Goose neck separated!

The goose neck on my boom came apart yesterday. The good news is that it happened just as I was heading up wind, shaking out a reef! What would have happened under load? I assume, given the size of the bolts, there is not a lot of pressure at the foot? Anyway, the bolt doesn't appear to be broken to me (though, the end is not completely smooth). Looks like the nut simply came off. Thoughts? I'm going to pull it apart and see whats in the boom, but just wanted to get input first. Pictures are of the mast end of the boom and the goose neck.

Sure looks that way to me too. If so, consider using a locknut in conjunction with the one that was on there.

How is the access to the end plate on the boom?

I agree, it doesn't look as though the bolt broke from the thread pattern at the end. I suspect that the nut worked off the end of the bolt with the twisting of the boom. I must admit that I am not familiar with that particular boom, though if you mentioned the name and size it is likely that someone on this site has worked with it before. Good luck with the repair - hopefully it is not going to be too difficult.

Well, it looks like not only one nut came off the bolt, but two nuts with a lock washer and fender washer! Must have been pretty loose for a while. Lesson learned! I wonder if the corrosion on the inside of the cap can be fixed? If not, maybe some JB Weld.

That appears to be an old roller reefing style boom. There should also have been a strong spring inside your boom that held the cast male square inside of the square socket cast into the aluminum.

Also in terms of the order with which the parts would have assembled there would have been a spring against the aluminum, then the fender washer, then the first nut, then the lock washer and then the second nut.

In order to reef, the way these booms were made to work, you pulled the boom aft away from the mast, disengaging the the cast male square from the square socket. Then you wrapped the mainsail around the boom, and then let the the cast male square engage the socket holding in the reef.

It was a pretty poor solution in many ways so many, if not most boats of this era have upgraded by replacing their roller reefing with slab reefing.

Try brushing some threadlock on the bolt before reassembly.

I'll at least do that, if not drill a hole for a cotter pin in the new bolt. First, I have to fill the valley created by electrolysis where the washer will sit. It always amazes me how random the electrolysis appears to be. It attacked one quarter of the piece and left the rest fully intact. The light is pretty intense in th picture, so it's hard to see, but the lower section has about a 1/2" eaten away. I wonder is painting the washer with "liquid electrical tape" would eliminate the electrolysis? I thought about investigating if I could replace the cap altogether, but I think Jeff's interesting post about possibly having been a roller furler boom answered that! A relic to say the least.
