What material is a rudder made of?

What is an emergency rudder?

There are basically two types of emergency rudders:

Stock failure: Most rudders are constructed around
a solid or hollow stainless steel or aluminum stock

traditional bronze stuffing boxes mounted in a vertical position over the boat’s rudder post

What is a rudder shoe?
a tapering or projecting stern section of a vessel’s keel, which protects the propeller and supports the rudder
. FWIK – The “rudder shoe” is stern most end of the skeg and is what the bottom shaft of the rudder fits into for support.
Is a longer rudder better?
As a rule of thumb,
longer, narrower rudders are more efficient than short, wide rudders
, and the aspect ratio describes precisely this relationship. Thus, rudders on high-performance sailing vessels are said to have a high-aspect ratio.
What does a ship rudder look like?
Did the Chinese invent the rudder?
The Rudder
The Chinese developed the device for steering a ship in the First Century A.D.
, according to Chinese technology historian Yongxiang Lu. The rudder enabled ships to steer without using oars, making it a lot easier to navigate. According to Temple’s book.

An emergency tiller
fits to the top of the rudder stock, normally just behind the helmsman’s position at the wheel
. Space is limited so the tiller is stubby and almost impossible to steer by muscle alone. A rope purchase to the aft winches or the aft cleats is the usual solution.
How is rudder attached?
Outboard rudders are hung on the stern or transom. Inboard rudders are hung from a keel or skeg and are thus fully submerged beneath the hull,
connected to the steering mechanism by a rudder post that comes up through the hull to deck level, often into a cockpit
.
Why rudder is hollow?
Rudders are hollow and so
provide for some buoyancy
. In order to minimise the risk of corrosion internal surfaces are provided with a protective coating and some are even filled with foam.
How do steering system effects the rudder?

generates a torsional force at a certain scale which is then, in turn, is transmitted to the rudder stock that turns the rudder
