Cross anchoring involves connecting the kite to the ground at two anchor points. Two anchor points spread the flying load and prevents the kite from wandering too far left or right. Another anchoring option to create a long flying tether. Anchor both ends of a main line across the wind, and then connect several kites directly to the tether. This maximizes the number of kites that can be flown in a limited space.
Many people use swivels at the end of the line to minimize twists.
We advise against that. Swivels are a weak point in the system. Only use swivels on things that rotate. Attach your line to the kite or anchor using a larkshead knot . Higher up, they appear smaller.
