The real reason for the Titanic tragedy was not enough rudder for that size ship. I don’t believe any regulations addressed that issue.
One of the key witnesses who worked for the White Star Line tried to get off the rescue vessel dressed as a woman when it entered New York harbor. The caught him anyway and hauled him before the hearings as they did with several others who didn't try to evade congress.
It was a joint committee, hearings begin within a month of the sinking while witness accounts were still fresh. Excellent, probing, fact finding questions and little political grandstanding. It will put our later versions of congress to shame.
Anyone reading those accounts will come out knowing just about all the facts related to the sinking, but an appreciation with the high standards we used to have for people elected to congress.
no bow thrusters, 360 degree stern propulsor pods, roll-stabilizers, radar, sat internet and television, glass wipers on bridge windows, etc.
these were contributory factors also.
The lookouts in the crows’ nest had no binoculars even though there were binoculars on board which no one could locate. When they spotted the iceberg it was already too late to avoid.
What if Titanic had held steady and smashed into the iceberg head on?
Was the rudder problem later addressed on Olympic and Britannic, Titanic’s sister ships?
Running at close to full speed into an iceberg field on a moonless night didn’t help matters.
