Free Sailing Videos?

Could someone recommend a basic sailing video for novices? While I’m an experienced sailor, my new wife and partner (75 years of age) has NEVER been on a boat, especially the one we’re planning to buy for inland lake Ohio sailing (27′ Hunter or Catalina). I’d like her to feel comfortable, at the very least, behind the wheel.Thanks for your advice. If I could borrow one, I’d be willing to return it in a few weeks.
