Robert,
Winching is much more common overseas than here in Oz, and they regularly
send fully ballasted open class gliders up on the wire. As with aerotowing
using motorgliders, it is mostly the initial ground run that is slower than
normal. Once the glider is in the air the difference in weights is less
obvious.
The sight of an ASH25 on the wire is impressive. I think the last time I saw
this was in Leeton at the junior nats, and the '25 was Bernard's.
BTW it was Anita and I who bought the auto towing system from Greg. It will
see some use here at Kentucky getting the '19 in the air.

No doubt in my mind that eventually this system coupled to a dual winch

the glider end is the way to go, one man operation, safer - cheap.
30 launches per hour possible.
Aerotow clubs like ourselves could easily say to members I'll give you
$30.00 towards putting petrol in your car if we go winch - based on a
$40.00
tow to 2,000ft or a $10.00 winch to 2,000 which we can achieve at
Warwick.
Just makes sense.
But what's the max glider weight you can launch to 2,000ft? Alice with
water ballast is 650kg max and there are heavier gliders than that around
(eg Nimbus 4 and 4D) which can go up to 850kg.
