I believe greg’s download is for the freedm 2-28 cat not cat ketch.

I have general specs and rigging info for a F28 wishbone centerboard - I’m looking for sail specs for a wrap-around main and mizzen - or a sail maker who has them and is willing to give them up.
Haarstick should have the specs for the wrap around sails, I inquired about new wrap arounds for a F33CK. They will try and talk you out of it and getting new one piece sails and going with a track on your mast. Personally I won’t go that route because I don’t want to drill holes in my masts and looking at the G10 set up I think I’m going to try and go with that. It gives full battans, more roach without adding a track system. I probably won’t be getting new sails for at least another year yet.
Once up, wishbone sails are the best and easiest to handle single-handed. No one ever mentions the great advantage to having a steady banister to hold on to going forward. I’m still surfing to find sail dimensions. So far no luck.
The original wrap around sails were made by ulmer sails, not haarstick. Ulmer sail is now UK sailmakers.
If you are located in the USA you can contact Thurston Quantum sails, Bristol, RI. Last June I had Steve Thurston out for a test sail on Raven. He took some dimensions of my rig and concluded that my sail are cut (Ulmer) to the original specifications. He indicated he and Gary Hoyt sailed a F28 CK in the early 80s and came up with slightly smaller sails that improved the boats handling, clearence in the cockpit and over the deck. He quoted me about $8k for a new main and mizzen. After looking at other rig posabilities and distilling what others have said on this forum I am keeping the wishbones and the wraparound sails. I haven’t ordered new sails yet but I will be some time next year.
The Freedom 30 Cat Ketch is the US Freedom 28. Here is the link to he documents which apply to the TPI Freedom 28 Cat Ketch as well. More variation through the years than across the ocean?

My 1981 Freedom 28 (UK 30) cat ketch is #112
I wondered if the UK builders were assigned starting with #100?
To those of you with Freedom 28 cat ketches or F30 cat ketches in Europe, how about year of production and hull number.
I know the Freedom 30 cat ketch was produced longer in England but curious as to how many and when.
The first Freedom 28 Cat Ketch I went on was #3 built by TPI in 1979.
Instead of the expense of wrap around sails or adding track to the mast, have you considered single-ply sails secured to the mast with Parrel beads? https://en.wikipedia.org/wiki/Parrel_beads
Some time since you asked the question. 
Feronia (ex Saoirse, ex Hourriya) has the HIN FR28 107 5/11/80. As she was built in the UK I assume she was built in November, not May. Although marketed as the FR30, the works hadn’t got around to using “30” - the glassfibre top of the centreboard trunk has “FR28 107” scrawled across it.
