Mb = 0.483m x 2,572 N = 1,242Nm. The torque on the rudder (Mt) was calculated by multiplying the lateral force by the separation between the shaft axis and the centre of pressure. For my rudder it worked out to be 2,572 x (0.41 x 0.33-0.10) = 91Nm; roughly 10kg.

Rudders Thickness Planform Centerboards Thickness Gybing heads Common Subjects Terminology angle of attack - the angle the foil faces to the flow of water over it (this varies on rudders as you steer the boat). aspect ratio - the comparison of the length to the width of the planform of your rudder or centerboard.

Displacement Hull Inboard Rudders Rudder design and steering systems are a big deal nowadays but actually, are nothing new. Really, once design went from the steering oar off the stern quarter to an actual rudder attached to the back, there wasn't much more to do!
Rudder Awareness Sail Magazine
Keel-mounted rudders are attached to the boat's keel, which is the central structural element that runs along the bottom of the hull. Spade rudders are free-standing rudders that are not attached to any part of the boat and are commonly used in racing sailboats. The type of rudder used depends on the boat's size, design, and intended use.

A rudder is an ancient piece of technology that people still use to steer sailboats today. Modern sailboats use many different types of rudders. If you turn the rudder to the left, the stern will turn right, and vice versa. You can use either a steering wheel or a tiller to move the rudder.

This is rudder for the Catamaran and Dinghy for sailing.
The discussed design choices are rudder working conditions (Reynolds numbers and angles of attack), profiles (sectional shapes), properties (area, thickness, span, chord, and rudder aspect ratios), types (the position of the stock and the structural rudder-hull connection), and interactions (among the hull, the propeller, and the rudder).

If the rudder is too small, however, you'll end up with insufficient steering control. Somehow, a happy medium has to be found. The basic rule-of-thumb rudder area formulas are as follows: Average Planing Boat Rudder Area=0.018× . waterline length×draft (hull only) Displacement Boat Rudder Area=0.03 to . 0.04×waterline length×draft

Another term frequently used when discussing rudder design, particularly for sailing vessels, is aspect ratio —simply the square of the rudder's span divided by the rudder's area. As a rule of thumb, longer, narrower rudders are more efficient than short, wide rudders, and the aspect ratio describes precisely this relationship.
