Attached is the table of offsets for the team doing my fiberglass work in Ensenada Mexico (Niza Marine - good folks). I forget where I found the factors to make these calculations for my rudder, but this is what is being built. Note, there is a horizontal plate on the top and bottom to direct flow.

Originally, I inquired into articulating rudders as I know at least a couple Willards have one. One knowledgeable/experienced owner of not one but two Willards (one in SE Alaska, the other in Sea of Cortez) said "Pete, have you thought about a fishtail rudder?" So I did a bit of research and found several credible references similar to quote above from Klee Wyck. Relatively inexpensive modification. I own a slip and this will hopefully solve my fear of a particularly difficult configuration.

Fingers crossed - will update when complete!
