Quoting from their website:
Key to the TRIAK's performance are the static hydrofoils attached to the outriggers. As the boat heels over the float/ama submerges through the water. The foil provides lift starting around 2-3 knots of boat speed and increases exponentially providing significant lift over 5 knots. Not only do the foils deliver great stability but they allow a manageable outrigger size. Instead of large 5-6' amas both TRIAK amas fit snuggly into the cockpit.
Tidalwave - Like you it makes me wonder what the addition of hydrofoils would haave on the AI.
Can anyone come up with a way to add them and give it a test run
I would have thought that unless you raise the ama somewhat out the water, to reduce some drag on the ama, the additional drag that a hydrofoil offers, would just slow you down. But in strong wind, you might be able to have more sail out, without burying the ama, and that would make things faster. I wonder if their hydrofoil can be transferred to an ama? Otherwise we have to make one ourselves.
Notice in this pic the ama is buried, and hes also leaning out?
Actually the hydrofoil looks tiny. Am I reading this right? A bit longer than a mower blade?
and here too:
Interestingly, its about the same weight as an AI, maybe a tad more, but 18 inches longer. It has a 40 sq ft sail, and a 40 sq ft spinnaker, where we have 57.5 furling. But its a busy craft, boom, jib/spinnaker and no sign of a furler. Must be able to do something when 40kt hits you 3 km offshore?
Water is rather smooth in this so called "gale" according to their site. Fellow still has to lean out I see.
My personal feeling is it looks very flimsy, and if you have no boat speed, and get hit by a gust, there's no lift to save you. But for sure we can try out a hydrofoil, and I guess to keep the amas capable of folding, you need to have it on the outside. Attaching it to an aka seems logical, but is going to be an issue for folding. I don't like the idea of drilling mounting holes in my ama, frankly. Guess maybe we could make it clamp right around it?
