I think Naemanson got it right when he wrote "I think the steering claim has been disproved by the analysis of the ship's rudder. It was too small and the Titanic was too large to allow for rapid course changes. There is a good reason for tugboats". I'm more interested in the second claim, that the ship could have stayed afloat long enough for rescuers to save everyone if Bruce Ismay hadn't ordered it to keep going. Does anyone have anything further on that claim?
