RedactedNarrative: On October 3rd, 2021, at approximately 1732 hours, Florida Fish and Wildlife Conservation Commission (FWC) was on water patrol on the Indian River Lagoon when I received a call reference a capsized vessel with people in the water located at the Sebastian Inlet State Park (SISP) on the south side, beach side access point, Indian River County, Florida. The operator OP1 (swimmer 02) told me he was trolling southbound at about 7 knots, approximately 100 yards from the beach. When an unexpected wave crashed over the port bow, causing the bow to become swamped and forcing the bow underwater, with forward momentum this caused the vessel to capsize turning the left side of the vessel over first. The passenger (swimmer 01) then jumped out of the vessel to the left to prevent the vessel from rolling over on top of him. The operator OP1 was unable to react fast enough, and the vessel capsized with him underneath it. OP1 said he swam from under the boat and surfaced next to PAX1 where they both held onto the capsized vessel until it was pushed onto the beach by the waves.
