In this episode, we sit down with Björn Dunkerbeck, the 56-year-old windsurfing legend with 42 PWA World Titles (more than any athlete in any sport), 32+ years with Red Bull, and a personal best of 103.68 km/h over 500 m. Fresh off double-hip surgery and pain-free for the first time in years, Björn joins Luc from Lüderitz, Namibia, where he’s chasing the outright windsurf speed world record during the month-long November window at the infamous Lüderitz Speed Channel. From the early days of 16-knot records in Weymouth to breaking 50 knots in a hand-dug Namibian trench, Björn walks us through the 50-year evolution of speed sailing, the physics of wind angle, water flatness, and why 8–10 m wide is now “as good as it gets” for a channel you can’t fall out of at 100 km/h.
- Channel Evolution & Record Progression: How speed sailing jumped from 30 knots in the South of France to 40 in Saint-Marie-la-Mer, 45 by Thierry Bielak, then exploded in Walvis Bay and finally Lüderitz—where a kitesurfer named Sebastien Cattelan dug the first trench, and six riders broke 50 knots in one week (2012–13).
- Lüderitz 2025 Setup: Björn’s first sessions in “perfect south-easter” conditions, why 45–50 knots of wind is the sweet spot before chop kills speed, and how a scratched fin or lack of starting-area depth can end your run before it begins.
- Post-Surgery Comeback: At 115 kg and 56 years young, how titanium hips have restored confidence, why Severne sails (5.2–5.7 m²), 40 cm Starboard speed boards, and custom fins are dialed, and the mental edge of knowing “I can still do this.”
- Gear & Technique for 100 km/h: Why boards are only 227 cm long / 35–45 L, how you rail the upwind third of the channel, and the art of body-position micro-adjustments to keep a 40 cm board from catapulting in full-power 5.2 conditions.
- Wipeouts & Safety: “Your day is over after a big one.” Helmet + impact vest = minimum; grit + not crashing = the real safety plan.
- Getting Into Speed Sailing: Download the WaterSpeed app (free), track your 100 m / 250 m / 500 m times anywhere, then upload to GPS-SpeedSurfing.com and join the Dunkerbeck Speed Challenge (50+ countries, 10th year running). Start on whatever gear you have—25 knots becomes 30, then 40…
- Family Legacy: Four kids, two girls, two boys. Son Liam (17)—triple U21 wave world champ, former U18 Lüderitz record holder (80+ km/h)—currently training on Maui. Youngest Daniel (13 next week) already ripping waves and speed. How Björn transitioned from pro dominance to proud dad without losing the fire.
- Bonaire & Dunkerbeck Pro Center: 10 years strong at Sorobon’s turquoise lagoon—Defi Wind Bonaire returns June 16–21, 2026 (111 spots only). From 5-year-olds in harnesses to 90-year-olds still planing, it’s the world’s safest speed playground.
- Foiling vs Fin: Björn’s light-wind foil arsenal (6.0–10.0 m² + Phantom 960/1950/910 wings) as low-wind speed training, why foils won’t touch Lüderitz (not enough depth, too much drag), and whether sub-40 cm masts could ever push foils past 100 km/h.
- The Limit? Björn’s take: 100 km/h average on 500 m is very possible; top speed >103.68 km/h likely. Beyond 105 km/h, cavitation theories split the experts—we’ll know when we get there.
- Red Bull Family: 32 years, 800+ athletes, from windsurfing’s early days to F1 and America’s Cup. Plus Björn’s long involvement with Wings for Life spinal cord research.
