The
photo above shows Emma at the helm of the Warrior. In spite of her
revolutionary design, in service the ship was very hard to steer and
erratic to maneuver. There are facilities for up to 24 men to steer at
once using linked wheels on three decks. One reason for this is that she
did not have a balanced rudder. A balanced rudder has up to a quarter of the
rudder blade extending forward of the rudder post, and it greatly
reduces the effort required to steer powered ships that have a propeller
directly in front of the rudder. The etching on the left shows the stern of Warrior under construction at Thames Ironworks. The two-bladed propeller was located in front of the rudder post and could be retracted up into the hull when the ship was under sail.
In the evening D and Sarah joined us to see something of Portsmouth after dark.
