In the video, I never saw anything that implied the Skater was faster than the Fountain, but quite a lot that showed the Fountain pulling away easily, and handling the very few waves with aplomb. Quite an impressive piece for Fountain! Why is it on the Skater site? Well, I guess its pretty impressive that any cat can hang with the Cat Killer.
Seriously, both those boats were smoking! The Fountain was clearly faster, however.
