RedactedNarrative: On July 4,2014 @ approximately 1924 hours, V1 was pulling up to the dock @ dry Dock Restaurant to drop off passengers.  4-5 passengers moved into the bow area to off load onto the dock.  As the vessel approached the dock, it was decided that the passengers would remain on board the vessel & travel to a residence on West Okoboji.  The vessel turned around and headed out into Smith's Bay with the 4-5 passengers still sitting or standing in the bow of the vessel.   The vessel took a wave over the bow, flooding the passenger compartment.  The vessel then began to list to one side before taking on another wave. The vessel then capsized.
