I am trying to get the proper mast rake in order to steer correctly. But, I'm getting goofy results from my efforts to try different mast rake angles, sail on a beat, and evaluate the helm.
I started with the mast at 3.5 degrees and had bad lee helm in light air. Moved the rake to 5.5 degrees and had very bad lee helm in light air. Then I moved the rake to 8.5 degrees and had very bad lee helm, until the wind increased from under 5kn to 12-15kn and I had a reasonable amount (a hair too much) of weather helm. The wind continued to fluctuate from light to 15kn and the steering continued to fluctuate from lee to weather helm. I tried raising the cb 25% but didn't notice any variance in steering.
I don't remember any keel boats acting like this, is it a centerboarder thing?
