A friend had a little mishap on his Cal 30. It seems the rudder will rotate 180 degrees with the tiller up, allowing the rudder to contact the prop. Not a good idea when the prop is turning! The meeting broke the strut, chipped the prop, and of course...gouged the rudder.
In any event, the strut and prop turned out to be very pink (don't know age). Picture of the carnage attached. Two shaft zincs are forward of the Strut. The strut is isolated from the Zincs by a Cutlass bearing. Do the zinks protect it at all?
Would he be be better off using a non folding prop with a zink mounted on it?
Could two shaft zincs be too many? Too much zinc?
On my boat, I have a shaft Zink (prop is midships) and a zink mounted on the fiberglass skeg rudder. I replace the shaft Zink every 1.5 years, but have never needed to replace the skeg zink. How much do non-bonded Zinks do?
