The boat was an Orange County Sherrif boat. According to the wittness the sherrif boat was moving along and swerved into Tims lane to avoid running over him while fishing in his Ganu. The Sherrif boat T boned Tims and sunk it throwing Tim into the sherrifs cage then into the water. The wittness jumped in and helped Tim get to shore then tied a rope to Tims' boat with a seat cushion to alert other boaters. Some good people on the river 4 other guys stopped to help pull the boat out. No help from any law enforcement, not even turning the blue lights on to warn other boaters of a sunk boat. We also noticed the sherrif boat didn't have a flag on it, we were told law enforcement was exempt then told flags are only for wildlife management areas, then told flags aren't REQUIRED anywhere they are only reccommendation. All in all Tim was incredibly lucky. I will be buying and wearing the pfds that inflate on impact.
