Kelly Slater and Kalani Miller are expecting their first baby

Surfing - 20. Март 2024 - 14:49

Kelly Slater and Kalani Miller announced they are expecting a baby. It's a boy.

The 11-time world surfing champion and California-born swimwear entrepreneur Kalani Miller are going to be parents.

The couple broke the news in a collaborated black-and-white Instagram Reel posted on Tuesday, March 19, 2024, to Ben Harper's "The Three of Us."

Interestingly, March 19 is Father's Day in many countries.

Slater, 52, and Miller, 36, will have their first child together. The soon-to-be mother will give birth to her first child in 2024.

The American surfer has a daughter from a previous relationship with Tamara Michelle.

Taylor Slater-Kelleher was born on June 6, 1996. She has gained recognition as both a photographer and a painter.

Kelly and Kalani have been dating since 2008.

They met at a Quiksilver booth in California when Slater was competing in Lower Trestles and Miller and her sisters were working in Roxy.

Miller once revealed she would love to have two or three children with the professional surfer.

A Business Couple

Kalani runs her company, Mikoh, with her sister, Oleema.

Their line embodies their vision of modern swimwear for women, drawing inspiration from their experiences living in bikinis and exploring oceans worldwide.

Oleema, a former professional surfer, leads as the creative director and designer of Mikoh, infusing her extensive travels since age 13 into the brand's aesthetic.

Meanwhile, Kalani utilizes her education to manage the business side of Mikoh.

The brand's name is a fusion of their surname, Miller, and the initials of the sisters along with their younger sister's name, Hana.

Additionally, "Miko" originates from Japanese, signifying "female shaman" or "female prophecy."

Kelly Slater is the greatest professional surfer of all time.

The Floridian holds the records for being the youngest (1992) and oldest (2011) men's world surfing champion at 20 and 38 years old, respectively.

Kelly Slater's business ventures include Kelly Slater Wave Co. (wave pools), Outerknown (apparel), Slater Designs (surfboards), Firewire (surfboards), Endorfins (surfboard fins), Solento Tequila (beverages), KLLY (sandals), and others.

Top-to-bottom surfing: the art of drawing a line on a wave

Surfing - 18. Март 2024 - 19:11

Surfing is all about working the unbroken wave face and maximizing riding time. But how can you optimize and balance these two goals that cancel each other out?

Many things separate a beginner surfer from a pro surfer.

However, there is one that stands out immediately after each one takes off on a wave - the way they draw a line or trim it.

Unlike a snowy mountain, a wave is in constant mutation.

As a result, surfers have to adapt their riding to the shape and breaking of each wave differently, whether they're going left or right.

Drawing a line on a wave is choosing the ideal path or trajectory to get the most out of the clean, open face and riding for the longest time possible.

Naturally, if you're spending too much time on cutbacks, off-the-lips, and carving maneuvers, you'll lose the "train," i.e., you'll get caught by the whitewater and end your ride prematurely.

Waves don't wait for surfers. They're on their mission.

So, it's up to surfers to read them, adapt, make the necessary adjustments in real time, and then expect to squeeze the waves' potential to the end.

In other words, a perfectly ridden wave is all about timing the surfer's speed to the natural behavior of the moving water.

A common rule of thumb in surf coaching states that the difference between a beginner and an advanced surfer is the line drawn on the wave.

Vertical Surfing

A first-timer will draw a straight line from beginning to end, while an experienced rider will engage in the so-called top-to-bottom surfing.

Let's put it visually:

The yellow line represents the novice, who will catch a wave and ride it straight toward the beach without making the most of its available space.

In the book "Secrets to Progressive Surfing," Didier Piter calls the rider of the white line a "passive surfer."

"The surfer rides the wave's face passively sideways in a linear trajectory called 'trim line,' which enables him to keep balance," notes Piter.

"At this stage, the surfer uses the speed and energy provided by upward motion in the wave face. He uses more of the wave's energy and extends his trajectory over more of the wave."

This straight line could be easily improved by applying pressure on the inside rail, releasing pressure, and then applying it to the outside rail.

The result will resemble a horizontal, stretched S-line that sees the surfer generating speed across the wave face, as shown in the green line.

Experience will bring more dynamic and vertical, top-to-bottom surf.

