Hi folks,

I just relaunched my boat after painting the bottom, installing new
zincs and instruments. That was in March of this year. Around the 1st
of July, I scrubbed the bottom in preparation for a race, and noticed
the zinc on the strut was nearly gone, despite only having been in the
water 3 months. Someone tells me this is because I need an isolator.
What is an isolator, and how does it work? Big picture and simple
answers preferred.

thanks,

Luc
