No, and I suspect that what you have is an aftermarket addition as was suggested by another poster. One thing about a deck stepped mast is that the force of all those stays and shrouds makes the mast step a convenient and well fixed strong point for securing blocks. The brackets on your boat may have been inspired by the attachment points sometimes provided on boats with keel stepped masts.

From: Steve Thomas Sent: Saturday, July 20, 2013 7:21 AM To: cnc-list@cnc-list.com Subject: Re: Stus-List Boom Vang for C&C 27 Mk III You don't need to use a bail. Just hook the vang shackle to the stainless steel pin in the U channel that confines the mast. That's the way my boat was when I got it 12 years ago. Seems to be original and it has the advantage of being a bit more centred on the mast than your current set-up. It is still working fine as is and the pin hasn't bent. Someday I am going to install a second pin in the rear most set of holes, but I still haven't gotten around to it. My guess is that the PO of your boat had an unintended jibe when there was a pretty good breeze blowing.

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! -------------------------------------------------------------------------------- _______________________________________________ This List is provided by the C&C Photo Album http://www.cncphotoalbum.com CnC-List@cnc-list.com
