RedactedNarrative: On July 31, 2021 at approximately 11:00am a vessel with two occupants (operator), traversing through a bayou in close proximity to Flat Bayou in ST. Bernard Parish, struck a stationary object located in the center of the bayou at (N29*53.822, W89*44.599) operating at 20mph - 25mph. The object is described to be a steel tube encased in concrete submerged under the water 4 - 6 inches. The water depth on this date was approximately 4 - 6ft. Upon impact of the submerged object the boat was stopped as the object remained stationary. After the collision, the operator reversed the vessel away from the object and drove it on the near shore line. The operator then drove the vessel back to where he believed the object to be in order to observe what he struck. While doing so he once again struck the object at a reduced speed. Once confirming the object, the operator drove the vessel back to “Eddie Pintos marina” in New Orleans, LA. No injuries were reported. Significant damage was  reportedly caused to the fiberglass near the keel of the vessel. The damage to the vessel is expected to cost $1500-$2500. PFD was used. Impairment not suspected.
