For 27 years, the contest at Teahupoʻo had been judged from a wooden tower roughly 150 m² in footprint, anchored to the reef on temporary fixings. The tower came down after each event window and went back up the next year. It was not pretty; it was not permanent; nobody from the village had a strong opinion about it because there was nothing to have a strong opinion about.
Paris 2024's original proposal was different. A new three-story aluminum tower, ~322 m² footprint, with full air-conditioning, indoor toilets, and capacity for roughly 40 judges and broadcast personnel. Cost estimated at €4.6 m (~$5 m USD). It would require fresh foundations drilled into the reef and a barge-served construction window. Critically: it was designed to be permanent — not for the Games alone, but for every Tahiti Pro that followed. The tower was framed by Paris 2024 and the French Polynesian government as "Olympic legacy infrastructure."
The first organized opposition came from Vai Ara o Teahupoʻo, a community association based in the village. Its president, Cindy Otcenasek, became the principal local voice in French and Tahitian-language coverage. The association did not oppose the Olympics being held at Teahupoʻo. It opposed the specific proposal to drill new foundations into a reef that had hosted the WSL contest for decades on temporary wood.
The international amplifier came from Matahi Drollet, a top local Teahupoʻo surfer who launched a Change.org petition and a parallel social-media campaign. The petitions, taken together, gathered more than 200,000 signatures, and Drollet's specific petition was reported at ~98,000. Kelly Slater — five-time Tahiti Pro champion, the most-published surfer in Teahupoʻo's modern history — publicly endorsed the campaign in late 2023. On 10 November 2023, a march in Papeete brought the dispute onto national French television.
The science came from the MEGA Lab. A Hawaii-based marine science nonprofit, working with the University of Hawaiʻi and Vai Ara o Teahupoʻo, used 3D photogrammetry to baseline the reef inside the proposed tower footprint. They identified 1,003 coral colonies across 20 species in the ~322 m² site. They warned dredging and construction could affect up to 2,500 m² of reef — beyond the tower footprint itself, accounting for anchor swing, barge passage, and sediment plumes — and result in at least $1.3 million USD in direct ecosystem damage. The MEGA Lab study was published in the journal *Remote Sensing*. Their pre-Games baseline was set up specifically to enable a post-Games comparison.
The first physical incident came in December 2023. A barge mobilizing equipment for the new tower snagged and broke a section of coral at the construction site. Photographs of the damaged colonies circulated within hours. Paris 2024 paused construction. The pause was brief.
On 19 December 2023, the International Surfing Association — then led by Fernando Aguerre — publicly proposed scrapping the new tower entirely and judging the event remotely from a combination of land cameras, water cameras, and drones. The ISA argued that the WSL had judged Tahiti Pros for years without a permanent structure and that 2024 could be done the same way. The French Polynesian government rejected the proposal, citing legacy infrastructure as a precondition for hosting. The ISA proposal died.
What got built was the compromise. A smaller, lighter aluminum tower with a footprint reduced by ~25 percent — back to roughly the original wooden tower's 150 m² footprint. Capacity 25-30 people. Foundations were shallower than the original aluminum design but still drilled into the reef. The tower is collapsible and is intended for re-use at future Tahiti Pros, which means the "permanent" framing held even after the design shrank.
The Games went ahead in their original window: 27 July to 5 August 2024. Kauli Vaast — a 22-year-old surfer born in Vairao, the commune seat ten kilometers from Teahupoʻo — won gold for France with a final-round 17.67. Caroline Marks won the women's gold for the United States. On the medal podium, Vaast spoke about Teahupoʻo as his home break. The world audience was 11.6 million for the men's final.
The post-Games picture is incomplete. The MEGA Lab baseline was designed for a head-to-head with what comes after; that follow-up reassessment is in progress as of early 2026. The comprehensive published damage-vs-baseline report has not yet appeared in the literature. Anecdotal observations from Vai Ara o Teahupoʻo members report visible damage at the foundation drill points and around the construction-period barge tracks — but the scientific quantification is the document that will matter for the precedent the case sets.
Why it matters. The international press cycle on the tower fight framed it as an environmental story — a reef vs. a contest. It was that, but it was also something larger. It was the first time the IOC, an international sport federation, a national government, and an indigenous community at a contested sport-tourism site had to argue, in public, in real time, about who gets to decide what counts as legacy. The compromise that got built is the precedent. The 25 percent reduction is the lever. The MEGA Lab's coming reassessment is the next move.
