Try to keep her "on her feet" ...
for better sailing performance. It is also makes most people more comfortable to sail in a boat that is heeling no more than 15 degrees. One thing that happens when you heel over excessively is that there may be far less rudder actually in the water, which makes it all that much harder to control the tiller. Stan is right, you might want to make sure you have your rudder fully extended. I suppose that you could experiment with the angle of your centerboard as you reach boat speed. It makes some sense that the center of resistance could be moved back this way to be more in balance with the center of effort in the sails. I am not familiar with how a Cat 22 performs but I would tend to find ways to sail at boat speed with the boat more upright (besides, with the centerboard raked back, you may be making more leeway than you want). This is where I would start with letting the traveler out. This allows you to maintain the basic sail trim, and only adjust the angle of attack.All that weather helm is slow because you have to pull the tiller hard over to counter act the unbalanced helm. The rudder is acting like a huge brake, dragging thru the water at an un-natural angle. If you let the traveler out and maintain good sail trim (with the mainsheet and the vang), your boat will sail more upright, "on her feet", and your rudder will be basically angled in the direction you are traveling, basically straight ahead with far less friction thru the water.I think that many boats perform best at varying angles of heel. With our shoal draft keel and spade rudder, it appears to me that we achieve our best performance at a heeling angle of about 25 degrees. Up to that point, we are relatively comfortable and have managable weather helm. From 25 to 30 degrees, we are balancing between being performance oriented and being overwhelmed (over 30). I am lucky in that my crew likes to sail up to about 20 degrees, then we have to be on our toes too much after we are consistently heeling up to 25 degrees. Up to 15 degrees seems to be the comfort zone for most people, but I find that we are always seeking more performance at that point.Keep in mind that we sail on a lake with very small waves and warm water, so intimidation is not a factor. I have no doubt that if we were in more open water in a colder environment, our comfort zone would be different.
