HYDROGRAPHIC REFRACTION, TAKEOFF & EXIT CHANNEL PROFILE
Beach & Reef Bottom ProfileWellenmechanik (Riff (Reefbreak)): Langperiodische Dünungszüge (13s+) brechen sich unmittelbar am submarinen Vulkanschelf und bündeln 735 kJ an Wellenenergie in der Takeoff-Zone, während die Welle sauber abläuft. Die benachbarte Fahrrinne leitet das Wasser ruhig ab, ohne Surfer in die Impact-Zone zu ziehen.
