converting a furling headsail to a hanked on headsail
 
will this work? or is the cut of the two types of sails too different to work well? thanks

You can use it but your furling sail will be very high cut at the clew and so you lose sail area. Also if the sail was purpose built for furling it may be cut differently, possibly flatter and may have padding along the luff to shape it when it furls.
It is also likely a heavier material than you would normally use on a number 1.

It will work but not as well as a regular cut sail.

Most furling headsails have a foam or rope luff to help them maintain their shape when furled partially. Other than that, there should be any reason why it wouldn't work for you. They make an adapter that allows you to hank on wire-luff, roller-furling sails, which would probably be much cheaper than having a sailmaker modify the sail.

They were written up last year in one of the gear reviews... but I don't remember what they're called.

The first thing you should do is get a quote from a sailmaker as to the cost of adding hanks, and recutting the luff if necessary. I would think you may find the cost of retrofitting to hanks would cover a large part of the purchase of a new sail. Depending on the age and quality of the sail you have, you might be better off buying new.

As to the issues mentioned above, you need to figure out whether the sail was built originally for roller furl, or converted from hanks...if not built for roller furling, the other issues are moot.

I've done this to several lightly used, composite tape-luff racing sails that would have otherwise gone into the bin (some racers chuck them if they have the slightest sag...). I've literally downloaded the foretriangle numbers for my existing boat and approached racers and politely inquired whether they had "any old sails they wanted to get rid of". Most did, and surprisingly, I've scored fresh Dacron sails that were used for half a season and then stowed in favour of Kevlar/Mylar, etc. race sails ten years back.

As I cruise, I don't bother having them recut, as the draft and foot and hoist is usually very close to my existing measurements. Converting them to hanks cost me $135 for a No. 3, $150 for a No. 1 and $250 for a composite mainsail, which did require about a five inch cut, plus some different slugs.

I don't race this boat, so I don't care about the ratings. I only know that I have a significantly better suit of sails for $500 than my previous 20 year old blown-out buggers. You tell me if she's sailing well.

Sounds like you get a very good deal on sail work. You boat looks like a C&C design - Viking? Of course she's sailing well, that's in her blood...

Very sweet. You need to gewt that picture over to Lets see what you got!

I did, and thanks. Yes, that's a C&C design built by Ontario Yachts, hull #32, built over the winter of '73-'74. I know the owners of hulls #52 and #56, both '74s (busy year at Ontario Yachts, I guess). I rebuilt the Atomic 4 in '03 and it runs perfectly. I put on a Gori folding prop in '06 and the difference is notable...the boat just spins up much more quickly now in light airs. We cruise like we're racing...I don't carry water outside of bottles, and instead of ice I carry a Koolatron. The boat's a pleasure to sail in all weathers, and I've got her a "caretaker" owner while we circumnavigate for a few years. Everyone says we'll want to keep the bigger, more appointed boat when we return, but what's good for the open ocean isn't for Lake Ontario...a well-found C&C is, so I'll likely "take her back" and just continue messing about in her.
