The following waves appear in chronological order. (Know of a high-impact perfect 10 that we left out? Leave your comment below.)

A huge rotation in his round three heat, although it suffers somewhat in subsequent comparison to Jordy’s 9.97 and his own effort at Bali in 2013. Still, a pretty massive turn. Photo: Ed Sloane

Kelly Slater managed an incredible six perfect 10s in 2013, and while he had only one 10 in the Pipe Masters (against Joel Parkinson in the semis) he caught another five waves in the comp as perfect as this one. Photo: Jeremiah Klein

A massive alley-oop which led to discussions about which was bigger; this one of Julian’s or John John’s earlier in the year at Keramas. “In a freesurf I probably would have pulled the eject button like halfway through that air; that was for sure the biggest alley-oop I’ve ever done.” Julian said afterwards, giving an indication of how huge this thing was.

In absolutely perfect Cloudbreak, Kelly nailed two tens in his quarterfinal against Seabass and then another in his final win over Fanning. All three were indisputable. And if he hadn’t been clipped on his first wave in the final (the now-famous open arms close-out claim in this photo) he would have probably scored surfing's first-ever 15. Photo: Tom Servais

Now known as the “Uber-oop” John John’s alley-oop was the biggest, highest and fastest and most f--ked up aerial ever seen in competition. There was absolutely no hesitation, this was a 10 for all the right reasons. (In the same comp Parko scored two tens in one heat -- although many believed the first one in particular was overscored -- while Kerrzy also nailed one.) Photo: Ed Sloane

A full rotation in the final that redefined performance surfing...at least for a few months. Josh Kerr said, “That thing… was… absolutely… messed up. And really, really well executed. It was definitely one of the bigger no-grab-to-the-flat full-rotations I’ve ever seen.” Despite this wave, Slater still lost the final to Fanning. Photo: Ed Sloane

Epic 10- to 12-foot Chopes saw 10s dropping like flies, but Jeremy Flores' outstanding ballsy surfing all event was rewarded with two tens in his Round Five heat. “My first was really good and they gave me a 10. And the second was even better; I knew they had no choice,” said Flores afterwards. Photo: ASP/Robbo

Absolutely flawless Jeffreys Bay and one of the world’s smoothest styles, plus an eight-second, end-section barrel combine to give a unanimous 10-point ride. Who's looking forward to J-Bay again? Photo: Alan van Gysen

Kelly toys with perfect Padang -- first with a no-hands pit over the first ledge, then a ridiculous foamball bucking-bronco-ride to the finish. It was so good, a later under-the-lip tube stall and switchfoot barrel only netted him a high-seven. Photo: ASP/Kirstin

Not just a ten, but a ten with less than a minute to go to win the Pipe Masters over arch-rival Kelly Slater. Looking back, the wave remains worthy on its own, but in the context of surfing history, it might just be one of the best 10s of all time. Photo: ASP/Karen. Video: Marc Beaty