At this stage, as seen in the orange line, sharper and more abrupt horizontal S-style lines will be drawn on the open wave face.

The surfers will start moving up and down the wave, taking the most out of the wave height, keeping close to curl and on the steepest section.

At the utmost level, represented in red, the line drawn on the wave will be a sum of extremes, going super low (trough) and super high (above the lip) and extremely tight and compact.

The advanced surfer is constantly compressing and uncompressing the body and shifting their body's weight in the right direction, driving off the bottom and eyeing the lip for vertical hacks.

Managing the Moments of a Ride

The concept of top-to-bottom surfing does not necessarily apply to every wave and every moment of the ride.

There are times when an advanced surfer has to choose a higher straight line, for instance, to find space inside the barrel.

And there are also times when a mid, curvy line is the right option to generate speed before launching into an air trick.

The only moment staying low on the bottom of the wave is the right choice is to set up an aggressive bottom that will slingshot the surfer to anything he wants to do next.

On a perfectly breaking wave, the surfer manages the space and time available, ensuring they never lose momentum and are always within close reach of the pocket, the main energy source in a wave.

Reading the ocean and choosing the right wave is, therefore, a prerequisite to advanced surfing.

"When paddling, reading the wave is mainly horizontal, to evaluate what it will do overall, to assess the speed and rhythm with which it will break," concludes Piter.

"Once up and riding, reading the wave also becomes vertical so that you can use the entire slope to execute maneuvers."

The ultimate goal of the surfer is to aim high and low, further and deeper.

The historic swell of March 7, 2024 at Cloudbreak

Surfing - 13. Март 2024 - 15:16

On March 7, 2024, Cloudbreak delivered one of the most epic swells in Fiji's big wave surfing history.

The use of superlatives has become commonplace in journalism and writing in general, and sometimes, we need time to let the dust settle and process the information.

However, you can't ignore the facts and the footage as they, in this particular event, could easily replace the role of words.

Unexpectedly, for this time of the year, or maybe not, the famous small island of Tavarua was the center stage of a massive big-wave riding showdown.

The first signs of this anomaly issued an XXL Code Purple alert that put swell hunters on high alert. It was time to quickly book flights to the South Pacific Ocean archipelago.

Surf media followed, with a dozen photographers and videographers eager to shoot anything that moved inside the massive blue cylinders.

Remember June 8, 2012, and the "Thundercloud"?

If so, do know that March 7, 2024, nearly matches its grandiosity in size, energy, rawness, and perfection.

Early in the morning, Cloudbreak was firing 20-foot bombs down the reef.

Nathan Florence, Billy Kemper, Conner and Parker Coffin, and Benji Brand met at Tavarua and got in the boat to the infamous break at sunrise.

Soon, the lineup was invaded by around 30 souls wishing they could have a go at one of these turquoise gems.

Into the Blue

The minutes and the hours passed, and the waves only got bigger and bigger, hollower and hollower, heavier and heavier.

At 11:30, the tide and wind conditions were perfect, and the glassy giants paraded on the catwalk.

Timing the paddle-in was an exercise of geometry punctuated by grains of luck, though.

At a wave like Cloudbreak, triangulation is never quite possible, and Nature's acts of randomness make it impossible to find an optimal take-off position.

The liquid curtain that fell down on every swell pulse was thick and relentless. If a surfer were too deep, he would surely be punished.

But even if you found the sweet take-off spot, you could get engulfed by a faster freight train.

The view from the boats on the channel was mesmerizing and increasingly hypnotizing.

"Every single person that entered the water and rode a wave got one of the waves of their life," said Nathan Florence afterward.

The Fijian lefthander proved to be a dream big wave arena for the regular footers, but surfers like Parker Coffin and Che Slatter made goofy footers proud and inspired to push.

The blue skies and offshore winds were as enthralling as misleading.

Billy Kemper suffered one of the wipeouts of the day after free-falling on a huge avalanche of saltwater. But he was not alone in this league.

More than a succession of waves of a lifetime, everyone was somehow getting to the essence of what it feels like to be alive and of how life really is precious.

The strike mission to Cloudbreak was a resounding success.

Soli Bailey, Jai Glindeman, Mick Davey, Mark Visser, and many others were surfed out. They could only be.

