An immersed area of 0.1 m 2 at 1 m lever length at a boat speed of 2.5 m/s (about 5 knots) and 5° angle of attack already generates a moment of 180 N⋅m, when the oar has a NACA0012 profile. [7] The steering force of the servo oar is transmitted to the main rudder typically involving an arrangement of two lines and four or more rolls to guide ...
The rudder attaches to the skeg and is steered by cables attached to it. In select sweeping boats, typically fours and eights, a coxswain will control the rudder, while in sculling boats and some sweeping boats, especially pairs, the rudder will be controlled with toe-steering.
