Captain Smith did alter course to pass well South of the known field of Icebergs. however he was unaware that, that year had an unusual amount of Ice shedding and drifting beyond the normal danger area. Had he been making his normal transients and not involved in the Commissioning of the Titanic he may have been aware of it. Captain Smith was also not proceeding at best speed as often reported. In fact he was not using all boilers. As this was a 'Shake Down' Cruise he was alternating use of the boilers so the men could check the ones taken 'Off Line'. Discovery did a very good documentary of little know contributing events, like: The lookouts binoculars were locked away and the Officer who put them there left the ship with the key before sailing. The rude response of the Titanic's Radio Operator, caused the California's Radio Operator to give up on relaying the Ice Danger message to the Titanic. There was also one message regarding the southerly extent of the Icebergs that was not delivered to the Bridge as it had been improperly addressed. From another source I've heard that given the events that brought the Titanic to the moment the Iceberg was sighted; the only action that would have made a difference was, No Action. Had the Titanic not attempted to turn and hit the Iceberg head-on it would have problem only flooded the first or possibly second compartment in which case it could have stayed afloat. The extent of damage that occurred was due to improper metallurgy in some of the rivets that were used. It was failure of these rivets that caused the breach of the hull. The metal did not tear for 300 feet as reported.
