RedactedNarrative: Vessel 1 was trolling and completing a tum when lines became tangled. Several of the occupants went to the rear to untangle/cut lines when waves began coming over the stern. The added weight of the water swamped the vessel and then capsized the vessel. The operator remained under the vessel for a short time before surfacing. All occupants were rescued shortly after the vessel capsized. Operator became unconscious after being placed on rescuing vessel, CPR was started and eventually Operator was Life-Flighted. Operator was later pronounced deceased.
