You guys nailed it. Its a longer playboat. So as you all have said it won't have the short boat corkiness but it will be faster and more stable on end. The length will also lend itself to running the river better because of the added speed but this boat is a playboat. It has a fairly low parting line for initiating moves. The hull is loose and there is a bunch of volume focused in the middle of the boat.
Since it is 6'6" it will be a different kind of playboat compared to the shorter models but I just spent the day out on a big water play section and had a great time. In fact we sessioned a big wave for an hour that I have no doubt I couldn't have even caught or surfed in a short playboat.
If super short is your thing, which will be easier to throw around, then sure it isn't for you but if speed, a loose hull with nice smooth carving edges, longer stable ends for wheels, and still very good pop on a wave and in a hole sound good to you then you should check it out.
