I think it's important to not build the Galapagos into somewhere it isn't. It may be somewhat challenging diving but I don't think it's necessarily particularly challenging diving with the appropriate experience and there are plenty of places that present very similar challenges no douby closer to home.
Having been there twice I completely agree. That said, it's certainly not for the novice diver.
Further, there is rarely if ever any indication on advertised trips regarding the prohibitive nature of conditions, the proximity or lack thereof of medical facilities, or the ratio of divers to dive guides, for example. In terms of practices, the operators almost always state that they put the comfort of the client first for a dive experience of a life time.
Perhaps we,as traveling divers, should have our own checklist of questions and prerequisites which we can review with dive operators prior to booking a vacation that address such issues?
All good points. On my first trip to the Galapagos, there clearly were divers there that should not have been. The conditions on that trip were much calmer than the second. Still, the two teenage boys on the trip who were there with less than 50 lifetime dives clearly should not have been on the trip. They were routinely exceeding depth limits (they were diving nitrox) and seemed to me to be accidents waiting to happen. Although the currents were relatively mild and the seas were calm, we were still doing a lot of blue water diving looking for whale sharks. I felt that we were fortunate that everyone returned safely from that trip. On my second GA trip, one of the two divemasters became very ill early in the trip and was unable to dive for more than the first couple of dives that week. So, there was a single divemaster in the water for 14 divers. Thankfully all divers were very experienced and self sufficient. It would have been a difficult week if there were a lot of divers who needed a lot of hand holding and even as it was it was sometimes difficult to find divers in the high seas even though everyone was shooting sausages from depth on their safety stops.
The key really is to be informed and prepared for the potential conditions. Don't rely on a dive operator to make the decision for you regarding whether or not you have sufficient experience.
