RedactedNarrative: On September 26, 2015 at approximately 1500 hours, a vessel accident occurred, with an injury, on the ICW in Flagler County.  V1 was southbound, towing a tuber (who was sitting on the tube facing away from the V1), on the east side of the channel.  The operator thought the tuber was outside the wake on the starboard side of the vessel (towards the middle of the channel), and when he realized the tuber was outside the wake on the port side (shore side) of the vessel he slowed down.  The momentum of V1 and the tube carried the tuber into the skegs of a v2 that was out of the water on a dock lift.
