I have a new asym in a sock with a dangling line from the top of the retriever line. Trying to figure out where it goes. See the pix, hoping this makes some sense. The retriever goes to a a small block in the top of the sock that pulls the hoop. A little tight but it goes. The dangling line is the same lighter weight line that runs down the sock. Thx..
I can't be positive but it looks like you have a line attached to each side of the collar. That is normal. It is done to keep the collar somewhere near horizontal as it is pulled down and so working at its best.
it should be continuous, or at least on many asymms it is..
deploy it by pulling on the "upsock" (? lol).. initially gently with just enough tension on the sheet to control the sail...at a point the chute will fill and you will need to rapidly deploy the rest.
this line is usually long enough to tie off to a cleat, but thats not critical...just tidy
dousing is the reverse..ease the sheet fully and haul that sock down
