RedactedNarrative: On July 6th 2017 at approximately 10:50 A.M. a 19 foot 1981 Hurricane boat, Florida Registration FL 7829 GS, was taking on water while underway heading east in the Bayport channel.  Operator1 stated that the vessel was almost immediately not handling properly. He stated that after the vessel had been underway for a few minutes he noticed it was listing to the port side. Operator1 then checked to ensure the drain plug was secured. He informed me that the drain plug was properly inserted. At approximately 11:00 A.M. the vessel capsized and came to a final rest just outside of the channel near marker 30 (N 28.32.022 W 82.38.830). Operator1 was able to remove the 19’ Hurricane from the water without further incident.
