I am wondering if the the piece of equipment I have is correct. It is the where the main sheet connects onto the aft end of the boom (sorry don't know the proper name). There is a bracket at the aft end of the boom (4" by 1") that is held on with a skinny bolt that rotates freely. I can't tell how the bolt is fastened (lock nut?) but it doesn't look very substantial. Is this how it should be? Also when reefing the main sail on the 25, the manual says to tighten up the thumb screw on the mast. Our thumb srew was missing, I need to buy a replacement. Any suggestions on a source for small Macgregor parts like that ? How does it tighten, does it have a nut of some kind on the back? Thanks in advance. Andy

Two part line pully attachment point.
That metal fixture is where the two part line pully attaches to. Also, it seems that there should be a cleat for the rope, rather than having it pulled through the hole with the rather sharp edge. And yes, that is the boom, which connects to the mast. The thumb screw?...you can buy one of those at any hardware store. Get the stainless steel ones, if available.

Mac 22/25 outhaul
This forum moves way too fast for me; I can barely get a pic together before the subject is several hundred posts gone! Anyway, rzxtc, this is how my sailmaker set my outhaul up after seeing the original. The line will still chafe at the clew unless you add a block there.

?? My 25 never had a block. ??
Guess there are variations in everything, including MacGregors. My boom only has a cleat where the block shown in the photo is located.

It seems like Mac did constant changes in the '70s whenever a new idea occured, Doug. This outhaul was something a sailmaker did when I took a mainsail in to be recut.

Thanks for the info, and.........
how about that bolt that holds the bracket? Should it be that small and loose? How about the thumb screw? Does it just push in to the groove in the mast? Thanks again, Andy

The goosenect attachment......
Only if you intend to roll your mainsail around the boom does the bolt attaching the boom to the mast have to be slightly free. All the thumbscrew does is maintain position in the mast's slot to keep the boom from unrolling. If you don't intend to roll the main onto the boom, you can keep that attachment bolt tight. From past experience, if the time came for you to reef the main (like about 20 knots), you'd probably have to have a smaller storm jib installed too. Of course, I've been able to sail in those conditions using only the jib to get back to the launch ramp. Also, check the stainless steel welding on that gooseneck where the boom connects to the mast. Mine was originally cracked and required a better weld for safety.

Tiny bolt
The bolt you asked about was the one holding the mainsheet bracket onto the end of the boom. To be honest, I don't know what is inside the boom holding it on. It would take a lot to shear it, however, and I haven't really worried about it much. Now its undoubtably destined to fail soon!

John, If the bolt fails it is simple to replace. I changed it this spring because the original owner had somehow bent it. You just drill out the three rivets holding the cast aluminum end cap in place and inside there is nylon insert nut on the end of the bolt. After I replaced the bolt, I tapped out the holes in the aluminum end cap and used machine screws instead of rivets. It was an easy half-hour job and now if I ever need to replace the bolt again, I'll just need to back out the three machine screws.
