RedactedNarrative: Vessel #1 was disabled with a tow boat, with light activated, off of its port stern.  Vessel #2 was trolling with planer boards out 75-100 yards. 
  
  This was a head on passing situation passing Starboard to Starboard. 
  Vessel #2 then passed Vessel #1 and Vessel #2’s planer board passed on the port side of Vessel #1 and starboard of the tow boat. 
  
  As the planer board line passed over Vessel #1 it snapped and struck a passenger on vessel #1 causing the passenger to lose part of his ear.
