RedactedNarrative: The vessel left the Everett Marina fuel dock at approximately 2030 on 9-4-11.  The conditions were foggy, calm water and light wind.  The operator's intent was to go up Snohomish River and moor at Dagmars Marina.  The operator was inexperienced with using the GPS unit and the vessel ended up two sloughs to the north in Steamboat Slough.  
  
  The vessel went under a railroad bridge, two bridges for the north and south lanes SR 529, as well as the Interstate 5 bridge.  After passing under I-5 it ran aground on the north bank of the slough and listed approximately 30 degrees to starboard.  As the tide continued to go out, the boat listed over even further to 90 degrees.  Both the operator and passenger were rescued by the Fire Department and transported to Providence Everett Medical Center where they were treated for hypothermia.  
  
  There were no other injuries.  Damages to the boat included flooding, broken glass in the superstructure and gel coat damage.  The boat was recovered on 09/05 by Vessel Assist.
