Ya, I will take a close look at that when I get the new boat. My Easy Rider tends to wear rudder cable too, but that is because they go through small holes in the Hull to run exterior to the rudder.
Also I usually never paddle without a rudder unless I am in close to shore and need to maneuver. So, I will look into stainless also when the time comes.
So far I cant find anyone else posting on the internet about the rudder cable problem? I wonder if that is the problem Freya had?
