650M in elevation is approximately 1800-2000ft?
take that up to 3000ft or more on a 45C day.. our 235HP tow with a heavy 2
seat glider can manage about 400fpm rate of climb, now add some down draft
(sink) or rotor and I've actually had negative climb rates.. I would not
want to be doing that in a 100hp tug

Wrong.

We're using the Katana Extreme itself (100 oomph, which isn't even the
strongest one you can get) for towing in Niederoeblarn (concrete, 700m
runway, 650m elevation, up to 35 degrees Celsius). Up to moderately
loaded glass single seaters. Also possible for light dual seaters.

some have done duty to tow ultralights aloft. Check out the USHGA web
pages.

Ultralights themselves are used to tow gliders hereabouts. There was a
towing competition in Zell am See recently, and the best ultralight was
comparable to a Husky (don't remember how many oopmh).
