RedactedNarrative: Operator of vessel 1 was operating in a westerly direction at 3 or 4 knots when she saw lights that she thought might be another boat. She states she turned towards the north to avoid it and thought she had clear water but due to an abnormal full moon low tide, the water was not as deep as she thought and she struck a rock at low speed temporarily grounding the boat. Boat towed in by Sea Tow.
