If I may, I'd like to add a few things to what Ms. Ramacieri just said.
You have to be proactive and address the issue at the source. You have to educate learners young and old—those looking to obtain their pleasure craft operator cards—a bit like the system for getting a driver's licence. People can take the test online and get their card without ever doing any practical training to learn how to drive a boat. A young or not-so-young person who has never driven a boat can get in the driver's seat of a $100,000 or $200,000 vessel, and off they go—wherever, however. If the goal is to strengthen awareness around speeding and boating etiquette, you have to go to the source. You have to train young people properly at the start.
I also think that the Safe Boating Guide should include a section on the environment. People have to read the guide when they're learning to navigate a boat or trying to get their card. There has been no mention of the environment in the guide thus far. It wouldn't cost much.
