After switching over from wheel
to tiller on our full keel
Invicta we found that we had excessive weather helm
on starboard tack. We also found that the key-way on rudder
shaft is offset about 5 degrees counterclockwise when rudder
is positioned straight. While motoring boat "pulls" to starboard and continues to do so after motor
is put into neutral (eliminating prop wash).
We pulled the boat to clean bottom thinking one side may be fouled more then the other. We also verified the key-way (and hence tiller) offset. We also checked rudder with a straight edge and verified it was true and not warped. After cleaning
bottom we still experience excessive starboard weather helm
Starting to think these where problems either from when the boat was built or when the hull
was damaged and repaired on port side in 1978. The key-way offset and weather helm problems both could be masted when boat had wheel steering
Are we missing something? In September we are planning on a year long refit
to prepare boat for full time cruising. However this may be a show stopper for using this boat.
Appreciate any thoughts.
