In Light and mediem air I have too much weather helm as I am always pulling on the helm to keep it straight. I have read that I need to rake my rudders forward, but I don't seem to have the adjustment screws in the rudder castings. Can I reduce mast rake and get the same effect? Are the adjusting screws a mod to newer boats? I've only had it out twice in the last couple of weeks, but it is really tiring to have to pull on the helm all the time.