"Today is a day that will go down in history," expressed Billy Kemper.

"I've been surfing for over 30 years now, and I can count on one hand how many days I've seen like that."

Waves of a Lifetime

For many surfers, it was the best day of their lives.

"Every hour, we were saying, 'How could it get any better than this?' And it just kept getting better. We all got the waves of our lives. I've never seen barrels that big and been in barrels that big," added Benji Brand.

Reality exceeded the surf forecast and weather models' best expectations for this Southern Ocean storm that popped off-season.

"We always expect this crazy thing from crazy numbers, and this one had small numbers, and way overperformed. It was epic," concluded Jojo Roper.

Laura Enever got some fresh Fiji tattoos but was more stoked than ever.

"To be honest, when I saw the first bombs come through this morning, I wasn't sure I was going to make it off the boat," confessed the Australian big wave charger.

"I ended up watching for a while, then giving it a crack!"

"I got to be in the front row of some of the craziest tubes I have ever seen. I got some visions, a wild beating, and lost my earrings."

Kohl Christensen, who seems to be everywhere simultaneously, took time to reflect on this "surreal" experience.

"Waves you dream about, the ones you would draw in your notebook while staring out the window in school," wrote Christensen.

"Beautifully shaped cylinders with the perfect lip line, running at the precise speed - no need to pump."

"Deep water swells hit the reef at the sweetest possible conjunction, and cyan caverns slow down time and space for those inside and out."

"It's' days like this that transform surfing into a transcendental experience."

There is a new entry in Cloudbreak's history. It's March 7, 2024, the day a few human beings had the best waves of their lives.

El Buey: the big wave oasis of the Atacama desert

Surfing - 12. Март 2024 - 18:18

It's one of the world's most out-of-the-radar big waves and certainly one of the most exciting surf breaks in Latin America and the South Pacific. Bienvenidos a El Buey.

Arica is a well-known surf town in the north of Chile, which has been attracting surfers and bodyboarders for decades.

The region showcases a chain of exciting reef breaks, breaking close to the shore on the wave-rich Alacran Peninsula.

These shallow, hard-breaking lineups like El Gringo have achieved international notoriety since the Rip Curl Search landed in 2007.

At the time, even the world's best surfers struggled to tame the local tubes. Eventually, Andy Irons defeated Damien Hobgood in the final.

The truth is that Arica, the "City of Eternal Spring," is highly consistent for swell and light winds.

The small urban community is located in the coastal heart of the world's driest desert - Atacama.

The Bull

Despite the many options available in the vicinity, there's one gem that stands out. It's called El Buey or The Bull, in English.

It's not as famous as Chile's cold water temple, Punta de Lobos, located 1,365 miles (2,197 kilometers) south, but it surely demands respect and should not be underestimated.

El Buey is a big wave arena breaking 0.25 miles (400 meters) west of Arica's Playa El Laucho.

The offshore beauty is considered one of the best peaks in Chile, providing perfect, fast, and tubular left and right-hand waves.

El Buey can withstand any size swell. It reminds us of waves like Waimea Bay, Mavericks, and Sunset Beach.

The left-hander will focus S-SSW swells into booming barrels, while the right will wall up anything with more W in it and offer steep drops and roller coaster walls. 

The spot can hold 20-foot-plus (six-meter) waves, but there have been surfers lucky enough to take on 40-foot (12-meter) walls of saltwater.

El Buey is quite wind-sensitive, though, and needs an E offshore breeze to pop up in grand style.

Low and mid-tide are the best periods to surf this Chilean beast with sand and rock bottom.

A Heavy A-Frame Barreling Wave

Locals often check its conditions from Morro de Arica, the sand-covered hill that overlooks the Pacific Ocean.

Interestingly, El Gringo and El Buey seem to work coordinately; when the former is unrideable, the latter shines to life.

El Buey has always been low-key on the international big wave surfing scene.

Nevertheless, the Chilean surf break is home to the Santos del Mar Invitational, a competition that attracts international riders.

Ramon Navarro, Cristian Merello, Rafael Tapia, Gabriel Villaran, Miguel Tudela, Carlos Burle, Danilo Couto, Lucas Silveira, Rusty Long, Nick Lamb, and Kohl Christensen were only a few of the big wave riders invited to the prestigious event.

