| The aforementioned article in Professional Boatbuilder (written by Eric W. Sponberg iirc) is a really good source to get an idea about rudder design and engineering. If you want to go simply straightforward I recommend to use the GL Rules and Guidelines which can be found here. Have a look at Part 3 (Special Craft) / Chapter 3 (Yachts and Boats up to 24m) / Section 1 (Hull Structures) for rudder sizing and scantlings. Other Classification Societies may have something similar but GL is what I'm familiar with.
