Excuse me for appearing stupid, but I was under the impression that
you needed a CG hook to winch launch and that a Schweizer hook was
especially bad to use because when the tow cable is approaches 90
degrees to the release arm, the bale (name? *thing the pilot actually
moves during a release) is under so much load that it cannot be pulled
aft. * * I'd like to know more. *Thanks, John
Snip...
I've winched launched 2-33's a lot from the nose hook with no
problems. *My greater concern is fouling the strop in the skid. *Not
aware of any that have failed to back release at the power cut that
I've launched, but the pilots always pull twice anyway. *Plan B is cut
the rope.

"What Frank said." For several winters back in the (I think) 1990s various
SSB-ers used to winch launch our nose-hook-only-equipped 2-33. Other than
noticeable elevator separation/porpoising on the way up if one "over-pulled",
all was utterly straightforward. Of course we did "the usual pushover" at the
top of the arc, firmly/fully pulled the release twice, and visually verified
successful release before initiating any turn. Plan B was to chop the
(single-strand, well-logging) wire at the winch. Plan C was to circle to a
close-in-to-the-winch landing pointed at the winch.
Never had a hook-related/release issue of which I was aware. Plan A always
worked without drama.

So.......................I could winch launch my glider using the nose
mounted Tost unit?
That would be great!
Brad
you might want to ask Bob K first 
Stan Hall was not a fan of winch launching on a nosehook and from what
i've read made it pretty clear that he did not design the cherokee for
ground launch loads. *Didn't stop some people though and I know of at
least one winch launch rip the wings off fatal in a Cherokee II.
Although odds are there was something not quite right with the wings
too. *There is a Cherokee in Australia that is regularly winch
launched although that is with a tost hook on the CG and firmly
attached to the fuselage bulkhead that includes wing attach at the top
and main wheel at the bottom, in other words, very tough. *I'll stick
with aerotow.
Hi Tony,

Not a Cherokee, this glider had fluttered previously on an aero tow
launch in Boulder and was refused further launches. Evidence of water
damage in structure. Doubled weak link unknown to winch crew.

Probably responsible for Charis no longer insuring steel wire rope.

I thought this was an L-13. I believe the glider impacted several
parked power aircraft.

Yoke problem
Still, I find no Cherokee II winch launch incidents. Details please.
I have a FACEBOOK proposition for you.
