[giardini]

Red Cross lifesaving taught me a similar technique: approach the drowner from behind and underwater. You go under the water and feel your way up from his legs to the back of his thorax staying in contact. When you get to the surface you cross an arm over one shoulder and under the other and pull the drowner backward into a prone position face up. Surprisingly, once you've got a hold on someone in the water its easy to stay behind them no matter how they move.

I never gave much thought to the effect this might have in open water if the drowner did not see you approaching - suddenly something underwater is grabbing him and controlling his movement - Jaws!8-))
