RedactedNarrative: Vessel 1, with two persons on board, was travelling west heading to Fairport Harbor.  The Operator of Vessel 1 became confused about the location of the entrance to the harbor as a lighted barge was exiting the harbor at the time of approach.  Not knowing that the barge lights were altering his view, the Operator of Vessel 1 continued underway on an incorrect approach to the harbor.  Vessel 1 then struck the outside of the west breakwall between the lighthouse and the far north extension light.  Vessel 1 came to rest on the breakwall head following the collision.
