The facts I see in evidence are there are thousands and thousands of 30+ year old sailboats on the Chesapeake that have had no issues using zinc anodes.

@Faster, cheaper they may be, but I know it would take time and effort for me to find them and I'd most likely have to pay shipping to get them, so being that I have no problems "doing it the way they've always done it" I guess I'll keep doing it, and not look for a better mousetrap.

Finally, I agree with Chef, that if I saw evidence of stray current (or was just worried about it) at my marina, I'd invest in a galvanic isolator, especially if I planned to keep my boat plugged in.
You know I ran down to the yard and double checked, you're right! The C320 dose not have an outdrive, and I checked twice! It does have a galvonic isolator though. Like I stated before, I ran across this issue when going to buy ZINCS and looked into it. I thought it a good point to bring up here. I'm going with the aluminum anodes and will monitor it closely, as far as what everyone else does they can use Play-Doe if it makes them happy.
I can understand the commitment to zinc, most of us have used it our entire boating history and it has been used for centuries by countless seamen but the aluminum anode is not pure aluminum which would be useless as an anode, the aluminum anode due to the way its manufactured is actually less noble than a zinc anode.

Here is an interesting article that sums up a lot of different articles on the subject.

You don't appear to embrace my analogies but here is another...This reminds me of when synthetic motor oil was really getting popular in the early '90s, I had just bought my Harley in '93 and after 5,000 miles I went to synthetic, many people told me that it was a bad idea because synthetic was TOO slippery! Even HD itself advised against it...until they started selling it. I bought that Harley new, picked it up 20 years ago on April 1st 1993 (Wow time flies) she's in the garage waiting to go out right now, but I need to go and get the boat ready for the season.


You seem pretty passionate about using zinc and thats fine, we all do our own thing!
