I never suggested the use of any form of grease with zincs. (not at all recommended)
In "another thread" I was mentioning the use of an "electrically conductive" grease, (NOT dielectric), when installing my most important cables
, like the battery
grounds. As you point out, "electrically conductive" is the opposite of dielectric, which means electrically NON-conductive.
The electrically "conductive" grease that I use, is both to fill the voids where air and moisture could cause corrosion
, AND with the fine copper powder that it is loaded with, it increases conductivity a bit at the cable and battery
lug's contact points. It is also very useful on really low amp contact points, like a small dab on LED light bulb contacts... They need the best connection possible.
The stuff is:
Jet-Lube SS-30 Out of Houston Texas
It is sold in small 1/2 pound jars with an applicator brush. It leaves a nasty stain on clothing
, so if it is out where you can brush against the excess, I suggest that you clean the excess with mineral spirits.
I board with our 6' boarding ladder that is folded in half, hinged at the top, and always ready to deploy. When sailing, like the photo
, It is held up with a break away plastic hook, as a fuse. If I fell in and can get to the ladder, I could reach up and grab it, the hook would break, and the ladder come down. Good point though!
Yes, Here in NC, it is too cold for me to be getting in the water
, even with my thin wet suite. Maybe in 6 weeks... Most marinas
have divers that come and scrub boat bottoms periodically. (less so in winter) IF you could time it when the guy was going to be in the water
anyway, he might only charge $20 to change the zinc. (He will have a good drysuite).
If none of this works, do the dangle over the side thing that you originally mentioned. It can't hurt, might work, and you are only talking a couple of months while waiting for the water to warm up. If your marina slip is electrically neutral, you should be OK for that length of time.
As mentioned elsewhere, ALL boats should have a Galvanic Isolator
, so the green wire doesn't connect you to every boat in the marina!
