RedactedNarrative: Operator of Boat was anchored at a nearby rafting area. He boarded the vessel to leave, started the engine and began retrieving his anchor. While doing so, a hook on his anchor line punctured the soft tissue between his thumb and first finger. A nurse practitioner that happened to be nearby used gauze and bandages to slow the bleeding and a medical glove to secure the bandages. He transported himself to the hospital and needed 5 stitches.