In 2022, Peruvian charger Cristobal de Col found a large, deep, and hollow cavern, stayed pitted, and found the exit to ignite the spectators of the event.

In the end, he stated that he waited 22 years to ride that wave.

The Long Paddle

If you plan to surf El Buey it is important to observe the positioning of the locals in the lineup and be accustomed to inflatable life vests.

A successful ride at the Chilean open ocean wave can take you 200 yards down the line, especially the right-hander.

The deepwater surf break is more consistent from April to August, i.e., autumn and wintertime, because the wave only starts breaking at eight feet (2.4 meters).

The left-hander will produce cylinder waves with S-SW (190-210º) swells. The right will work with swells coming from over 220º swells, that is, more westerly wave trains.

The best way to get to the lineup is by boat or jet ski.

Nevertheless, besides Playa El Laucho, it's possible to paddle from Hotel Arica's nearby parking lot or El Gringo.

It's a long paddle with occasional overhead closeouts, so it's always a tricky call.

Whatever your decision is, wear a helmet. A wipeout here could be nasty and potentially dangerous.

Does ocean water temperature affect wave height?

Surfing - 11. Март 2024 - 19:04

Is there any correlation between warmer or colder ocean waters and bigger waves? What is the influence of temperature on wave height?

When we think about power swells, meteorologists and surf forecasters look into the intensity of low-pressure systems on large oceanic fetches.

Then, they track waves generated thousands of miles from the coastlines and follow their energy-gathering pattern as swells travel toward the shores.

The intensity, duration, and area over which wind blows over the water's surface will dictate the power of a groundswell.

Nevertheless, these are only the essential wave train formation variables.

The existence, for instance, of an underwater canyon near the coastline can then dramatically boost the size of near-shore breaking waves.

One of the best examples is Nazaré's Praia do Norte, where local bathymetry plays a critical role in creating XXL waves.

Poles vs. Equator

But what happens when water temperatures increase?

Is there a difference in wave size or behavior in warmer climates where you can surf without a wetsuit?

Does a wave pool in England perform differently from one in Abu Dhabi? What exactly is the influence of temperature on the life of a wave?

When we look at the map of the world's biggest waves, there's not enough statistically relevant data we can extract to reach a conclusion.

Yes, there are big-wave surfing spots near the Equator line - Jaws/Peahi and Puerto Escondido - but we also have other extreme surf breaks closer to the poles - Mullaghmore Head and Shipstern Bluff.

Also, because of their different surrounding environments and bathymetric characteristics, it's impossible to establish any conclusion or correlation.

Temperature and Density

The only option is to ask science, and the answers are pretty straightforward.

When water undergoes heating, it expands, increasing in volume.

In other words, the greater the water's temperature, the larger the space it occupies, leading to a decrease in its density.

On the other hand, lowering the temperature of water reduces molecular motion, causing molecules to come closer together and occupy a smaller volume, resulting in an elevation of density.

The conclusion is that heated water is lighter than the same volume of cold water.

What about speed/velocity? Does warm water travel faster than cold water?

Does hot water move faster than cold water?

Oliver M. Sun, an oceanographer at the Naval Undersea Warfare Center in Newport, Rhode Island, says it does.

The researcher wrote on the Physics Forum, "The speed of a wave in water is directly proportional to the temperature of the water."

"As temperature increases, the speed of the wave also increases."

"This is because warmer water molecules have more energy and can vibrate faster, causing the wave to travel faster."

Sun notes that "as temperature increases, the wavelength of a wave in water decreases because the speed of the wave increases, but its frequency remains constant."

"This results in a shorter wavelength."

Nevertheless, temperature is not a primary, critical factor in wave velocity.

The speed of water flow is mostly determined by external factors such as the force applied (wind or a wave pool pump), the slope of the surface it is flowing on (sandbanks or reefs), depth, and any obstacles in its path (rocks or islands).

It's worth noting that hot water can appear to flow faster than cold water under certain conditions due to differences in viscosity and density.

Hot water generally has lower viscosity and density than cold water, which means it may flow more easily.

You can witness it, for instance, by observing the flow of liquids in pipes or containers.

