How the Rudder Actually Moves the Boat, Generates "Lift"

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!

Great video. In flying, the adage is "Make small corrections early, not big corrections late." This help keep the relative wind flowing over the wing and the control surfaces.

That was a great illustration. I really do appreciate how you explained that.

Nice video. Quick question is kick up rudder suppose to be all the way down 90 degree ?

Thanks!

thanks for posting. I have a question. I rebuilt a rudder and I guess the symmetry is off. The boat now pulls to port when over 4.7 knots motoring. The boat is a 41 ft sailboat. the wheel wants to turn counter clockwise and the rudder wants to point with the leading edge pointing to starboard and the trailing edge pointing to port. From this are you able to tell which side of the rudder is too thick? too much foil? I was going to pull the boat and grab a grinder. Also do you know of any methods to check for symmetry? thanks

Another point take your air gun and propel air through the water only on one side the rudder nothing happens. Now turn the rudder slowly to the opposite side, no chnage should be observed. Now turn the rudder back to the water movement side now the boat turns because the water flow is pushing against the rudder moving in the same direction the water is moving. No lift just the force of the water moving the rudder away from the greatest water flow upon it.

B.S.!!!!!! If it's a motorized boat it could make a 360 degree turn never stalling as a plane might do!!!
