Professional surfing is a highly competitive occupation. World title races are increasingly tight. And sometimes it all comes down to the wire.

Modern competitive surfing is an incredible intense sports activity. It's hard to imagine an athlete competing at the highest level that can't throw and land an air reverse, get barreled, and complete a full roundhouse cutback.

On top of that, pro surfers need to combine major maneuvers - classic and progressive - with the three main ingredients of success: speed, power, and flow. And today, the difference between a world champion and a relegated surfer is in the details.

The Championship Tour (CT) is comprised of 11 events, but only the best nine are combined to build the overall individual score. Here's how points are awarded at each event:

1st (winner): 10,000 points
2nd (runner-up): 7,800 points
3rd (semifinalist): 6,085 points
5th (quarterfinalist): 4,745 points
9th (Round 5): 3,700 points
13th (Round 3): 1,665 points
25th (Round 2): 420 points

Even taking into consideration that there are a lot of points at stake, and quite a few events held in different wave conditions, surfers may end up tied at the end of the season.

Past History and Possible Surf-Off Formats

There's been a growing tendency to watch world titles being decided in the last event of the season.

The World Surf League (WSL) Rulebook tells us what happens when the two or more surfers are tied on final rankings points.

"In the event of a tie for any world title at the end of the surfing season, the tied surfers will have a 'surf-off' during the final event with a format determined by the Commissioner's Office," the rulebook states.

The surf-off is surfing's ultimate face-off. It is a conclusive, one-off heat (or eve best-of-three heats, similar to tennis) between the world title contenders that decides and crowns the new world surfing champion.

Interestingly, there has never been a surf-off heat in the history of the men's CT. In 2014, Mick Fanning and Gabriel Medina almost had to play the sudden-death match at the Pipeline Masters.

The only example in pro surfing dates back to the ASP era. In 2011, Garrett Parkes and Caio Ibelli surfed a sudden-death heat to decide the world junior champion. The Brazilian ended up claiming the trophy.

The pro surfing authorities can opt for one-off or best-of-three formats, but in case it happens, they will likely go for three 30-minute heats with 0-minute breaks between each clash.

This will result in a total surfing time of one and a half hours or a total surf-off time of two hours of ten minutes. If the organization is getting out of time, a single heat with a minimum of 35 minutes is the best call.
