I agree with PropNuts. I don't trust the government to implement a safety course program without encumbering it with fees, taxes and a bureaucracy to go along with it. California is intrusive enough in our lives without doing more of it. There are a lot of safe boating courses you can take that have nothing to do with the state. The US Coast Guard has them; so does the US Power Squadron. I took two courses from the US Power Squadron and am rated as a "pilot". The pilot course is very rigorous, requiring over 40 hours of study, and emphasizes a lot of navigation and advanced safety issues.
I think that the people who need a boating course the most are the weekend water skiers and jet-skiers who are in love with speed on the water, and sometimes mix boating with drinking. They see boating as a way to let off steam, and put everyone on the lake at risk. They go too fast, come too close to fishing boats and create huge wakes. Out of all people on the water, they are the least likely to voluntarily to take a safe boating course. They should be ticketed and fined, and forced to take a course. But forcing all people to have a license, with fees, taxes and all that goes along with it is tantamount to punishing the many for the sins of the few. We have laws about boating safety on the books to take care of the problems. The issue is that they aren't being enforced enough.
I know this is about Oregon, but politicians are always looking at the other states for more ideas about how to make money for their state.
