Re: [Paddlewise] Skeg vs. rudder (plus maint. question)

The fact is that true marine stainless does corrode (very slightly)  this
has little or no effect on it's strength.  It is advisable to replace a
boats standing rigging every ten years or so.  But, this is because of the
possibility of microscopic cracks in the swaged fittings and possible broken
strands in the stainless cable.
