If we're not refreshing ourselves, we forget things. It's the same with a driver's licence. I think it might actually help, even if you have to do a 20-minute refresher when you get your boating licence, because you do forget things.
She is correct in that if you're not going out every day and you're not on the waterways every day, you might not even know what those buoys stand for. You have to figure it out. I've heard of people losing their entire propeller because they didn't understand the navigational buoys, so they need refreshers. People need to remember that they're not going to remember it.
There could be work done on that. It is people's responsibility, however, to do that work before they get in a boat. It is based around education. You have to remind people, “This is your responsibility. Go and learn.” I'm noticing that with everything, so it's not just one thing.
