My suggestion would be to enroll her in a women only weekend ASA course. Having a bit of confidence in your own ability to work with the wind, water and boat in order to get moving is a huge help in instilling a love of sailing. Knowledge is power after all and self confidence is a wonderful thing to have.
The women only courses are also great because it will allow her to socilaize with other women who are starting off in the sport. You know how we all like to go to the bathroom in groups? Turns out we like to be in groups for lots of things.
