I actually witnessed a guy and his 17 year old son putting there 21' bayliner in the water. The dad got out and climbed in the boat after he had gotten the boat in the water, the kid put it in reverse by mistake, panicked and ended up jumping out of the truck as the truck and trailer went under water and floated under the dock. The kid was standing on the ramp and the dad was watching from his boat as his truck and trailer sunk. It was kinda funny and sad at the same time, no body was hurt except the kids pride. I'm sure he had some explaining to do to his insurance company.
