RedactedNarrative: Operator of Vessel 1(V1) was northbound in the ICW just north of the Card Sound Road bridge when the bow collided with an unknown floating object.  The object struck at and just below the waterline of V1 bow.  The unknown object then moved along the port side of V1 and caused damage around a side window that was approximately 3 feet above the waterline.  
  
  V1 operator tried to fend off the object after colliding with it and jammed his right, middle finger not requiring any medical treatment.  
  
  V1 started sinking at the bow but commercial salvage was able to pump the water out.  V1 was able to motor under own power to ship yard in Miami for repairs.  It is unknown what was struck.  For contributing causes to this accident, both vision obstructed and hazardous waters were selected.  
  
  Operator was operating the vessel from the starboard helm station that would have reduced his visibility of an item floating in the water that eventually passed on the port side. The hazardous waters were created by a difficult to observe object in the water.  The skies were overcast and rain and storms were in the immediate area.
