I saw an illustration with Thai captions that showed the front diver basically bearhugging the kid. Can't find it now. But I was wondering how that would be possible--I've seen one of my neighbors do it with their teen but in reverse (teen had the octo and was hanging onto mom's tank). If the rescuers are bearhugging the teens, it seems like they'd have more control--at least until they got to constricted areas (as long as the teens were neutrally buoyant or just slightly overweighted).
Think about restriction where it is barely big enough for an adult to go through without tank. This arrangement gets the boys ready to go through it.
Six boys came out. So this setup works for them.
