If a sail is listed as Mylar/Kevlar is it a composite of both

Mylar is the base the other materials are built on.

Can a sail of that type be converted from hank on to roller furling?
Is it a cost effective conversion?

Yes. You might have to shorten the sail. Usually this
is done at the top. Any sail maker can sew on a luff
tape. How well would it hold up? You would need some
sun protection. I'd think it would not be a problem to
roll up a sail. Folding is what you want to avoid.

If you trash the sail, you can always get a new dacron
sail. You would be happier with that than a fancy
sail that is meant for racing. Another option might be
to sell the sail and buy a Dacron sail right off the bat.
