Operator of vessel #1 struck something at night in the fog causing property damage to his vessel.  According to him he had no idea what he hit nor that he had damage until the following morning when he looked at his vessel.  Our agency was called by the Marina because another vessel that was moored came in at the same time as vessel #1 with damage to it that indicated that vessel #1 struck vessel #2 causing property damage to both vessels.  No injuries.
