first the swivel should "not be tight to the mast", with the swivel in the middle and a shroud on each side there is lots of room for the swivel to be free. Undo the sheet lines and pull the line all the way out, if the line was bunched up it may have been causing the problem. Roll up just enough line to complete furl the jib. I cut the excess off but you could just coil it up and tie it to the tramp.
