RedactedNarrative: Operator of vessel #1 stated to the effect: I was looking for the entrance to the marina to spend the night.
  I am unfamiliar with the area and the aids to navigation is almost nonexistent. I struck the underwater
  pilings.
  
  Investigation revealed: Vessel #1 was traveling southeast on Sandy Hook Bay (Atlantic Highlands
  Borough, Monmouth County) approaching Atlantic Highlands Marina's west inlet from the northwest.
  The west entrance of the marina is marked by 4 fixed navigation aids and 2 buoys, it is only safe to
  approach the inlet from the northeast. Vessel #1 struck the submerged ruins (abandoned pilings), which
  is clearly marked on navigation chart #12401 (see partial navigation chart on page #4 diagram). Most of
  the pilings are only visible during low tide. The collision was the result of vessel #1 operator's lack of
  knowledge of the area, failure to reference nautical navigation charts and the fact that most of the
  pilings were not visible due to high tide. Vessel #1 sustained damage to the port hull bottom, including
  scrapes and scratches, and both propellers and rudders are bent. No injuries were reported. Vessel# 1
  was towed to Atlantic Highlands Marina by Tow Boat US and immediately hoisted out of the water.
