- Spade or Balanced Rudder. A spade rudder is basically a rudder plate that is fixed to the rudder stock only at the top of the rudder.
- Unbalanced Rudders. These rudders have their stocks attached at the forward most point of their span.
- a. Semi- Balanced Rudder:
- b. Flaps Rudder:
- c.
What is a tumblehome on a ship?
Tumblehome is a term describing a hull which grows narrower above the waterline than its beam. The opposite of tumblehome is flare. A small amount of tumblehome is normal in many naval architecture designs in order to allow any small projections at deck level to clear wharves.
What is tumblehome in architecture?
A small amount of tumblehome is normal in many naval architecture designs in order to allow any small projections at deck level to clear wharves. The term is also applied to automobile design, where a vehicle’s sides taper inward as they go up.
