When I was 20 I was at a lake for a weekend with friends.  I saw that they had an idle 10- or 12-foot sailboat, and I got interested.  I had never been in a sailboat or even seen one up close before, but I looked it over and easily sailed it alone out onto the lake ...

To continue my little sailing story:

You may have guessed that the wind was with me when I left the dock.  And you might guess that it would be hard for me to get back.

Back before public television in the US was nonstop cartoons and gourmet cooking, it often had useful instructional programs.  It happened that about six years before my sailing opportunity, the public TV station had run a little series on sailing.  I believe it was ten half-hour segments after school for two weeks, and I watched them all with interest.  In the series, they demonstrated how to sail a little boat that was not very different from the one I found in front of me that weekend.

Then being a fair swimmer and  knowing some of the basics of sailing, although lacking experience, I was not too afraid to take the boat out for a little trip. I was able without too much problem to sail back toward the wind and beat it back to the dock, the round trip taking less than an hour.

So, like you, Linda, I was able to get some practical knowledge from a slow video.

Alma: I don't remember that the instructional series I watched taught anything about assembling or disassembling anything!
