Tost's cable handling notes prohibet the use of a swivel between the cable
and winch parachute They say it destroys the multistrand cable.- Swivel is
only to be used for towing out.
THis is counter intuitive - can anyone offer an explanation why this is
so?


Thanks

If you use a swivel the cable will untwist when under tension and then turn
itself into a rats nest when the tension is removed. My club uses a swivel
that doesn't work when under tension. I'm not sure it would twist during
towing out either. As far as I can see the only purpose of the swivel is to
prevent the cable twisting as the parachute spins on the way down after a
launch.
