For generations, ocean athletes have tested themselves across the Kaʻiwi Channel. Canoe paddlers, prone paddlers, surf ski racers, SUP athletes and foilers have all faced the same challenge: cross the stretch of open water between Molokaʻi and Oʻahu and see what you can do. 

For Armie Armstrong, that journey began on a SUP in 2011, and in 2018, after plenty of petitioning and support from the foil community, the first foil division joined M2O. There were only around eight riders on the start line, but their speed showed what the young sport could become. The early equipment was basic by today’s standards. The foils were much larger, the boards were short, and everyone was still learning.

“We were hanging on for dear life.” 
 
Since then, the equipment and skill level have progressed enormously. Riders are using smaller, faster foils and connecting open ocean energy in ways that once seemed impossible. 
 
While almost everything around it has evolved, the foundation of the Armstrong system has remained consistent. The same mast and fuselage connection (A+ System) used in those early races is still at the heart of the system today, with every surrounding element continually refined.  

For Armie, that progression is both exciting and humbling. The next generation is already linking ambitious interisland crossings and taking downwind foiling into new territory. 
 
But M2O remains unpredictable. A set wave in the final moments can change the entire race. 

 
“The ocean is the master, and it has the final say.” 

The gear will keep evolving. The athletes will keep getting faster. But the Kaʻiwi Channel will always set the challenge.
