RedactedNarrative: Vessel ran aground. Operator unfamiliar with the water way and the vessel was traveling east directly into the sunlight making visibility difficult. There was also an astronomical low tide as a result of the autumn equinox. She was in the process of slowing down as she approached a designated no wake zone when she misread the color of the channel markers and went to the wrong side of the #11 marker subsequently striking the sandbar. There were injuries. No damage to vessel.
