Backwinding the jib- learn it, live it, love it!

Besides the drag issue you mention, another reason that rudder modifications shouldn't be made without *very* careful consideration is that even small changes in rudder area can cause the hull's center of lateral resistance to move forward or aft...increasing the rudder area enough will do the latter, which will gradually introduce lee helm (or maybe not so gradually). Not only will this defeat the purpose of trying to make the boat easier to tack, lee helm can be dangerous.

Messing with your rudder design is kind of like messing with the fork angle on a motorcycle...it can be done and serve a purpose, but it isn't something to do unless you *really* know what you are doing, because even very small adjustments can have a major impact on your steering, and not necessarily the one you were going for.
