My C&C 27 has a mast-step that looks like this:

The previous owner had attached the 4:1 purchase boom vang to the 45 degree
side plate which has resulted in bending the side plate!
It was recommended to me to use a boom/mast bail bolted across the vertical
portion of the mast-step bracket at the aft-most set of holes, with a bolt and
filler ‘tube’ to avoid compressing the mast step bracket. Or to replace the aft
mast-retention pin with the same set-up.
Dimensions of the mast step (‘vertical’ bracket) are:
Outside width = 5 inches
Inside width = 4-1/4 inches
Hole diameter = 7/8 inches
Pin diameter = 5/8 inches
2 problems I am finding:
1) I can’t find a 5-inch wide bail
2) The larger size bails I have found (maybe 4 inch wide is the largest I’ve
seen?) use a smaller bolt than 5/8 inches and no meat to drill out the holes in
them, so there would be a lot of ‘slop’ there.
I’m also concerned that if the boom vang can bend that mast-step side plate,
what’s it going to do to a side-loaded bail and/or the vertical mast-step
bracket?
So ... perhaps a mast tang / hound? (much as I hate drilling holes in the mast
... but multiple holes would spread the load). I have read somewhere that part
of the side of the standard C&C mast section is thicker which helps with this
sort of thing? Can anyone verify? Sorry, didn’t measure the mast width. There’s
also the sail track there that would complicate a tang / hound installation.
By the way, the previous owner also bent the heck out of the through-bolt on
the boom bail. I’ve replaced that with a new SS bolt
Thanks!
