Full astern or Stop?

A lot of you (Maybe even you) believe that when they spotted the iceberg, the order full astern was given to the engines. However, this is probably not true. First of all, at the time of impact Titanic was at "Full Ahead" If they were to suddenly reverse the engines (Called a crash stop) it would cause a shudder no one could miss. No survivors reported such a violent shudder. Also, about 3-4 people in the engine/boiler room says the order was Stop. Also, reversing the engines doesn't make sense. What if the stern hits an iceberg? Another theory is the order was stop, then reverse. Why bother reversing when you just stopped the engines? Also, wouldn't reversing the engines complicate the order hard a starboard? With this evidence, I can now say this: Murdoch ordered "Hard a starboard" and the engines stopped. Why? He was attempting to steer away from the iceberg and stop the ship, so they don't hit anymore icebergs. What does this mean? No full astern order was given. But hey, this is still a debatable question. But I, and hopefully you, now believe the order Stop was given.
