For Option 3:
Could use a RivNut, which may increase the load bearing on the thin
walled boom.

These are commonly available at hardware stores.
You don't need the special tool, you can install them with 2 wrenches.
I'm not sure what the load capabilities
are on these. I used them to install my Vang, but my bolts go in
horizontally through the boom, so most of the
load is on the boom material not pulling out the threading....and of
course, I'm a lot smaller boat.

Good luck!!

My options are: 1) move the vang fitting and drill/tap new holes; 2)
drill/tap the existing holes with larger bolts (which may be too large to fit
in the vang fitting); or 3) install helicoil inserts in the existing holes
(which I've never used before). Thoughts?
