Re: Jackline tension

Simple mathematics. As Ersatzinger posted above, a 5% deflection is about a 10x multiplication of force. Tighter = more, and it goes up geometrically.

Re: Jackline tension

If you keep your jacklines tight, they will break under load. Theu must have some slack, or the geometry of the pull on them will magnify the force.
