Question: The picture of the throwable shows a line snaked around the life ring which would make sense for grabbing the ring. Or should the line be attached to the throwable as a line to pull the person back to the boat?

Answer: The rule states that Throwable devices shall be "immediately available." But our training shows that good practice is to have a line attached so you can pull the throwable back in if you do not get it close to the target and to be able to pull the person back to the boat as well.
