what about the bildge pumps? I wouldn't want to cut the Juice to them

mine are on all the time as long as the batteries have juice... (there is a fuse right next to the battery to pull to kill the pumps....)

I would make sure you tie up your dock lines as well

My fountain has more zincs on it than my Sea Ray, the Sea Ray is always in the water. even at a bad marine with electricity in the water, it won't eat up your zincs in a week. i don't think you will need the zinc fish. Tom

I've been burned by electrolysis so I'm corning the market on zincs. I'd get the zinc "grouper", clip it to one of the negines and hang it overboard. THe risk isn't so much your boat but the marina and boats around you.

My marina let a homemeade housboat in with his 12V lines haning in water unedboat. THere was significant dmage in less than 2 weeks.

Old wooden-hull boaters won't moor in a marina without them.

Also make sure you have a galvonic isolator in the 110V shoreline circuit.
