Thanks Sean.
I am aware of the info you mentioned, but I'm trying a different tack.
I first went to Edson and they quoted me a system similar to what's in the E files.
The driving force behind my considering Wheel steering was to free up what is a spacious cockpit. The Stock tiller sweeps half the cockpit, and makes it considerably less spacious.
Unfortunately, Edsons' (and the E file) fix is still cramping my style.
The solution I am working on is to use a Morse cable system which I will mount on the transom.
Using an 18 inch wheel, I get about an 8:1 mechanical advantage, but with a 10 inch rudder arm, I end up at about 2 or 2.5 to 1 (as a function of the 42 inch existing tiller). I will be adding a wheel autohelm, and that's why I want to reduce steering force.
I am about 60% finished, but sailing keeps getting in the way. I hope to "breadboard" the system to finish engineer it before the boat comes out in the fall.
When I have a working system in place I will share it with EY.c.
If you've heard of anybody who has tried this, or if you could suggest some links, I'd be interested.
Thanks again.
Dave
