Although I fancy the yawl rig, I can understand people’s reluctance to tearing down a fully operational rig, with masts and all. In case one has a good original rig and just wants to improve the performance of it to windward, and do away with some sheet tangles and reefing issues, here I have come up with two new sails for the existing rig.
I would give the foresail 10% camber and the mainsail 8%. The wider gap between the two sails may be enough to have central sheeting on the foresail, I don’t know.
Anyway, it could be an idea to increase the balance in both sails a bit at boom level. This will let the sails be canted aft a little bit, which is the best vaccination against sheet tangle.
I would do away with the euphroe (spells?) sort of sheet and rather pick one from PJR or from Junk Rig for Beginners.
Have a look.

PS:For those of you who are new to the JR and this group, I can tell you that I have made the sails and sailed with four boats with variations of this rig, based on the originally flat Hasler-McLeod sail.
These sails, with camber, are now well established and fully operational:
- They are fairly easy to make, with several panels being identical.
- They perform well to windward, with their baggy panels (since 1994).
- When set with the luff and leech vertical or even tilted a tiny bit aft, they are very resistant against sheet tangle.
- They reef without problems, and perform and behave well when reefed. The Johanna-sheeting, shown in 'Junk Rig For Beginners' is helpful in controlling the twist when reefed.
- The fanned 3-panel top section is effective to windward. I have tested my two last boats with only three panels set, and we go to windward really well. The two last boats have even proven to tack and sail to windward with only two panels set, but with quite wide tacking angles. Not every boat will do that - Frøken Sørensen and my present Ingeborg are really good.
