We have a 1983 C-30 which we bought last year. We have an oe Edson wheel and this year have noticed a distinct "pull" to Port when motoring, but does not seem to be a problem when on a reach under sail. I checked and lubricated the cable noting that there is very marginal slack where it attaches to the steering quadrant. I'd appreciate any suggestions or feedback from anyone who has had similar problems and been able to correct the problem. I note that when I attempt to use the auto helm, it seems to overcompensate steering us all over the harbour...so need to fix problem number one first. (Note that when originally installed, the ST 4000+ Autohelm had no problem maintaining a course).Cheers,Barry
