When running at cruising speed I thought it was normal for a single screw boat to be more difficult to turn the helm in one direction than the other. When I take may hand off the wheel of my 26' Sisu it stays where I leave it, but it does take more effort to turn the wheel to starboard than to port. I thought it was due to the rotation of the prop.
So I was asking if a wedge should be applied to the upper or lower 1/2 of the rudder to correct the imbalance.
Lacking any feedback from the forum, yesterday we screwed on a 3" x 1/2" wedge, 1/2 the height of the rudder, to the portside trailing edge of the rudder at the bottom. The result was that it not only solved the problem but actually went slightly the other way (a little harder turning to port now) I think if we shorten this wedge a little we are going to be right on.
I hope this helps some other imbalanced soul.
Excellent food for thought...I'd love to get rid of the imbalance I currently experience. With all the knowledge of such matters on this board, it would be nice if others chimed in on their experiences with this topic.
