RMS Titanic Alternative Theories - Pack Ice

Pack Ice

In 2003, Captain L. M. Collins, a former member of the Ice Pilotage Service, published The Sinking of the Titanic: The Mystery Solved proposing, based upon his own experience of ice navigation and witness statements given at the two post-disaster enquiries, that what the Titanic hit was not an iceberg but low-lying pack ice. He based his conclusion upon three main pieces of evidence.

1. At 11:30 pm on the night of the sinking, the two lookouts spotted what they believed to be haze on the horizon, extending approximately 20° on either side of the ship's bow, despite there being no other reports of haze at any time. Collins believes that what they saw was not haze but a strip of pack ice, 3–4 mi (4.8–6.4 km) ahead of the ship.
2. The ice was variously reported as 60 ft (18 m) high by the lookouts, 100 ft (30 m) high by Quartermaster Rowe on the poop deck, and only very low in the water by Fourth Officer Boxhall, on the starboard side near the darkened bridge. Collins believes that this was due to 'an optical phenomenon that is well known to ice navigators' where the flat sea and extreme cold distort the appearance of objects near the waterline, making them appear to be the height of the ship's lights, about 60 ft (18 m) above the surface near the bow, and 100 ft (30 m) high alongside the superstructure.
3. A ship such as the Titanic turned by pivoting about a point approximately a third of the ship's length from the bow, with the result that with her rudder hard over, she could not have avoided crushing her entire starboard side into an iceberg were such a collision to occur, with the result that 'the hull and possibly the superstructure on the starboard side would have been rent. In all probability, the ship would have flooded, capsized, and sunk within minutes.'
