Does anyone know what size spin works on a F28? Deminsions would greatly help. Thanks Bk
Not sure which one that represents…ck for keel/centerboard? And maybe there’s another one?
BOAT I J P E ISP JSP PY EY
FREEDOM 28 WI 30.0 12.0 0.0 0.0 26.8 11.0
FREEDOM 28-2 25.8 8.9 34.3 12.3 25.8 8.9
At any rate, the only one listed with Spinnaker info is the 28-2 with a 25.8’ hoist and 8.9 J measurement, generally that equates to the foot length being 1.8 x the JSP. If you’re using the standard pole the luff length would be .95 x ISP. If you’re using teh gun mount, as with the F21 ad F25, you need to scale the whole thing out because the outer end of the pole is much lower and extends a lot furether so the luff has to be a lot longer (my F25 hoist is 32’ but the luff length is 36’) and th foot length is a small percentage londer than a gunmount pole (~10%). Best bet would be to call Steve Haarstick, he knows it all.
My boat is a 1981 F28 ck centerboard with wishbone booms. Spin would be mounted off the mizz mast as to be able to be considered a stay sail, thats what I’ talking about. Bk
In that case, I’ve got nothing.
I just bought a F 28 83 cat ketch and have no idea how to sail it. I have a flasher and a jib which I was told go in front of the mizzen mast. Is that true. Does one fly them with the main up? do they not get in the way. I have sailed many boats, all had headsails up front, and some with roller furlers. I was told by a stranger to attach the jib sheet to the end of the boom of the mizzen mast. Is that true? The sheet has a hook on the end of it and looks like it may fit on the end of the boom. Or do I put it up front in front of the main…? Help
The cat-ketches do not fly spinakers, but they do fly staysails form the mizzen. On the 33, there are 3 different size staysails, probably the same o n the 28. The larger one usually sheets to the end of the boom. soorry gotta go, will get back with more info shortly, Rick 
I have one or two pictures of staysails set, but you need a really wide angle lens to see them clearly. You can sheet a large staysail via a snatchblock on the end of the mizzen boom when running; it keeps the sail drawing, and it is usually best to drop the mizzen to avoid blanketing the staysail. When on any sort of reach, keep the mizzen set and sheet the stays’l to the toerail right aft.

I don’t have any idea of the dimensions which might suit you boat, and this sail is cut a little too flat for best downwind effect. It is about 30 sq m, (300 sq ft) The original was much fuller aloft, but the sailmaker who did this one had his own ideas about the shape, and it likes the wind more abeam than abaft.
The pictures of the staysails are great, but the tack goes where? You seem to have a dingy on board and I cannot see where the tack goes… thanks John
We are enjoying our 1981 Freedom CK CB WB, Clave, previously owned by Numbknots. Playing with the mizzen, we have just used it on beam reach so far, so just used the deckhouse fitting and the rear toe rail as tack and clew to date. Sail draws well. Numbknots asked size of maximum staysail initially. Not answered directly to date. Clearly more sail can be used than currently has been, the limit as the wind increases probably unstayed mast.
