I agree with Neil, I think there is a problem with
the chute set up. I got my sign off a long time ago
on auto tow and we didn't use a chute. I have more
recently become somewhat active in the Prescott Soaring
Society where we winch launch exclusively, and I am
in no means an expert at this but, our chute systems
all have at least 8 gore lines. I seem to remember
that yours only had four. I would think that the more
gore lines would allow less of the chute to to be exposed
to the relative wind when under tension, each line
holding in less of the chute. Just a thought.

OK, training done, my apologies if I misinterpreted

But I still think there might be something wrong with
the parachute setup - it shouldn't open under the
normal
tension of the tow.
And 65 to 75 mph does seem too fast for the tow car.
I drove tow cars for many years before we changed
over
to a winch, and I don't recall ever going as fast
as
that even in no wind conditions.
I hope you sort out the problem.

It will have to wait until our next dry lake weekend.
The BLM insists
on 6 months lead time to obtain a 'use permit' for
the dry lake.
