We couldn't place this run on the map yet — endpoints read from the run name.
Season
Eyewitness account posted September 2024; no recurring season established
Water
Unbroken South Shore Oʻahu swell wrapping around a point and continuing past Diamond Head
Experience
Advanced open-ocean foiler with current Oʻahu route, current and rescue knowledge
Hazards
Open-ocean route with unpublished endpoints, track, distance, wind, swell, current, reef depth, vessel traffic, bailouts and rescue support. The foil discipline is also unspecified.
Parking & access
Do not use the schematic route pin as a launch. The forum names Black Rock and Diamond Head but withholds the shore entry, landing toward town, parking and shuttle.
“A Progression Project forum contributor reports witnessing South Shore Oʻahu downwind foilers come around the point at Black Rock, connect unbroken swells past Diamond Head and continue toward town. The post does not publish a start, finish, track, distance, support plan or foil discipline, so the coordinate is a schematic route-area pin rather than a launch.”
