RedactedNarrative: Operator #1 stated that during an out bound tide, as he was waiting for the Sea Bright - Rumson Bridge to open, vessel #1 struck a submerged object approximately twenty five feet fromthe bulkhead on the west side of the Shrewsbury River as the vessel was swung around in a clockwise direction facing the bridge. Operator #1 felt a thud towards the stern of the vessel. Vessel # 1 then came to an abrupt stop and stalled. Vessel #1 became freed : however, once started and operating significant vibrations through out the vessel.
  
  A search of the area using side scan sonar was negative.
  
  Investigation revealed that low tide occurred on the Shrewsbury River at 0833 hrs. Although it is inconclusive, it is reasonable to suggest that upon Vessel #1 moving over towards the west side of the river and out of the channel where the water is more shallow, Vessel #1 made contact with the river bottom.  It is possible that vessel #1 struck a submerged 
  object that has since moved with the tides.
