When I did some riveting on my old boom. My rigger told me to use Monel pops.

So I used Stainless steel pop rivets and they broke off as soon as I hit a close haul. Clearly that wasn't strong enough to hold. I guess I should have mentioned that I sail in the SF Bay where 20kt winds are standard.

I'm thinking of drilling through the boom and putting a bolt in through the middle and using a boom bail, like CaptKermie recommended. Any suggestions on good ways to do this, things to avoid?

Will I hit anything as I drill through the boom? What's inside there?

Thanks guys

The part poping off makes no sense as 3/16 SS rivets have a 1000# + shear each OR the part does NOT use enough rivets

One big issue is what grip range of rivet you used as to short OR to long would cause problems also

If a dirty bottom slows you down what do you think it does to your boat

If I'd of read this when first posted I would have told you that rivets are a poor choice for a vang mount especially when the are loaded in tension. They work quite well in shear but unless they have back washers they will fail in most tension applications.

They only thing that may be in the boom are the fott and reefing lines. Don't drill through when mounting the bail rather layout and drill from each side. You may be able to take the end cap off to look don the boom also .

Good luck.
