Okay, so none of them are any good. We all know that. So back to my original question. Which of them is the best for surf? We have to work with what's available. And we DO need rudders on our boats. So if you have to pick one of these totally inadequate rudder systems, which should it be?

And if the situation is so deplorably bad, why doesn't somebody invent something that works?

And, Bill, I know you are going to say you already invented it. But that doesn't do the rest of us any good if it isn't available on the market as a retrofit item for all of our boats.

P.S. About Dotans. They have the same problem I mentioned in the beginning -- either all up or all down, and no halfway for steerage through surf.