Global Warming and XXL Wave Events

Now that we've confirmed that warm water has more volume, occupies more space, and moves faster when compressed than cold water, it's time to dissect the impact of temperature on wave height.

The study of this combination of variables could help weather forecasters and surfers learn more about the ocean's behavior.

However, this unique relationship has never quite been the focus of attention and research from the scientific community.

Never - until recently.

Interestingly, the correlation between warmer world oceans and an increase in wave height is only indirect.

First, let's understand why it is not direct.

"The amplitude of a wave in water is not affected by temperature," Sun stresses.

"Amplitude is determined by the amount of energy that the wave carries, which is not affected by temperature."

"However, changes in temperature can affect the height of waves, which is a measure of their amplitude."

"This is because changes in temperature can cause changes in wind patterns, which can result in larger or smaller waves."

Precisely.

In 2019, Borja G. Reguero, an associate professor at the University of California, Santa Cruz, released the conclusions of a study titled "A recent increase in global wave power as a consequence of oceanic warming."

The study analyzed a potential correlation between the evolution of wave power in the world's oceans and global sea surface temperature from 1948 to 2008.

The results indicate that both variables are strongly correlated.

"The effect of climate change in oceanic warming has been increasing the global energy transferred from winds to the waves represented in the GWP," Reguero concluded.

"The impact of climate warming on the wave climate can therefore be seen in the energy transported by the waves, measured through the global wave power as a long-term signal of climate change."

In other words, the increase of surface sea water temperature results in stronger winds, which in turn mean bigger and longer waves.

Siqi Yang is the first-ever Chinese Olympic surfer

Surfing - 4. Март 2024 - 17:03

Siqi Yang is the first Chinese surfer to qualify for the Olympic Games. The 15-year-old will represent her country in Paris 2024 at Teahupoo.

It's China's best-ever result in an official international surfing competition.

Yang finished the 2024 ISA World Surfing Games in 15th place among over 110 female surfers and secured a historical Olympic ticket.

But the remarkable story of Siqi goes back to 2022.

In a surprising turn of events, China started emerging as a rising force in the world of surfing at the 2022 ISA World Surfing Games in Huntington Beach, California.

The youthful Chinese surfers, led by the then 13-year-old sensation Yang Siqi, shattered expectations and captured the attention of international media.

Traditionally, surfing powerhouses such as Brazil, Australia, the USA, and Japan have dominated the scene.

However, China's remarkable performance at the ISA World Surfing Games signals a potential shift in the sport's landscape.

At the time, Yang, the youngest member of the Chinese team, etched her name in history by reaching the fifth repechage round, finishing an impressive 29th.

Under the guidance of South African coach Wade Sharp, the Chinese team formed in 2018 and showed exceptional dedication and progress in a short period.

Sharp, who previously coached Team Japan at the Tokyo 2020 Olympics, saw immense potential in the Chinese surfers, predicting future success on the global stage.

"They're very dedicated to their sports, and they take their training seriously," Sharp told the Olympic channel.

"I think a few years down the road, you're going to see China right up in the top earning medals, just like all the other countries."

Despite the challenges posed by the COVID-19 pandemic, which limited their training opportunities abroad, the Chinese surfers displayed remarkable adaptability.

Siqi Yang started surfing in 2018 when she was just nine years old.

"I was so scared about it at the very beginning, but after getting through that period, surfing has made me pretty happy."

Siqi's dedication and fearlessness in competition caught the eye of Coach Sharp, who noted she has a "super rad future."

In 2022, China's surfing head coach Wang Xiaofei set its sights on the long-term goal of making a mark at the Los Angeles 2028 Olympics.

"Our goal for LA 2028 will be ranking into the top 8 of the Olympic Games," he stated at the time.

A Stellar Performance in Margara

However, the Chinese surfing dreams arrived a bit earlier, and the Asian nation will be represented in Tahiti's Teahupoo.

The year 2023 was a rehearsal for the upcoming surprise with a 31st finish at the ISA World Surfing Games among more than 120 women surfers.

In 2024, 15-year-old Siqi Yang stepped up her game.

In Round 2 of the World Surfing Games, the Chinese wonder kid beat two-time WSL champion and two-time ISA World Junior champion Tyler Wright.

