Re: Mast/Boom Rigging Hardware and Rivets

["Robert Harper" <rharper@xxxxxxxxxxxx>]

You want to use SS rivets for all fittings. Aluminum will turn to powder  
so fast it will make your head spin. In the salty water I sail in, I've  
had aluminum rivets fail in less than six months.

One thing I've heard of for insulating the rivets is to push them through  
electrical tape so that the tape provides a barior between the two metals.  
There is also some good discussion about this on Sailing Anarchy

I hope that helps.
