The 5.2/5.5 assembly manual can be seen here
http://www.thebeachcats.c…pictures&g2_itemId=35217
There is a pdf download of the manual there also.
It looks like the shroud adjusters have quite a few holes, maybe 10?
What are you needing to do?

Mine are completly missing, so I was ordering some. On the Salty Dog site the description for the 7-hole ones mention "Nacra". I wonder if the pic above showing a 5.8 is the same for a 5.2?

10 holes on mine too
less holes should be fine as long as your shrouds are standard length
think i use the 4th hole from bottom on my chainplates, meaning they are 6 holes too long -

Nacra used the same adjusters on all models. 10 holes on the shrouds, 10 holes on the forestay. 7 will work on the shrouds no problem.

Another quick question... I thought the forestay was a turnbuckle (mine missing here too). Is it an identical adjuster to the shrouds?

Yes it is also a 10 hole adjuster. At the bottom of the adjuster you will have to interlock the 2 bridal wire forks so you can insert them to one side of the adjuster. When interlocked they will not fit inside. There should also be a SS jib tack fitting that will also attach at the same point but will be on the side facing the mast. Line everything up and put a clevis pin through. Try and use a clevis pin that is close to the exact size that works to eliminate movement of the pin and also use a stiff ring in the clevis pin as well and use rigging tape to tape the ring. -

Gary, go to this site
http://www.nacra.us/
click on the header MANUALS. On the left column click on NACRA MANUALS, & NACRA. Also look along the right hand side, second from the bottom,"PARTS". These will get you PDF files that you can download. The parts manual has the part #s for the older NACRAS & PRINDLE CATS.
I have a 1984 boardless/boomless 5.7, & quite a few of the parts are common with the smaller boats. Near the end of the document is a list of common parts. You should get the NACRA Assembly Manual & the Parts Manual. There are other nuggets to be gleaned from them, such as the size & length of different lines.
You will also find that Murrays uses these same part #s for quite a few things.
If the links don't work for you, PM me & I'll send them to you.
This forum is a ton of help. I have received much good advice from MUMMP, ANDREWSCOTT, WOLF & others as a newbie rebuilding an old cat. I probably could have gotten it done, but why try to reinvent the wheel when others have done most of the experimentation, & refined some things quite slickly.

Gary, here is a picture of my bridle as it came off the boat.
Cable on left is forestay. Cable lower center is jib halyard. One shackle is to attach to head of jib, the other to attach tack of jib to the stay. I think previous owner just attached them together when they stored boat for winter. I'm not sure what the tang with 2 square holes that is bolted to chainplate is for.
Anyone have any ideas?
I also noticed they used a quick connect pin to secure the forestay...that is definitely going to be replaced.

That is pretty much the same as mine. The tang is for a Davis type wind indicator. I actually don't like the way the 2 bridles are attached to the chain plate. I put a bow shackle on the chainplate and one on each bridle wire to attache them together, it's a bit more money but a cleaner setup.
That type of quick connecter is pretty secure, mine came rigged similarly and I ran it that way without any problems. I did switch to a normal pin and ring ding though about half way through the season, and I wouldn't trust it on a roller furling rig.

Look on page 39 of the nacra manual for the proper way to rig this portion. The other part questioned in the photo is for an apparent wind indicator, it allows you to remove the indicator while not sailing.
