Here's a link to an online boater's safety course. You can study online and then take a test. I ran through it a few years back. I was digging through my PC weeding out old bookmarks and came across it. I would highly recommend it, most of it is common sense stuff but it wouldn't hurt to check it out. Even if you are not a boat owner but occasionally fish on a boat with a friend or guide, it doesn't hurt to know some of the basics.
