Too cryptic; sorry.
The idea is to attach a mass of a " less noble" metal to the pieces you 
want to protect.  You may want to ground the "zinc" in addition.
In theory, the zinc will sacrifice itself and preferentially corrode 
first.  Salt water is  as much corrosive fun as swimming pool vapors, I'd 
guess.
It is a traditional solution for protecting steel boat hulls.  On the 
really fancy new boats, they are sometimes using pure aluminum  as a 
sacrifice annode(?) instead .
There is also a way to send a small charge through the work that will 
inhibit corrosion and it sounds like your client can afford it....
