Stock failure: Most rudders are constructed around a solid or hollow stainless steel or aluminum stock. This tube or bar connects the rudder to the boat's steering mechanism. In the case of a spade rudder, it also attaches the rudder to the boat. Stocks can fail in several ways, all related to inadequate strength.
And the lift generated (rudder force) is proportional to the velocity of water falling on it. So if a rudder is placed at the aft of the propeller, the increased velocity of the propeller outflow results in a greater lift force. It is only for this reason that a rudder is placed aft of the propeller.

Without the rudder the aircraft can still be controlled using ailerons. The tail-plane helps provide stability and the elevator controls the 'pitch' of the aircraft (up and down). Without these the aircraft cannot be controlled. ... This shows that it is possible to land an aircraft without the normal flight controls.
The rudder keeps the plane straight
In modern multi-engined aircraft where the engines are positioned on the wings, the rudder can be used to compensate for the yaw effect of having one engine not producing enough thrust or in the event of an engine failure.
