So I hung last night under fairly windy conditions, enough that my hammock was occasionally tugged as the trees swayed from gusts of wind. I didn't need a tarp, but the motion of the trees got me thinking. When using a continuous ridgeline for a tarp, is there much potential for the movement of the trees to snap the line? The hammock naturally has some give to it, but not the tarp ridgeline. Are tensioners used? Or maybe it's not really a problem in practice?
