Tethered aeronautics

What do you do on a warm spring evening?  When you have a Styrofoam birthday glider with a three foot wingspan?

And you live on a boat?

If you're Zak over across the dock on s/v Ghost, you have it figured it out.  You tie a fishing line to it!  Then after each water landing (some good, some not so much), you just reel it back in for another flight.  And you get your sister Ellie to hold the fishing pole during the launch.

You might have guessed: Zak's dad is a pilot.
