If you are wanting to play boat in a pool, I wouldn't recommend the axiom. I have one. And I dint think it's what you're looking for.
The axiom is a freak surf machine. If you want to surf and stern squirt.....get it. I LOVE mine.
It's also a great river runner. Lean forward, and the largish bow plows through holes. Lean back, and you can catch the stern and do huge stern squirts. The edges are a bit grabby, though. But it is a super fun boat.
It is not a flat water play boat, though. Just no way you're sinking that big bow. It's like a creeker up front.
If I were you, I'd be looking at a Varun, Fun, Freeride, or Fuse. They've all got slicier bows than the axiom, and will flat water play a bit better because of it. They're also going to be a bit slower than the axiom.
