Vessel 1 was being operated at night on Lake Sam Rayburn without the navigation lights on due to glare.  The passenger was using a spotlight to watch for stumps when he saw a fish and began to follow it with the light. Unaware of a stump ahead the operator continued on his path striking the stump shifting the bow fishing deck backward, stricking the passenger and breaking his leg.
Operator completed the report.
