Investigator observed a red PWC overturned in the water and two people on board a white power vessel.  The operator and passenger of vessel #1  were brought on board the patrol vessel.  Vessel #1 was then owed by the investigating Tooper to Hinkley Marina. At the marina, the vessel was removed from the water. Visual inspection of the exterior of the vessel showed no physical damage that would cause it to take on water.
 
Investigator concluded that vssel #1 was heading south in Barnegat Bay  near Sloop Point, when for unknown mechanical reasons vessel #1 filled with water and sank.
