in my mind hind sigght is twenty twenty. To look back it is easy for us to say that he shoul dhave had more lifeboats but back then they had every reason to believe the ship woul dnever need them. The witer tight doors, and also some changes made during the construstion lead to this belief. When the Olympic went out for her sea trials they noticed at top sppeds the ship "breathing" meaning the steel would bow out a little, in seeing this they added more steel to Titanic and that was when the promanode deack was enclosed(they thought by adding more steel the ship would be stronger) so Andrews did take steps to fix any problems he saw.
