The SeaCleaners Ambassador
Mathis Ghio, five world titles and an engineer's perspective on the ocean
A native of Marseille who grew up with his feet in the water, five-time wingfoil world champion, and materials science engineering student at INSA Lyon, Mathis glides just inches above the water's surface, where plastic pollution cannot go unnoticed.
His commitment
“It's not just talk, it's engineering in service of the ocean”
“I chose The SeaCleaners because it's an association that takes concrete action in the field, with real technical solutions. That truly resonates with me as a future engineer.”
“What I want to bring is my visibility and my voice to a community of ocean enthusiasts, but also my presence at spots and competitions around the world, to highlight the reality of pollution wherever I foil and inspire people to take action.”
His track record
30 metres
That was the distance separating him from victory at the World Cup in Turkey when his board struck a massive plastic bag. He ultimately crossed the finish line in 9th place.
What drove him to act
A flawless race, stopped dead in its tracks by a plastic bag
“I had led the race from start to finish. Just 30 metres from the line, I ran into a gigantic plastic bag. My board came to a sudden halt, I was thrown about fifteen metres forward, and I found myself swimming mid-race to recover my gear.”
“That's when you realise that plastic pollution isn't a distant or theoretical problem: it's right there in the water, and it has very real consequences. I'll never forget that race.”
Profile
Mathis, off the podium
In real life
Curious and hardworking
“A Marseille native who grew up with his feet in the water, and just a regular student whenever I head back to Lyon. I enjoy tinkering and fixing my gear myself, and I remain a down-to-earth person.”
The surprising detail
A hobby that turned into five world titles
“Wingfoil wasn't supposed to be my discipline. I was competing at the top level in iQFOiL and rode wing purely for fun. Today, I'm a five-time world champion in a sport I took up just for recreation.”
His sport and the ocean
Impossible to look away
“Wingfoiling takes place just inches above the water's surface, in total silence, with no engine. You see everything: drifting debris, shifts in water colour, marine life right beneath your feet. You simply can't pretend not to see it.”
His vision
Watersports athletes: witnesses and voices for the ocean
“I hope this partnership shows that watersports athletes have a role to play, that we aren't just users of the ocean, but also its witnesses. I want this to inspire my own partners and the wingfoil community in this direction, and encourage other athletes to take meaningful action.”
Italy, 2016
“No battle is lost in advance.”
Trailing near the very back in the only race of the penultimate day, he was ready to withdraw from the Youth World Championships. Re-energised by his coach, he swept all 6 races the next day to clinch the title by a single point.
