I recently took the PADI Rescue Diver certification, had been a lifeguard in my youth and currently participate in long distance swimming events (1 - 2 miles) and triathlons. I can tell you that according to the Rescue diving course the correct order of btilly's recommendations would be 2, 1, 4 and possibly 3 (while implementing 4). It should go without saying, but your immediate course of action is to call for help and/or designate someone to do so in case of an actual drowning situation. Your preferred choice of action is to stay out of the water entirely. Do not get in the water unless you must. Use any means at your disposal from lines to poles to thrown floatation devices to safely assist the victim. Keep eyes on the victim, assign someone to do so as well - in case you need to gather emergency equipment (above or swimming aides like mask/fins if they are available and if you are going in). Next would be a wading assist, again, waist/chest deep wade into the water with a line/pole/floatation device. Finally, if you must enter the water remember that YOUR SAFETY is above that of the victim. If you allow the victim to overpower you, you will become a victim yourself. The most powerful tool at your disposal at this stage is your voice. Talk to the victim, reassure them, let them know you are there for them and everything will be ok. Reel them back from the edge of panic. After that, the next powerful tool at your disposal if you are overtaken by a panicked swimmer is to dive and push the victim away from you while under water - the victim will not follow you down. Rinse repeat until the victim calms down, you get a hold on them from behind, or they pass out. Having the victim pass out is not the worst thing that can happen. It may require rescue breaths and/or cpr once you get the victim to shore/boat.
