First thank you for posting. It takes courage and others may learn from it.
Now to your question. Did you act correctly, absolutely! No doubt about it. Clearly the two divers in question were panicking, or near to it and getting them positive in the water was the first priority.
Was diving a group a problem? Not realy.
What was the root problem? IMHO 4 things
1. You had to add air to their BC. Why was there not air in their BC already? There should have been for the swim out. When I first get into the water there is a period of adjustment when air, trapped by the suit slowly is displaced by a thin film of water. They slowly went from positive to negative as they swam the 60 yards, hence the near drowning feeling.
2. Lack of physical conditioning on the part of the divers. It appears that fatigue played a role here. The exercise of putting on the wet suit and the short 60 yard swim tired them out. Note to self, exercise, run, ride a bike etc. Diving requires physical conditioning.
3. When switching to snorkel she did not clear it before inhaling, or else the end was caught on her gear and under water. I ocean dive every week or more often. I always swim out on my back, it is more efficient and you could not see anything anyway. The snorkel is a tube of say ¾ to 1 inch diameter. That does restrict your breathing a bit. Add to that the possibility of breathing rapid and shallow with the anticipation of the dive in limited visibility and you have the I cant breath syndrome.
4. It does sound like the two divers were wearing a lot of weight. I cant say for certain. But I salt water dive with 20 pounds of lead, 7 mm suit and hooded vest. I weigh 148 lbs. So in fresh water I would wear less weight. You will have to look at the weight issue yourself as I lack enough data to comment. Many dive instructors over weight the students to help them get down and stay down during instruction. New divers tend to take a big breath before trying to go down (which adds buoyancy) and then unconsciously move their feet in a bicycle motion (fin or swim up) when trying to go down.
5. This dive had potentially 4 inexperienced divers. Only one diver had any dives outside of the classroom environment. I would recommend diving for a short time with other dive buddies who have a lot more experience. At least until each of you had say 12 or more dives under your belt.
Now go find an experienced dive buddy, and get back in the water diving, all of you.
