Commercial galvanic isolators have both capacitors AND diodes. Belt and suspenders.

It was a quick and easy project, although the installation under the cockpit was a bit of a challenge.

I recall the breakover voltage as .6 not .7, but the effect is the same. 1.2 or 1.4 volts of breakover from two diodes in series will stop the galvanic current. And for the frugal among us, and I think that covers most all sailors with boats under about 50 feet, the price of a 1000 volt, 50 amp diode at Radio Shack is about $2.99. Add a small project box, some wire, and a couple of stud terminals, and you’ve got a homemade galvanic isolator for about $20-25.
