One foggy November afternoon, Lige heard splashing and a faint cry. A young boy, the son of a neighboring oysterman, had fallen off a dock and was being swept out by a strong current. Before Lige could even turn the boat, Chessie launched herself over the side. She powered through the chop, reached the struggling boy, and nudged him onto his back. Grasping the boy’s collar in her mouth, she towed him to a sandbar, using her floating rear harness for extra buoyancy. By the time Lige arrived, the boy was shivering but safe.
