I've 2x Ezzy Waves got 2nd hand ages ago, rig fine, still looks good.
bullet proof material.
except the top seems to have lost its shape. Appears to just hang open.
I know sail design allows an amount of twist.
rolling (dry) / storing and age etc. Apart from rips'n'tears. When is the end?
Or can the sail (if this over twist is age) be rejuvenated by a sail maker?thanks all

Less downhaul tightens leech.

That issue could be a number of things.

I would try to tighten up the battens, over time the pockets can stretch slightly.

Have you changed masts lately as a lot of masts out there have gone flex top which will make it twist off more.

A sail maker cant do much to a sail thats lost its shape as it will simply cost lots to do it and you would be better off buying a new sail.

Sometimes the sail material will start to break down too so the fibres will soften or the material will start to de-laminte.

The strange-looking head is a design aspect of those Ezzy sails. It looks odd on the beach but should twist open just fine on the water to depower the sail.
If you post pictures however, it would be easier to offer any advice on something that may be wrong.

On the older Ezzy designs that top batten extends out supported to some degree by the rigidity of the heavy material at the luff. Sailworks had a similar planform with the X-T designs but in that case the angle between mast and batten was supported by a rigid piece of plastic which inserted into the mast top. With the Ezzys the sailcloth's rigidity at the top of the setup is responsible for the batten not drooping down toward the clew. My theory is that it's that rigidity which becomes more flexible over time, so that eventually the twist in the leech becomes isolated to that area between the top two battens and there isn't much progressive twist until you're really powered.

I had a similar issue with a 2013ish Cheetah and before I came up with this theory I had my sailmaker take a full 5cm dart in the sail, to shorten the leech and tighten it up so that it would pump better especially when used with a foil. Didn't cost much but didn't do much either, because the sailcloth by the mast is still weakened.

Newer Ezzys seem to have much more progressive twist but perhaps that's just because they haven't started breaking down. It does seem significant that NO other sailmakers are using that unsupported top batten layout.

Thanks basher sails are still functioning fine. Probs just new sail envy when rigging beside new S's.
