I think you guys are missing the point, the TAG program, from what I can see, is not about educating you, it's about marketing you.
You want to stand out and be recognized as the Professionals you are.
And that includes having some form of licensing or certification so the guy sitting in Toronto or New York can look at your ad or website and have confidence that he is booking with a safe qualified skipper, not Harry from down the street who guides on the weekends to make the boat payment.
The Medical/First Aid, TC inspections, etc are things that you already have, or should have, anyway.
As for success as a fish catcher, you're still on your own, but maybe they'll have enough info in the charm school section that you can keep the customer happy on those rare fishless days.
