2.4.2 Floating anchors and high lines
Where an anchor point is not attached directly to a structure , but is instead supported by secondary anchor ropes , it is described by arborists as a floating anchor . Floating anchors can be as simple as a secondary rope
attached midline to an existing climbing line , or as complex as tensioned three-dimensional highline systems that can be trolleyed in multiple directions under load .
