Yes there is.  A link to the picture 'Rhodes22 Rudder Comparison.jpg’ is part of Bob’s posting, at the very bottom, as usual.

> There were a few years where the IMF mainsail was available; but, the centerboard was the old blade style.  Your boat appears to be one of those.  We would need Stan to say for sure.  But, I think the Diamond Board was introduced to correct the helm balance when the IMF mainsail became so popular.  You may find you need the slight forward tilt of the rudder blade.  I’ve never seen this topic discussed before.

>> I, too, was thinking about that relatively large moment arm of the rudder blade. The resulting leverage would magnify slight changes at the rudder, which, in combination with the relatively flat bottom of the R-22 hull, would make the force applied at the rudder all the more effective (if there were more of a keel, slight changes in the rudder would have much less an overall effect).

I lock the tiller in a central position and ease the daggerboard up to fall off, down to head up. A change of an inch or so in depth is enough to change the heading a few degrees. This works best when sailing anywhere from a tight reach to a hard beat.
