RedactedNarrative: Vessels 1 and 2 were traveling downstream hear the Hwy 10 bridge on the Wolf River.  The vessels were traveling in line, with Vessel 1 behind Vessel 2 at a speed of approximately 30 mph.  A short time later heavy rain began, decreasing visibility.  Vessel 2 reduced their speed to slow no wake, while Vessel 1 continued at their original speed.  
  
  Vessel 1 attempted to slow down to avoid contact with Vessel 2 by letting off the gas, and turning but was unable to turn without any power.  
  
  Vessel 1’s bow and portside struck Vessel 2’s outboard motor engine cover and stern (starboard).  No injuries occurred and the vessels were moved to Chico’s landing.  Operators exchanged contact information.
