Once he was freed, floating and stabilized, I swam over to their boat, which was now adrift. I worked my way around to the swim ladder and noticed the engines were both running, exhaust bubbling up from below. I asked the woman if the engines were in gear, but she had no idea and she was starting to panic. I was worried that she may gun it if they were in gear. Not wanting to be injured by a spinning prop, I swam away, figuring that she was not in immediate danger.
