First time question: I own a 1974 Oday 20.

I'm thinking about a furling system for the headsail. Does anyone have recommendations?
I have the original sail plus a genoa. My guess on the genoa is about 130%

You have to have the luff recut to fit the furler. ... and you need to add the U-resistant fabric to the tailing edge. If the Genoa is also original, it is probably not worth recutting. You will have to buy a new headsail.

Tim, furler systems come in several price ranges and structures. You will need to decide what your pocketbook says about this addition. A common model uses an aluminum foil extrusion that holds your foresail/genoa in place. It uses a 6mm channel to insert the sail. Your sail needs a luff line so that the sail can be inserted into the furler extrusion. I think this is what @rgranger has in mind when he talks about "recutting your sail." If you have the "hank-on" type of fastener for attaching your sail to the forestay, buying a new sail might be less expensive than altering your old sail.
