This video compares a skeg and rudder to an aircraft wing. The idea of your rudder is that is swings the stern side to side using differential pressure or “lift”. As you increase this differential pressure to turn sharper you also increase drag. At some point, you will start to actually lose turning force as you turn your rudder more, yet continue to generate more drag. Having an understanding of how this works can make you a much better coxswain or bowman (blind boat), and improve your steering abilities. Good Luck!
