We rode behind a Bazooka last weekend, see the link:

The Bazooka hull is similar to the Centurion Wave. Gekko bought the molds from Centurion. I believe that they have since modified the hull. The Wave was the first wakeboard boat hull designed specifically for wake sports.
I like the layout of the Bazooka. The only down side is on cold days there no escaping the wind. Not everyone is a doctor, lawyer, big building contractor, or Indian chief, and so not everyone can buy a top three boat. I’d leave a little room and respect for other brands and entry level boats.
Demo the boat then decide. Ohhh, and my boat is for sale
