Bartek,
Most winches have more than one drum. In Europe, one winch can have up
to 8 separate drums and lines. This enables a launch every 3 minutes
or less.

I've watched them launch gliders at Lasham at that rate using a single
drum of a Tost winch and a retrieve winch. There is a price to be paid,
of course, maybe 200 feet less altitude (if that much), but a retrieve
winch is somewhat less expensive than upgrading to an 8 drum Hydrostart...
