RedactedNarrative: Vessel #1 was anchored approximately 200ft east of the north of the tip of the jetties. The operator of V1 stated that a large cargo ship that was entering the St.Johns created a 5-7 ft wake.  The wake hit the stern of Vessel #1 capsizing it, and tossing the occupants into the water. The cargo ship was traveling W approaching the Mayport inlet inbound against an out going tide. The strong tidal current may have effected the cargo vessel's wake.
