[WARNING] When setting up a Spanish Windless
do not use nylon or other synthetic fiber
rope that stretch under a load. If you slip or
let go of the poles the energy you used to stretch
the rope will be released as the rope returns to
its original length. This release of energy could
cause the poles of the windless to spin around
causing injuries to any one near by. Natural
fiber ropes, such as sisal, have little stretch;
therefore are much safer to use.
