I have ridden one on flat water and they seemed to be fine I think it was an uli. They are great for kids as they can fall on the without any issues. Also safer in the surf for a beginer and those arround them. Also saw them at the Mambo in the surf and they went ok too.
I think Oliver or Jonathon had one for some time they would be the best people to PM and could give you more information.
