RedactedNarrative: At about 2130 on 4 july i was a guest on m/v aida. We were proceeding out of the approaches to carr creek at idle speed (4 knots) headed for the vessels home dock in lake ogleton.  All navigation lights on aida were checked and shone brightly.  I was on the port side of the cockpit area.  In the vicinity northeast of r6 on the severn river we were struck on the port side  by a runabout running at, i estimate, 15 knots.  
  
  I saw the green light on the colliding vessel when it was about 15 yards out.  At that point a close aboard encounter was expected and the captain of the aida had put the engines in reverse.  When the runabout collided we were stopped or nearly.  I saw no actions by the driver of the runabout to avoid collision.  The impact pierced the hull and the runabout was stuck in aida for several seconds.  He eventually extricated himself with reverse engine. At that point, towboat resolute approached and told the driver to stay where he was and that resolute was coming alongside.  
  
  A quick check of below decks on aida showed significant damage but minimal  danger of taking on water. After dnr arrived on scene and sorted out as much of the circumstances as could be done on the water, aida proceeded back to lake ogleton under its own power.
