A method that is reasonable simple is to just put the rope into a carrier

bag or canvas bag haphazardly , tie the last end to the bag handle , hook

it on your towplane and walk away, comes out without any knots . Proven
method that rock climbers use and the UK Fire Service use for storing their

ropes. Simple , easy to deploy and just chuck back in the bag , dont need a

truck or hosereel , easily portable. There will be those who say "that wont

work but like all gliding clubs there are lots of negative people. Try it
!!!!
