RedactedNarrative: Vessel-1 was headed north on the Peace River just north of Heard Bridge Rd in Hardee County.  The operator of Vessel-1 turned the vessel to the right to head south. A dog on the front of the vessel slid from the right side to the left side, causing the port side gunwale of the vessel to dip down. Vessel-1 overturned to the left, capsizing the vessel.  The vessel floated south down the Peace River as it sank.
