This has intrigued me for a while - There is a theory that Titanic's "watertight" compartments were actually a liability under the circumstances arising from her collision with the iceberg. The theory is, compartmentalizing all the flood water at the bow pulled Titanic down at the head so fast and so much that she essentially pulled herself under. The theory further states that if there had been no compartments closed, and the ship could have flooded more evenly, she could have floated longer, possibly even long enough for most people aboard her to be saved (Carpathia arrived less than two hours after the final sinking). And while I've never read this, I have to wonder if a more even pattern of flooding might have greatly decreased stress on Titanic's hull, preventing some of the horrific deaths and injuries that resulted from changes in angle, the breakup, etc. I'd definitely be up for others who know more about this to share their opinions and knowledge here!
