Last year, I replaced the 22 yr old sails on my 28' S2. Based strictly
on stitching inspection, I think the sails had many more years of use
but I replaced them because I was convinced by other people that
sailing performance would improve. I believe the sailing performance
DID improve but cannot be sure because this si so subjective.

Well, you should be happy that you *think* sailing
performance improved, then.

Seriously, did you know know what your boats pointing angles
were with the old sails? Did you not have a good idea for
what speeds it would attain in given wind conditions &
points of sail? What were you doing all the previous times
you sailed?

... Now I am
skeptical and wonder if sails that are lightly used ( i do not race)
really do become significantly stretched and then do not work well.

Depends on what you mean by "lightly used."

Most resins used in sailcloth (especially pre-1990 or so)
get brittle over time even if the sails sit rolled up on a
shelf. Heat also degrades the cloth. So if the sails were
perfectly rolled & stored, they'd suffer loss of strength &
resiliency. UV is also terrible for sails.

Considering 'light use,' hoisting & furling sails puts a
small amount of wear & tear on the fabric & stitching. Any
time the sail flaps or flogs, that's not good for it either.
Folding the sail breaks down the resin & fibers & weakens
the sail. Dragging the sail across the ground or floor is
terrible for it.... in fact I once saw a man bundle a sail
up in his arms and unintentionally drag a corner of it
across a parking lot. When he went to put it in the back of
his station wagon, several sail panels came apart... the
stitching had been abraded to nothing. I've had my sails
damaged by having stitching catch on dock splinters, it
looked like unraveling a knitted sweater.

Would having the old sails reconditioned by SailCare make them perform
well?

Not really. Their treatment does not restore the strength of
the cloth, and if they don't re-cut the sail then the shape
is not restored. It improves the looks though. And if they
restitch places that need it, like batten pockets, this
might be more cost-effective than taking it to a sail maker.

One method to restore the shape of some sails might be to
detach the bolt rope from the bottom of the luff sleeve. The
bolt rope often shrinks with age and this puckers the sail
into a baggy shape, even if it's not blown out. If the bolt
rope is sewn into a sleeve and the stitched thru to hold it
in place, sever the thru stitching and let the tack slide
down from the end of the bolt rope. You might have to put a
slug on the tack so it will stay in the luff groove.

It is also possible to restore some shape in the sail by
recutting, either at the luff round or one or two
broadseams. If you are geting a sail restitched, ask about this.

Most non-racing sailors are getting shoved around with
crappy sails, and don't know any better. Blown-out sails
affect the boats steering and heeling as well as speed &
pointing.
