RedactedNarrative: V1's starboard rear struck V2's starboard side. V1 was reversing off the dock and had mechanical issues with the shifter. V2 was docked. 
  
  Operator1 was operating V1 in reverse, leaving the dock. V1 began reversing in “full reverse” and Operator1 appeared to be struggling to shift V1. V1’s starboard rear collided with V2’s starboard rear, damaging V2’s rub rail and a small section of fiberglass. After colliding, V1 continued in reverse down the starboard side of V2, ripping up approximately 15 feet of rub rail. Also, a small cleat on V1 left a long (approx. 18 feet) scratch in the gelcoat on the hull of V2. 
  
  Operator1 told me his vessel had mechanical issues (shifter). He said he struggled to shift his vessel out of reverse. Operator1 demonstrated the shifter on the vessel for me. The shifter appeared to be stiff and was not easy for Operator1 to operate. When Operator1 shifted the vessel to forward the propeller did not spin.
