You know what's funny.
Shortboarders that ride SUPS that hate SUP'ers.
That's me and my mates. Hahaha. Joking, kind of.
I think that's probably why many of us have turned to racing SUP for training and downwind paddles rather than surfing them so much. Many of the people I know who do it were in the surf on SUP 3 or 4 years ago and as it has become more crowded with real wallies that ride them and create pains for everyone it also creates pain for us. Particularly in being associated with them. A good mate of mine just took it up as well, he loves it, he surfs now when he usually would go and drink beer. He hates the wallies already and will not surf if the crowd is around.
Don't get me wrong if I see a fat back bank or wide bank at a point that is perfect for the SUP and there's nobody or not many out I am straight out there. It is so much fun that anyone that bags them just can not comprehend. Think being 7 again and going across your first green wave. If the waves are good though I'd much prefer to ride a shorty, they are still a far superior surf craft IMO. I just get sick of crowds and having toys that throw open the options no matter the day is a great idea for where I live. I also paddle other stuff as well.
Moral of the story: I understand why people hate SUP but I find it so much fun that all I can do is try not to piss people off. If I told you how many times people have approached me in the surf and said 'Oh when we seen you paddle out we were all bummed but you have kind of proven us wrong'. ALSO, some guys that ride SUPS surf way better than you do on your shortboard.
