There's a lot of SUPs where I'm at. Most of them don't know what they're doing, but you can't really tell them that because all of them look like John Cena.
There was about 6 or 7 of us out at one jetty. SUP guy comes and sits outside the lineup... It didn't bother me so much until he was flailing on the inside. That board will definitely do some damage if it hits you.
