You will never see all boats compliant unless they pass a federal law against people working on their own boats and find a way to enforce it. As soon as one sinks, somebody screws up another.
As the marinas become compliant, the percentage of boats will greatly increase. You're right, it won't be all. Just like houses. What percentage of house fires are due to faulty wiring and what percentage of that is DIY or unlicensed technicians?
We once had the phone company hook up a box in the garage, fiber optic, that every time it rained, it would kick off. Reason, it was supposed to be hooked to a GFCI outlet and was not, even though there was one ten feet away. The technician who came out to redo it was furious about the previous one and talked about that guy wasn't going to learn until someone's house burned down. I don't know enough to know what the risk really was, but I felt the way it shorted out regularly and flipped the circuit, that it was pretty risky.
