Because depending upon the under water area of the hull, there is huge resistance offered from the water.The water acts as something like a wall to the underwater hull.The hull need to over power this resistance for it to start turning.
Using this water resistance, we can actually move the vessel in any direction we want.Let us say we want to move the ship towards the berth while keeping the heading of the vessel parallel to the berth.For berthing in this situation, one school of thought teaches us to berth in this way.For berthing to port side alongside, head to the berth with an angle of around 20 deg with the berth.
We can also use the rudder cycling when we need to reduce the speed of the ship.Can you think of a situation when we need to turn the ship at its position ?We may need to turn the ship near to the berth when we arrive at the berth from down river direction and we need to berth facing upriver direction.But turning in this situation may not be that tricky as we can use the tugs to turn the vessel.Now consider a situation where you have anchored in a very congested anchorage and you need to pick up the anchor and turn the vessel.In this situation if you have bow thruster fitted, it is easier to turn the vessel. in or toward the middle part of a ship or aircraft; midway between the ends 2. along the central fore-and-aft line of a ship or aircraft 3. This is how it is done.Maintain a low forward speed (say around 3 knots). amidship - located in the middle part of a ship or aircraft. “Torpedo ... los!” Two more torpedoes were fired; one ran erratic; the second hit amidships. Thus ships hull are cleaned and repainted with special coating during dry dock operation. http://pammodels.com/I will write here an extract from the article "Or we can also increase or decrease the resistance force by varying the rudder order (say between 5 deg-15 Deg)". It steadies the sprit and can be used to control the sail's performance during a tack. Aus 2.

We should take these to our advantage.

Then see this image taken during actual berthing of the vessel.By varying the strength of these two forces, we can move the ship in any direction we want.Apart from this, there are number of ways we can use this resistance in our favour.For example, let us say we are waiting for the pilot to board in a busy traffic area with engine stopped.

For example we can reduce the speed if we want to have the resultant more toward abeam. As an interjection amidships is a helm order, normally shortened to midships!, to centre the helm in the line of the keel. The resultant of vessel’s headway and the resistance we created will make the ship move towards the berth.We can adjust these two vectors to move the ship in a direction we want.
