Coincident with Earth Day BoatUS made its Clean Boating course available free for anyone to take. To check it out clickhttp://www.boatus.org/clean-course/
I was able to sign in with my BoatUS login credentials and then sign up for and begin the class. It's fairly basic, but the content serves as a good reminder of clean practices for both captains and crew as we all begin a new Great Lakes boating season. Enjoy.
