Preventing collision of RMS Titanic with Iceberg


Suppose you are a navigator on duty, keeping a watch on the world's biggest metal ship ever made, the speed of your ship is full ocean passage.
Imagine you see a huge iceberg right ahead of you, what is your natural instinct to avoid collision? Reduce speed, Reverse Engines and put the Helm hard over to Port(Left) or to starboard(Right) right ?
Well thats what exactly the third officer Herbert Pitman who was on watchkeeping that time did.
What if I tell you that it is extremely wrong to do, ship is not a car, maneuverability of a ship is very different from that of a car.
When a ship moves forward there is water flow past the rudder, when the helm is put to port the rudder goes to port, the water coming from forward flows freely from starboard side but finds resistance from port side due to rudder, due to resistance a low pressure zone is created on port bow side as a result the ship's head turns to port, in a nutshell for ship to turn there should be some water flow past the rudder either through the movement of ship or movement of water(From Flooding or ebbing tide), also maneuverability of a ship becomes sluggish if the ship is at slow speed.
So to avoid the collision with iceberg all Herbert Pitman had to do was just alter course to hard starboard or port thats it, Titanic was already at high speed would have altered course in time morover Titanic being a finely streamlined ship would have turned even better.
