My boat also goes through zincs in 100 days +/-. I have a GI installed. How
can I tell if my boat is the problem or if it's neighbors or the marina
(without disconnecting from shore power for 90 days :-) )?

By far the majority of accelerated zinc loss cause is the shore power
connection.
The first step is to install a galvanic isolator.
Defender has them on sale for about $95 at
