I have a pair of these guys. NIce ski's, and supposedly seat two, but get real unstable with 2 people on it. I think the newer PWC are a lot more stable. Not good for pulling someone on a tube, knee board, or wake board... too unstable. But they are still a good time for a single rider, and are very maneuverable, and when you totally dump one upside down, its very easy to right.
