Bill, this is a payout winch. The starter motor is for reeling the line
back in after the truck mounted winch gets to the end of the runway.
Check
out the video:

The video is a file type that my media player won't recognize. I've decided
against downloading Real and Quicktime after encountering a lot of security
issues with them.

If the starter motor is only used for retrieving the rope after the glider
releases and the truck provides all the motive power for the launch then a
starter motor is fine. I still say get the glider airspeed and let the
pilot decide how much tension to put on the rope.
