Yea, I agree with that. Forces are big on a spade, and in fact my current boat has a skeg hung rudder...although given the limited offshore we do, the primary advantage is catching a few less lobstah traps
BTW/any idea how to inspect for crevice corrosion on a shaft hidden in a bearing without dropping the rudder?
