Usual thorough Isle of Man Report. No help or info from Panama. So everything is from the Scottish Bard side.

Evening of 2006-11-15, the 35,367 dwt Scottish Bard is westbound to Singapore part-loaded with gas-oil, about to enter the westbound TSS. The 7,074 dwt O Princess is eastbound coming out of the TSS in ballast.

At 20:01, O Princess goes alters course 50+ degrees to port from a course of 049 to about 346, Isle of Man has no explanation for this course change. crossing into the westbound lane. The Scottish Bard is a little slow picking up the course change. When they do, they try to contact the other ship several times with no response, checking the AIS to identify the other ship.

The O Princess is clearly the give-way vessel. But in extremis the Scottish Bard goes hard starboard.

The Scottish Bard is a Marpol single hull. We get lucky and the the O Princess hits the Scottish Bard in the 4P water ballast tank. The upper bow hits at just above deck level, probably lifts the Princess a little. Tha middle of the bulb penetrates just at the light waterline. The penetration at the hull proper is probably less that 2 m. No cargo tank is breached.

The fwd motion of the bigger ship, spins the O Princess to port. The bulb comes clear and the two ship's aft quarters hit.

The Isle of Man report is very harsh on the Scottish Bard. Due to problems with the speed log, they were feeding the GPS (SOG) rather than speed thru the water into the ECDIS which resulted in a 1 knot error. The Isle of Man claims the Scottish Bard bridge should not have tried to contact the O Princess on VHF nor attempted to identify her via AIS. They called these moves "distractions". Instead they should have hit the whistle and gone to starboard and astern much earlier.

The CTX believes the IoM's criticism of the Scottish Bard borders on nonsense. Obviously, if a ship is acting strangely, you should try to figure out why. The IoM position on VHF and AIS is standard UK dogma based on 18th century technology. The O Princess was patently in the wrong. The real question is: why did the O Princess behave as she did? Any why did she not respond to the VHF, when she came on immediately after the collision and asked the Scottish Bard "why did you alter so quickly?". It is unlikely the Panamanians will tell us.

The other interesting point is the lack of penetration. The Scottish Bard was at 13.5 knots. The O Princess was originally at 12.5 knots. But she could not have been at anything like this speed and penetrated less than 2 meters into the Bard. It appears almost certain she had reduced speed to something less than 6 knots. Could the port turn have been a loss of steering, at which point she went astern? But if she went astern, it should have turned her bow back to starboard. Without a meaningful Panamanian investigation, we just don't know.