Yang excelled in the waves of Puerto Rico's Margara with a powerful performance and one of the best single turns of the day.

"This is my first time surfing Margara," the young Chinese gun said.

"Before the event, it was totally flat, so we were surfing El Pico. This wave is amazing, and I just went with the flow."

"For me, I just keep a low profile to try and learn from the experience of surfing with a two-time world champion. Puerto Rico is beautiful. The waves are amazing."

Yang progressed through to Women's Repechage Round 7, where she was able to validate the ticket to the Summer Olympics in Tahiti.

"The Olympic dream is my dream, to qualify for the Olympics," concluded Yang.

"I'm super happy, super excited to accomplish this today. Thanks to my country for supporting me in getting here and to my coach for bringing me to this level. I'm so happy. I've been training so hard for this."

How are surfers seeded into WSL competition heats?

Surfing - 27. Февраль 2024 - 15:22

How are surfers distributed in heats? Can two top-ranked athletes match up against each other in the opening round of a contest? Here's how seeding works in the Championship Tour (CT).

The World Surf League (WSL) introduced a new competition format in the 2019 CT.

The goal was to fine-tune an athlete's past achievements while simultaneously rewarding performance in a running season.

Seeding is the process of assigning a rank or position to a surfer based on their previous achievements or current performance.

Seeding aims to create a structured bracket or draw for the surf competitions, ensuring that higher-seeded athletes are initially paired against lower-seeded ones, theoretically providing a more balanced and competitive progression throughout the event.

In modern competitive professional surfing, each elite surf contest features the following stages:

  • Seeding Round;
  • Elimination Round;
  • Round of 32;
  • Round of 16;
  • Quarterfinals;
  • Semifinals;
  • Final;

The Seeding Round

The Seeding Round (see image below) is the first competition heat and features 12 three-man man heats, i.e., 36 athletes.

The top two surfers from every heat progress directly to the Round of 32, whereas the surfer with the lowest placement in each heat moves on to the Elimination Round.

But what are the criteria for distributing surfers through the 12 heats?

Can two top surfers in the overall rankings meet in the inaugural stage? How do you set up a fair seeding?

For the seeding calculations, WSL designed a system with two variables:

  • Base Seed Points;
  • CT Seed Points;

The Base Seed Points apply to the previous season's CT athletes, the wildcards, and the replacements.

They are determined by WSL before the first CT event of the year and have a gap of 40,000 points between the world champion and the 34th-placed surfer.

The world champion gets 60,000 points; the last in the rankings gets 20,000 points.

The gap is determined by the precise percentage difference in rankings. 

For instance, if the 2023 WSL world champion Filipe Toledo holds 60,000 points and Ethan Ewing lagged 19 percent behind him in the previous year's rankings, Ethan will start the 2024 season with 19 percent fewer seeding points than Filipe.

Therefore, the initial seeding reflects each surfer's performance from the preceding year.

Then, all surfers will have 25 percent of those initial Base Seed Points deducted from each of the first four CT events of the season.

As a result, Base Seed Points will be zero from the fifth CT contest onward.

The goal is to reward performance and allow lower-seeded surfers to get rid of their initial handicap, if you will.

CT Seed Points are the sum of the Base Seed Points plus the current CT rankings points earned in the regular season.

The Brackets Formula

How are surfers seeded into the inaugural round?

Before each event, WSL assigns seeding to the surfers within the range of 1 to 36.

Subsequently, these 36 individuals, including the wildcards, are distributed across four brackets.

The initial bracket encompasses seeds 1 to 4, the second bracket consists of seeds 5 to 12, the following bracket includes seeds 13 to 24, and the last one comprises seeds 25-36.

Consequently, a surfer is confined to movement solely within their designated bracket during the competition.

This seeding system allows wildcards and replacements to have a chance to not draw the top surfers again in Round 32, something that happened before 2019.

In the past, a wildcard who beat a top-ranked surfer would have to meet him again in the previously designated Round 3, current Round of 32.

With the new system, a wildcard that wins the Seeding Round will not be up against a top-four athlete in the Round of 32.

In other words, performance and results are rewarded.

First Surfs Against Last

It's important to note that in the opening round, the highest-ranked surfer is seeded with the lowest-ranked athlete plus wildcards, the second-placed surfer is matched against the penultimate-ranked surfer plus a replacement surfer, and so on.

