RedactedNarrative: Vessel #1 was traveling northwest on Lake Lorelei.  In an attempt to steer away from vessel #2, vessel #1 decreased the throttle and subsequently lost steerage and maneuverability.  As a result, vessel #1 collided with vessel #2 (which was at dock) striking the outboard motor.  The operator of vessel #1 was taken to an area hospital and treated for lacerations.
