So I just bought a 82 Mac 25 and the owner wasn't there when I acquired it (his son was) and so I couldn't ask questions about rigging and the like. I've never actually set up a mast before until now. So I was able to get the mast up but I was unsure of the line that holds the boom up. It came loose during transit so am I correct that it connects to the same pivot as the rearstay? The rearstay has this funny hook on it that only has about a foot of cable that lets it move so I'm not sure what that is. And then, if anyone has a picture of how the boomvang is connected that would be great because I have no idea how it's supposed to be connected and the owner's manual on macgregor-boats.com is not very helpful in this respect. Any help would be greatly appreciated. Thanks, Zeke

Boom
The cable hanging off the backstay is probably used to hold up the boom when not in use. A better way is to install another line at the mast to use as a topping lift. It can be used as a backup main halyard. Attach topping lift to end of boom, which will be supported between mainsheet and topping lift, (add a bungee to keep from swinging side to side. A boom vang attaches to the base of the mast and the bail on the bottom of the boom.

topping lift
I have a 26d, so this may not be correct for a 25. but sounds like the small cable attached to the long rear cable is the backstay/topping lift. you clip the end of the boom to the short cable (topping lift), when the main sail is not attached. the front end of the boom is attached to the mast, with probalby a pin, or clip. that is the strong critical attachment point. adding a new line from deck to top of mast, to back stay is a good idea, but will undoubtly complicate an already confusing array of lines and blocks... try this site for manuals and more info on you specific boat. macgregor-boats.com best of luck!

boom vang?
Thanks for your help on this. So the boom vang (I assume) is the double block assembly that connects to the bottom of the boom. Here's an excerpt from the manual from macgregor-boats.com Attach the double block to the boom end tang with the small shackle. Run the mainsheet through the swivel cam cleat block, through the forward pulley in the double block on the boom, through the pulley on the starboard rail, back through the aft pulley on the boom, and tie the end to the deck eye just aft of the swivel cam cleat. This really confuses me (first off because I don't know what the half the words mean) but without a picture I don't know what they're trying to describe. Thanks again for any help.

Uh, I think that is...
the main sheet set up...the description refers to the end of the boom...on the 25, that would be main sheet, not boom vang. Here are a couple of pictures of the main sheet set up. For a boom vang set up...go to virtually any site...try Harken for example.

vang
You can have the mainsheet attached to the end of the boom, or mid-boom (acutally 3/4), with a bail on the boom closer to the mast used for a boom vang.

Upside down V
Forget about the boom vang idea right now. That is advanced. The description you have is for the basic boom control system at the stern of this boat. When properly rigged, it will look like an upside down V, and will let the mainsail adjust to the wind, as needed. Good luck! It might be a good idea to find someone who is an experienced sailor who can show you the ropes.
