A couple of thoughts regarding "The Iceberg."
First, I wouldn't rely on anyone's memory of specific details regarding the berg's appearance. After all, they only had a few seconds to view the berg on a dark night. The descriptions seem to confirm the fatal berg had points, but I wouldn't form any hard and fast conclusions beyond that.
Something else -- Titanic was not traveling in a straight line during the accident. It was turning to the right at the moment of impact. This wold cause a constant change in the "face" of the berg as seen from the ship.
Assuming the Fatal Berg was photographed, the position of the paint scar may have nothing to do with the attitude of the iceberg at the time of the accident. Bergs are unstable and being hit by an ocean liner would do nothing to improve that situation. The scar might well have been vertical a day or so later, if it was still visible.
Finally, bottom paints are relatively soft as compared to those used on topsides. This is to allow the antifouling chemicals to "leach" out of the paint binder in service. I am not sure of the composition of the paint used on Titanic, which would have been quite different from the materials used today. Topside paint has always been intended primarily as a protection to the steel and secondarily for good looks. I am not surprised that the softer bottom paint left a mark, but the harder topside paint did not.
Special to Paul -- Thanks to Parks Stephenson, I'm chaning my opinion about the ship steaming for Halifax. I still believe that it did make way for up to 20 minutes after the accident...and that Halifax was the destination...but, Parks has me convinced that
Captain Smith had a better motive than the one I postulated in my book. Smith was probably heading north toward the steamer track where he would presumably have had a better chance of finding assistance.
