So I have not found any issues with the fit of this boat. The seat moves forwad fairly easitly, but as others have mentioned you do need to pull and cut the pilar to move the seat far forward which I did, but not a big deal as it keeps the pilar really solid. The boat does not have any initial stability until it gets up to hull speed on a wave, then it is rock solid. Speed and hard carving are unbelievable in the kayak. So it shines on waves where regular play boats can do notthing but strait surf. The other amazing thing is that this boat is super loose, spins on super glassy slow waves are effortless. I have apddled many play boats and none compare to how loose this kayak is. The place where the Element really shines is in its carve, once you get it dialed you can actuall cross a wave in a hard car nearlly 90 degrees to the current, hit the shoulder, cut back hard and carve back across the wave 90 degrees to the current, if your timming is right and the wave lets you you can actually get covered up by the wave breaking from your first carve. I also found that this boat blunts just fine and can initiate airial moves from a back surf verey well but you loose hull speed greatly when back surfing. Also I know some folks have had an issue with this boat catching waves or plaining out but I have not found this to be an issue at all, even with my weight. Last on the flat water the boat actually cartwheels and loops fine, I have an IR overthruster on this boat and can slam out loops with no problem, in a hole or on the flat water so although surf specific it still can hang with the Play boats a little!
