I was under the impression (ie., from school in the '70's), that the zincs protected the steel hull from galvanic corrosion. I don't understand how they would actively protect internal systems. Since they are not active they wouldn't contribute to the EMP coupling issue, but I don't understand how they would protect those systems. Obviously I don't know how your ship works, much more modern than anything I've been on.
