Cinematic Nordic Big-Wave Surfing on Wooden Sailboard

Cinematic Nordic big-wave riding shot, filmed like raw 35mm documentary footage. A woman rides a colossal cold North Atlantic wave on a primitive wooden sailboard, wearing a medieval water garment of thin linen and leather wraps with simple tribal bindings, soaked and clinging naturally. The wave forms a massive wrap-around barrel, a dark steel-blue wall of water fully encircling her, creating a long tunnel of collapsing water that she glides through. Heavy mist and spindrift tear off the lip, turbulent water roaring around her. Camera follows close from behind inside the barrel, water-level perspective showing the tunnel closing behind her. Raw cold-water physics, natural overcast light, grainy film texture, ancient tribal mood, no modern elements, 16:9.
