Twin rudders are not parallel to the boat's centerline !!!!
Looking from aft , they are watching about 3-5 degrees inboard. That has nothing to do with the Ackermann-effect . Sailing upwind the leerudder is angled about 5 degrees ( wheather helm). The windward rudder, more or less parallel to the waterline , MUST have 0 degrees then, otherwise it would generate horizontal lift, heeling the boat much more. Anon, non attributable unfortunately, checked salient facts appears accurate. ------------- Robert |

| I was crewing in a catamaran, and the owners way of “tuning”, while sailing, was to disconnect the adjustable crossbar linking the tillers. Then adjusting the length so that the crossbar could just drop on. |
