RedactedNarrative: We were returning from dinner from the Pier and headed back to Waterford Marina around 10:30. All boat lights were in proper order. I was traveling at moderate speed and being very cautious since it was very dark. As we were coming around the Point Venture peninsula I was carefully watching the buoy lights and the lights on shore and felt confident that I was in the proper channel since I had just maneuvered this channel the previous two weekends and paid very close attention to the markers. Unfortunately, I was mistaken and since the buoy light seems to be dim and I believe some not even lit, i misjudged and ran aground. About a millisecond prior to hitting the sand bar I saw it and pulled back in the throttle, but it was too late and the boat stop suddenly and thru the passengers forward.
  
  Three passengers were thrown from the boat and only one was cut from something on the boat prior from departing the vessel. One other passenger was throw in the galley of the boat and sustained minor injuries to their body. All other persons on the vessel were uninjured.
  The vessel was removed from the sand bar several days later.