Only the order of heats was reshuffled mainly to avoid overlapping heats with top-seeded surfers who eventually battle in separate heats for the world title.

In Round 32, the competition adopts a horizontal pyramid-style, two-men, single-elimination format in which the winner advances through to the next match-up and the loser is eliminated.

It's important to underline that the Brackets Stage (see image above), from the Round of 32 to the final, splits the leaderboard into two sides (Heats 1-8 and Heats 9-16), meaning that the winner of each side's heat only meets the winner of the other side's heat in the final.

According to WSL, professional surfing's seeding does not follow an automated algorithm. Instead, heat distribution and organization are supervised manually.

The competitive surfing seed formula is not perfect nor always fair, but that's virtually impossible because the weight of the variables at stake is subjective.

For instance, how do you weigh the importance of winning the Challenger Series (CS) against placing last in the top 22 CS rankings?

Who should be seeded above, a 10th-place finishing CT surfer or a runner-up CS campaigner?

Depression Louis triggers historic XXL swell in Nazaré

Surfing - 26. Февраль 2024 - 14:14

Depression Louis brought some of the largest swells of the decade to Portugal, Spain, and France, courtesy of the North Atlantic winter storms.

The extreme weather event raised national alerts and put big-wave surfers on hold on Europe's infamous XXL surf breaks.

Most storm-chasing fraternity converged in Praia do Norte, Nazaré, for another go at the Guinness World Record race.

The Portuguese underwater canyon has been the gold mine of many athletes and media professionals eager to ride and capture the sport's superlative stunts.

The Code Black swell brought a lot of wind, gusts, and heavy rain but also plenty of record-breaking opportunities for the usual suspects.

Three names in particular have been making a living in Nazaré in recent years: Lucas "Chumbo" Chianca, Sebastian Steudtner, and Rodrigo Koxa.

Whenever Praia do Norte fires its most brutal missiles, they're either strapped to their surfboard or towing someone into the massive avalanches of water.

The big wave surfing business has become a niche industry in the once quiet and picturesque fishing village.

Extreme surfers get the most out of the winter season the best way they can - free surfing or competing in events like the Nazaré Big Wave Challenge or the Gigantes de Nazaré.

The former is run by the World Surf League (WSL), and the latter by Brazil's TV Globo.

Gigantes de Nazaré is an invitational event that explores the monetization of online video content and broadcasting to large TV audiences.

A Potential New World Record

On Saturday, February 24, Nazaré witnessed the peak of Depression Louis, with the beach break detonating 80-foot plus (25-meter) walls of water.

Chianca and Steudtner had an informal duel in the heavy waters, with both the Brazilian and the German entertaining the audience at São Miguel Arcanjo fort and on the cliffs with some impressive runs.

They were towed into the biggest waves of the day by Ian Cosenza and Eric Rebiere.

Some say the current 86-foot (26.21 meters) world record wave has been broken, but no one dares to say by whom and on which wave.

The WSL officials will have the last word, using their fine-tuned wave height measuring method.

Once again, the safety rescue teams were busy driving jet skis around massive whitewater and backwash waves and taking their partners out of the impact zone.

The striking 360s and double backflips are becoming the playful standard for foot-strapped surfers descending long liquid slopes.

They're the signature tricks and bonus factor for the patient crowd watch from the safety of terra firma.

But surprises can happen, and throughout the week, as the swell's energy was building, other players emerged confident and audacious.

Lucas Fink, Balaram Stack, Eden Edwards, Alessandra Marinelli, Lourenço Katzenstein, Will Santana, Kalani Lattanzi, Michelle des Bouillons, Gabriel Sampaio, Manuel Fróis, and Vítor Faria also had their share of stoke.

They will definitely keep an eye out for when opportunity knocks.

The quest for the 100-foot wave is a work in progress, one that will require a flawless and rare combination of weather elements to take place.

Indar Unanue conquers 10th edition of La Vaca Gigante

Surfing - 23. Февраль 2024 - 18:32

The 10th edition of La Vaca Gigante has etched its mark in history.

In a stunning display of skill and courage, 24 surfers, both local and international, embraced the formidable Cantabrian waves, reaching heights of over 23 feet (seven meters).

