Sea state plays a role in how far you set out the kite, Brightenburg says. “The more chop, the closer to the boat you can fly the kite,” he explains. When the water is calmer and/or there are more boats, you need to set the kite out farther, he adds. At the closest, Brightenburg says, he will set out 100 yards of kite line. At the farthest, he will let out 300 to 500 yards of line.
