For what it is worth guys I fished with these hooks in a 2 day tournament. First day we used a swivel over the hook and noticed the problem when changing rigs out late in the day. Day 2 we used monel - I was afraid the swivels had something to do with the wear and barbs going away but had the same problem again on day 2 with the monel rigs.
Hope y'all figgure it out, it sure had me stumped.
Well, Col David Rifkin USN retired replied to me today, along with a Metallurgist. I will summarize their statements...
Neither believed that galvanic reaction was the initial problem. They felt that "fretting" or the wear caused from the swivel or the monel or copper compromised the plating, then galvanic action occurred.
They also felt that normal corrosion/rust would be more likely then glavanic reaction in the scenarios we are talking about. BUT they siad that it should not be happening in the time frames we are talking about. They also said that normal rust or corrosion happens at a much slower pace than galvanic corrsion.
All this being said, I would like to send Col. Rifkin some samples and get his opinion, which I might do after this weekend. Both he and the metallurgist cannot believe what we are seeing in the time we are seeing it.
Owner's do that a lot, gamakatsu's are not as bad but do also, to avoid that use the 4x strong hooks, they do not have the issue, seems to be with the light wire models from what I have seen so I avoid them.
Thanks for the feedback. I think we, including myself, are a little stumped as too the cause for this barb issue. Several of you are sending me hook and we will take a look at them. As far as the galvanic issues I can't comment since there are so many different variables that come in to play. In meantime while I wait for hooks samples I'd like to point out that we do have a product called Rustop that can be applied to hooks that acts as a scraficial annode. We have captains that use it on their trolling rigs to extend the life of hooks. If any of you would like to test it in your conditions, let me know and I'll send some samples:

Also I heard that some of you may just go to a heavier hook. We have that hook. The SSW Circle is a X strong hook while our new Tournament Mutu is XX strong:

I look forward to getting your hook samples and getting an answer to this barb issue.

Well, I just checked our second experiment after one night. I duplicated the same condition, with a set of Eagle Claw ELF2004 5/0's and had similar results. The monel rig still showed the bigest rust colored cloud in the water, with second being swivel and last being bare hook. Interestingly, though the Eagles had the cloud centered over the loop end, where the Owner's started at the barb and point. So they are still sharp. So, I'm guessing Tony009, might have been on to something when he was talking about the smaller areas can be missed in the coating process, hopefully it was just some recent batches.
Tony, thanks for getting involved in this issue. It's very nice to see a company step and deal with a problem. If we can be any help drop me an email or give a call.
Oh, we do stock the Ruststop product, I 'll give a couple samples to some of customers who have reported problems.
Seems as if the point of the barb fatigues when pushed through the swivel then breaks off but however we had the same thing happen when we used a monel loop then twisted it tight on the bend of the hook.
