Deff looking for a yoga specific board.
If she wants to surf she'll get her proper board.
Just didn't know if there are learner SUP boards or if having surf skills can allow you to have a smaller board or something.
Ha ha, yeah I say that too, then grab the SUP 9 times out of 10 for a surf. Trust the guys above, she will venture in to the surf with it and then......BAM....Addicted!
But being a competent surfer and the size of a sup board for yoga is probably not relevant. Bit like saying I'm a competent kiter so I can poleboard. You'd probably take her weight into account and google yoga sup and find a link something like:
www.the-house.com/learn/best-sup-yoga-stand-up-paddle-boards/Or, wait for someone who knows something about yoga SUPping to give a definitive answer.
Good luck.
