I have not been attending the same industry meetings as you, but I have heard people say that many of today's divers are not comfortable in the water. In stating this, though, they are not talking about the same thing as you are in this thread. They are talking about comfort in the water as it relates to diving skill, especially safety and buoyancy control.
Skilled swimmers who are completely comfortable in the water before diving but who experience weak instructional practice may be uncomfortable in the water while diving. They may be struggling to swim comfortably because they can't control trim or buoyancy. They may have not have had enough practice with skills like air sharing, checking their gauges, or clearing their masks to feel comfortable performing those skills while diving. That may be especially true if they are diving well up in the water column and have never been taught how to perform those skills in mid water while maintaining buoyancy control.
As I said, I have not been traveling in your circle, but in the circle in which I travel, that is what is meant when they talk about divers not being comfortable in the water.
John, in these meetings at the very mention of training agencies finding a way to improve diver skill, the roadblock to any discussion of how we might be able to arrive at a smarter way to improve diver training is that today's diver just isn't comfortable in the water and therefore isn't willing to work in a scuba class. They'll leave the sport if we do much more than sell them a lifetime certification card. I argue that they are for sure comfortable in the water, just not comfortable with their training as you describe.
I wanted to add another arrow in the quiver for my argument next time I'm in such a meeting. SB helped. It seems that those active or interested enough in diving to join an Internet diving forum assess themselves as quite comfortable. My future argument will be that we need to take that comfort, motivate people to want to meet whatever training standards are set to produce quality divers and the industry needs to retool those standards to take advantage of modern educational opportunities while at the same time finding a better way to train divers to greater skill levels in whatever time frame is reasonable for good instructors to produce quality divers. If in-water time isn't adequate a good instructor can only create a fair student and an excellent instructor can only create a good student. My belief is that it is time we re-examined the way we are training divers and get more agencies to join the 21st century by giving more credit to divers for wanting to excel while finding a better way to help them achieve that goal.
