RedactedNarrative: Vessel 1, an 11 ft. PWC, operated by Operator1, who had borrowed the PWC. Operator1 along with his wife were operating the jet ski in Belle Pass in southern Lafourche Parish. As they were operating the PWC, the two found themselves in what they describe as 4-6 ft seas. They got nervous and decided to turn around. As they were making their turn, they jet ski capsized due to the rough water. Operator1 was unable to right the PWC and it grounded on the rock jetty lining the pass. Both operator and passenger were both wearing PFDs at thetime. Alcohol is not suspected as a contributing factor in this incident.
