It is not the max weight of the glider, but the max tension applied to the
hook.
That said, the "weak link" should not be stronger than 1200#.
It does not take 1200# of "pull" to tow a 1200# glider.

Cindy has the formula.. and I'm looking for my reference.

Our club is looking at new tow plane. The plane has a Schweizer tow
hook with "1200 lbs max" stamped on it.
Does anybody know what that relates to?
Is this the max gross weight of the glider or max tow tension or...?
I've tried Schweizer, but they couldn't help since they are no longer
making tow hooks.

Thanks for any insights.
