Dean:I also need to replace my "Boom to Mast Attachment" on an O'Day 28. I usually think of this as the gooseneck, but any research I've done does not show parts that are remotely close to the odd rig that O'Day cursed us with.A short term solution might be to wrape wire around it to ensure it doesn't release.ALso, I've heard that there is an O'Day parts store in the Fall River MA area (original home of O'Day) that may have it. I'm told it's DNR Enterprises, but I haven't found it on the web yet.If you find a solution, please drop me an email, so I can also replace my parts.Hugh MacKenzie
