Boater operator certificate
 

Actually, this was the Online Boat/US course. IIRC, it
took a very short amount of time to pass the test - maybe
an hour or two - assuming you know it all!

In that case, nearly everyone here should have little to no
trouble passing...

I blasted right through it. If you have a Chapmans on your lap there is no
reason you can't ace it but most of the questions are things you should know if
you are a salt water sailor.
