The OP is a new diver was/is clearly anxious about blue water diving. Not uncommon. She and her buddy started a drift dive with lightning nearby, something we are told is not so unusual for the area.
She was buddied with a much more experienced diver who brought along a speargun.
Because of equalization problems, she felt ill soon after reaching the bottom, and thumbed the dive. She and her buddy ascended to the surface, where she dropped her weights.
At the surface, she discovered the boat was too far away to do a pick-up, the seas were rough and there was lightning in the area. Despite her clear distress she managed to deploy a safety sausage, and hold onto it for at least 45 minutes. Her dive buddy saw the boat leave the area and tried to shout to it. When the dive boat didn't respond, he spent the time waiting for pick-up searching for more game to spear in the close vicinity of the OP.
We have no indication why the dive boat left the area, we don't even know if the dive boat moved at all. We do know the divers surfaced some distance from the boat.
The original dive boat eventually picked them up. The OP was quite distressed and upset. I don't see any indication of real panic. Nor did anyone require medical attention. (If I got anything wrong please correct)
My Obsevations:
Teaming a speardiver with a less-than-confident new diver was a poor plan. Speardivers on this board have often told us hunters hunt solo. The OP needed the full attention of her buddy, at depth and on the surface.
The boat briefing may have included more information about recovery if the dive boat had to leave the site. Something as simple as "when you surface, if you can't see us, deploy a sausage and wait" might have eased some of the anxiety the OP had on the surface. I don't know how much of a briefing is customary on these boats, perhaps the OP could have been more proactive about finding out what to do in that situation before she got in the water. In reality, I'm sure she was relying on her more experienced buddy. Trust-me dives are not a good plan.
How to handle the lightning: A really interesting question. Clearly, being underwater is best. The simplest way to ride out the storm is to deploy a SMB, and use it to hang around 15 to 20' deep until the storm passes. Lightning is very apparent underwater. The buddy team should have stopped their ascent around the 15' mark, shot a bouy and hung until the storm passed.
At that depth air will last a long time. The OP couldn't do this because she dropped her weights and it is unlikely she was trained to deploy a SMB on a line. The buddy might have been trained and equipped to shoot a SMB, but he couldn't re-descend without leaving the OP on the surface.They probably weren't prepared to do it, and probably didn't have the gear. Once the OP was on the surface without weights, the buddy team had used up all it's options.
My conclusions:
Be prepared to lose the boat. (Bring signaling gear)
If there is lightning in the area, be prepared for an extended hang. (Bring and know how to use an SMB)
Buddy teams must have good commmunications about likely contingecy plans before the dive. ("since we're seeing lightning before we begin the dive, if we ascend and see a wild ass lightning storm, stop at 15 feet, I'll deploy the SMB and we'll hang until the storm passes")
And to the OP, If all else goes wrong, and you are at the surface in a horrible storm, drop your weights and ride it out. This is what you did, it saved your life. Not a bad dive after all.
Good diving.
