Vessel 1 was travelling from east to west, under sail, with the red/green/white masthead light on.  As Vessel 1 approached Ashtabula Harbor the Operator checked for approaching vessels and, seeing none, went below to check a navigation chart on his laptop.  The Operator states that he was below for less than one minute.  Vessel 2 was headed northeast out of Ashtabula Harbor when the Occupants aboard Vessel 2 saw Vessel 1 and, after unsuccessfully swerving to avoid collision, Vessel 1 collided with Vessel 2.  The bow of Vessel 1 struck the starboard side of Vessel 2 causing significant damage to both vessels and resulting in two injuries aboard Vessel 2.
