RedactedNarrative: Vessel one was returning to Hemenway Harbor after spending the morning on the Lake. Vessel one was approximately half way across the Boulder Basin, between Sentinel Island and Boulder Island when the vessel had a unknown equipment failure. 
  
  Vessel One was adrift and waves up to two feet swamped the vessel. When Ranger Vessel arrived vessel was approximately half under water, with occupants standing in the boat with water up to their knees. When the Ranger vessel approached all occupants went to one side of the vessel, causing the starboard side of the vessel to sink and the vessel to go vertical in the water. All occupants of the vessel went into the water. Occupants were wearing life jackets and were all safely brought onboard Ranger Vessel. No Injuries.
