RedactedNarrative: Operator #1 stated to effect:  We were traveling south in the main channel when we struck something underneath the surface of the water.  The starboard side of the vessel came out of the water causing the vessel to cant to the port side.  First I checked on injuries, and then we immediately responded to Spray Beach Yacht Club because the vessel was taking on water.
  
  Witness #1 stated to effect:  We were following our GPS to watch our water depth.  We just passed one of the markers heading south when we struck something under the surface.  The boat leaned hard to the port side and the stern came up.  We started to take on water and went right to the dock.  
  
  
  
  Investigation revealed:  Vessel #1 was traveling south in the vicinity of Intracoastal Waterway marker #95, Long Beach Township, when it struck an unknown submerged object.  The object caused a large portion of the keel to crack and split from the hull resulting in the taking on of water.  The vessel was removed at Spray Beach Yacht Club.  Damage was observed to a large section of the keel starting about midship to stern.  The vessel had to depart the scene as it was rapidly taking on water.  Due to the fact the vessel departed the scene, I was unable to determine what had caused the damage to the vessel.  TowBoat also responded to the scene.  No injuries were reported.  The owner of Vessel #1 was below deck in the cabin at the time of the accident.
