A sudden and powerful wind gust triggered a high-speed collision between the Black Foils and Team France during this month’s SailGP event in Auckland, New Zealand, an investigation has revealed. The incident, which occurred just 15 seconds into the third race on , resulted in significant damage to both boats and injuries to two sailors, reshaping the competitive landscape of the season.
Louis Sinclair, a grinder for the Black Foils, sustained compound fractures to both legs in the crash. Manon Audinet, the strategist for Team France, suffered internal abdominal injuries. Both athletes have since been discharged from hospital and are recovering at home, though their participation in upcoming events remains uncertain.
SailGP officials released the findings of their technical review on , concluding that there was “no evidence of system malfunction” contributing to the accident. The investigation, led by SailGP’s director of performance and engineering, Alex Reid, pinpointed a rapid increase in wind speed as the initiating factor.
According to Reid, the Black Foils’ boat, Amokura, encountered a gust of wind while accelerating towards the first mark at approximately 90 kilometers per hour. This surge in wind pressure caused the foiling catamaran to lift higher out of the water, increasing its “ride height.” This seemingly minor adjustment proved critical in the sequence of events that followed.
As the hull rose, the leeward hydrofoil momentarily pierced the surface – a phenomenon known as ventilation. This destabilized the boat, initiating “a very fast chain of aerodynamic and hydrodynamic events” that unfolded within seconds. Data from onboard telemetry and simulator recreations confirmed this rapid progression.
Despite attempts by flight controller Blair Tuke to regain control, the Black Foils began to sideslip, generating lift in unintended ways. The rudder briefly lost its effective flow, causing the windward bow to dip sharply. The boat rounded into the wind and decelerated rapidly, placing it directly in the path of the approaching French F50.
Traveling at roughly 86 kilometers per hour, the French team had no time or space to react and avoid the collision. The impact was unavoidable given the closing speeds and the Black Foils’ sudden change in trajectory.
“There is no evidence of a system malfunction or structural failure prior to the incident,” Reid stated. “What we see in the data is a very fast chain of aerodynamic and hydrodynamic events that pushed the boat beyond its controllable envelope at that moment.”
The incident has resulted in an eight-event-point penalty for the Black Foils following a penalty review that upheld the on-water decision that New Zealand breached rule 14 (avoiding contact). France was deemed to have had no reasonable opportunity to avoid the crash, absolving them of responsibility.
Impact on the SailGP Season
The crash has significantly impacted both teams’ seasons. The Black Foils, representing New Zealand, were considered strong contenders for the championship. The extensive damage to Amokura and Sinclair’s injuries represent a substantial setback. Team France also faces a challenging road to recovery, both in terms of boat repairs and Audinet’s health.
Peter Burling, driver and team boss of the Black Foils, described the incident as “horrific” last week, acknowledging the team’s misfortune. “We started off race three and were going down reach one to windward of the Italian boat. We ended up high on the foil and ended up sliding sideways,” Burling explained. “We hit a system limit, which drastically escalated that situation, and had to take quite drastic action to avoid the Italian boat to leeward, which resulted in us touching down. Obviously, the incident followed that.”
Both teams have been ruled out of the upcoming Sydney Sail Grand Prix as they focus on repairs, and recovery. This absence will undoubtedly affect the overall standings and competitive dynamics of the event.
Mitigation Strategies and Future Safety
SailGP officials are now examining potential mitigation strategies to help crews better manage similar gust-driven scenarios in future regattas. This includes reviewing flight control systems, refining training protocols, and potentially adjusting racecourse configurations to minimize the risk of similar incidents.
The incident underscores the inherent risks associated with high-speed sailing and the importance of continuous improvement in safety measures. The F50 catamarans, capable of reaching speeds exceeding 100 kilometers per hour, demand precise control and quick reactions from their crews. Even minor fluctuations in wind conditions can have significant consequences.
The SailGP league has consistently prioritized safety, implementing rigorous protocols and investing in advanced technology. However, this incident serves as a stark reminder that even with the best precautions, unforeseen circumstances can arise. The ongoing investigation and the development of new mitigation strategies demonstrate a commitment to learning from this experience and enhancing safety for all participants.
The focus now shifts to the recovery of both Sinclair and Audinet, as well as the rebuilding of the damaged boats. The SailGP season will continue, but the events in Auckland will undoubtedly linger as a cautionary tale and a catalyst for further advancements in safety and performance.
