[Public-list] rigging upgrades

[William Wallace]

316 doesn't have the corrosion resistance of 304; I forget now, but I 
used to have a steel book with the various percentages of nickel, 
chromium, etc. in the different stainless steel ranges...

Some sailors complain that Norseman fittings can be hell to change at 
sea, when the wind is blowing 40 knots and your boat is buffeted about 
by ten foot waves!  Those times, it always seems, are when the rigging 
goes!
