My 20 front beam has the same deal as the rear beam. Would appear to be an extruded part of the beam.

Hmmmmm. I really thought that was an extra piece but you certainly could be right. Either way, if it looks like the rear beam reinforcement, it will be a lot easier to work around than the infusion-style pieces.

It is like the Prindle, the strip and 2 bolts are one piece, If you can remove the other nut and see if you can force the piece up into the beam, remove and replace. If I recall the bolts were welded to the strip.

So I can't just replace a bolt? Its a strip that goes in there that I have to order from Nacra?

No, that stuff is to be expected (and easily ignored if you're not directly involved). Some poor dog getting "special" attention is definitely new here.

I would bet that it's two loose stainless steel bolts that go through a 1/4" or 3/16" aluminum backing plate inside the beam. I would expect to see enough corrosion on that plate to justify replacing it but you might get lucky and be able to reuse it.

You can get pre-anodized aluminum bar stock from McMaster. You will have the exposed cut end and the holes you drilled where the anodizing will not exist - but I would spray paint the exposed areas and use plenty of 42 or 5200 on reassembly. You should be able to get plenty of what you need for under $20.
McMaster anodized aluminum

McMaster never links easily. From that link, choose Multipurpose 6061 alloy. On the left menu from there, click "anodized". Pick the size you need from there.

I built a new beam awhile back and ordered all the new parts needed. The part was called a "bolt plate" which was made up of SS bar with the SS bolts welded to it. Like Hullflyer said.

What a clusterfu....

So you have to take the beam bolts out, then get the box insert out of there (BFH works the best here) and here's what you get as your consolation prize:

The beam box insert seems to have taken the brunt of the galvanic corrosion.

FWIW, those bolts aren't stainless as they really, REALLY liked my magnet lamp.

I can't imagine why those are magnetic. They should be 316SS. We know Nacra of old (or any manufacturer really) and they wouldn't have put in some exotic expensive hardware where a bigger bolt would do.

Really? Maybe previous owners? Undecided (the boat) does indeed have a colorful history.
