Two things: First GypsyDiver as an Instructor you dive with someone whom you deem unsafe it is your responsibility to help educate them to be a safe diver. What happens when they dive with someone else and they hurt them self or someone else.
Second MBayDiver some boats don’t care it’s all about money to them and they will take anyone who is willing to pay. I have seen it first hand. I tell my students not to dive on those boats. If they choose to dive on them it’s their choice. Nothing is more important than continuing education, especially when it comes to courses such as cavern, cave, deep, re-breather, tri-mix, solo diving, and wreck penetration.
I say get the training; furthermore tell your instructor you would like to continue diving with them after the course. If they will not dive with you don’t get trained by them. Plain and simple if they are not willing to dive with you after you take a class with them then find another instructor who will.
