RedactedNarrative: Watercraft #1 was going west on the lake with a person surfing behind it. All occupants were watching the surfer, not looking in front of the boat. Watercraft #2 was facing north to south and was stationary while the occupants were fishing. They saw WC #1 heading toward them but were unable to start their engine to move and WC #1 collided with them in a T-bone fashion. There was damage to WC #2. There were no injuries. Life jackets were not being worn, and alcohol was not a factor.
