Season
Completion documented in November 2025; no recurring safe season established
Water
Very long exposed inter-island Pacific channel crossing
Experience
Expert expedition foiler with dedicated tracking, communications, escort and rescue planning
Hazards
Approximately 100 miles of open ocean with no forum-published endpoints, track, wind, swell, current, bailouts, support craft or rescue procedure. The foil discipline is also unspecified.
Parking & access
Do not use the midpoint for navigation. Establish lawful Oʻahu and Kauaʻi endpoints, transport, escort, tracking, communications and a dedicated recovery plan.
“A Progression Project forum post records a completed roughly 100-mile foil crossing from Oʻahu to Kauaʻi through the Kaʻieʻie Waho Channel. The post does not identify the foil discipline, start, landing, track or support plan, so the coordinate is a schematic channel midpoint rather than a launch.”
