Does your tow pilot know you're doing this? They might not be happy.


Yes. They actually recomend it.

I've flown a belly hook-only glider (Janus) in strong thermals and
rotor and never had any problem with the rope back releasing due to
going slack. It takes quite a positive backwards pull to make the cage
swivel. I don't think the weight of the rope alone would do it.

It's no fun to find yourself released in a rotor with no real place to
land out below you. And blocking the cage in an aero tow doesn't hurt
anybody, it just makes the CG hook function like a nose hook.
