Sorry- didn't see the rudder in the other photo. I think Great Lakes waves are too steep for an over stern rudder. It would be out of the water right when you wanted it to be in.

Mike-
I gave that idea some thought as well.
It must depend on hull shape to some extent??
How far forward (and how deep) does an under-hull rudder need to be, to have a big advantage in the 'staying in the water' quality?
Does putting an extra-deep blade on a stern-hung rudder create a lot more drag than an under-hull rudder?

I just couldn't come up with a good retracting design that seemed to be a lot better than a stern-hung rudder.
Probably the best model to follow would be Rune Eurenius' rudder built around a bike pedal bearing...

or some of Bjorn's ideas.
There's less than 6" of depth inside the stern of my 'NoName' - and that's a foot forward of the end of the boat. Not much room for a bearing and retracting arrangement. Smarter heads needed, I guess.. ;-)

It was a tough call- I 'hate' stern-hung rudders with all that metal hardware 'out there' to damage other boats (and swimmers).
But, a non-retracting under-hull rudder is just not practical for anything but a workout boat like a surfski, IMO.

I've said, again and again :"No rudder boats for me!" and here I am, owning two!