The waves crashed dramatically against the Cantabrian coast, creating an epic day of XXL surfing in Santander.

Ultimately, the day belonged to Indar Unanue, who emerged victorious, shaking the cowbell and hoisting the coveted milk jug that signifies triumph in this prestigious competition.

The day commenced under cloudy skies in Cueto, with minimal wind. The only sound disrupting the silence was the eager anticipation of waves awaiting their moment to shine.

As the tide rose, the La Vaca Gigante 2024 competition kicked off around noon with the trial round. Seven surfers vied for the last coveted spot in the main event.

The action commenced swiftly, featuring impressive waves and powerful surfing, notably by Frenchman Pierre Rollet, who dominated with 24.11 points, securing a spot in the final phase.

With the main event roster finalized, 18 surfers engaged in three heats of six riders each, competing for a prize pool of €10,000.

The audience swelled as spectators gathered at the imposing cliffs, eager to witness a day of electrifying surfing.

The competition format involved 45-minute heats, where surfers aimed to accumulate points from their two best waves, with the better of the two counting double.

The initial rounds showcased local talent, with Nico García and Nano Riego claiming the top two spots in the first round, earning them places in the grand final.

The second round saw a reversal of fortune, with foreign surfers Indar Unanue and Nic Lamb delivering exceptional performances, securing scores of 25.27 and 25.39, respectively.

A Perfect 10

In the third round, local Juan Merodio and Frenchman Pierre Rollet made their mark.

Merodio achieved a perfect score of 10 on his best wave, contributing to a combined score of 26.90.

Rollet, meanwhile, achieved the highest combined score in the qualifying rounds with 28.27 points.

As the final list of contenders for this year's title emerged, approximately 10,000 spectators crowded the cliffs of Cueto, eagerly awaiting the grand finale of La Vaca Gigante 2024.

With six finalists and an hour-long heat in a challenging sea, the riders faced a formidable challenge.

Patience, talent, and wisdom would be the determining factors in the championship's golden round.

Cantabrians Nico García and Nano Riego asserted their local dominance, securing third and second place, respectively, with combined scores exceeding 20 points.

Pierre Rollet, a standout performer, showcased his prowess with a stellar 9.77 score.

However, lacking a second wave, he narrowly missed a podium finish or the chance to challenge the unbeatable Indar Unanue.

Unanue, in a spectacular display, scored two waves above 9 points - 9.67 and 9.93 - accumulating an impressive combined score of 29.53 out of a possible 30.

The Basque surfer's achievements in this 10th edition of La Vaca Gigante are remarkable. After a hiatus from the competition, he clinched victory, having finished as the runner-up three times before.

"The organization has done a great job and has been right with the call for the event because it is a complicated wave to get the timing right," expressed Indar Unanue, the La Vaca Gigante 2024 champion.

"I came wanting to make a final, and I went for it once I saw myself there."

"I was very excited to win the championship because, after several podiums, I was really looking forward to it. Thank you to all the riders, safety patrol, public, and organization staff for making it possible!"

2020.10.06. Овсорок с Болвой, да леса под Любохной

outdoor.inbryansk.ru - 18. Октябрь 2020 - 0:05

Был в отпуске. Хотелось куда-то съездить, пока тепло и сухо, и чтобы не совсем рядом с городом. В город нужно было вернуться порядка 15-ти часов. На том, с утреца в машину закинул свой велик, отъехал до Любохны, достал его, и в путь-дорожку. Трек на велосипеде – https://nakarte.me/#m=12/53.54408/34.52866&l=O&nktl=Y3cQ8UlY1C7dV0kFdhGXzQ

Напишу кратко о красотах по пути. Не считая осенних…

Овсорок, ближние 2-3 км к Болве. Есть дорожка вдоль, обожаю тут бывать.

Болва. Быков Рог,  так зовётся это место. Сюда бы на закате, чтоб освещено было.

Леса с куявского большака до Калинино – по моему треку на велосипеде вполне проезжи (пока сухо). Очень понравилось там.

От Улемца в брянскую область – настоящий грунтобан. Ещё и ветерок попутно-боковой.

Как часто делаю, заехал на Овсорок в районе устья Бердовки
