the porting by ELEFTHERIA, in accord with good seamanship?”
