After moving from wind foiling to wing foiling, I've finally cracked the code & know I can do this. Next steps are moving to a smaller board (I have a One 130 Ltr ready to go) and moving off my Slingshot I99 trainer wheels to my AFS full carbon foil(which really goes). The AFS has a deep tuttle built in to the mast so only option is a power adapter.
Surf Sail Australia are currently sold out of these. Do any other dealers sell the power adaptors?

thanks,

Greg

I know this doesn't answer your question regarding adapters but the Patrik AIO wing boards have both Tuttle and US boxes which makes them very adaptable. Been using my 5'9" 115 litre for a while now with Armstrong HS foils and it goes great. Also have AFS W95 with 1080 and 700 foil wings which I am hoping will feed the need for speed this summer.
Construction is full carbon/pvc sandwich and very light.
Would love to try a One board but not many in the UK I think.

Thanks Gorgo. That's what I need.
The SurfSail Aust one is the other way around- to mount a foil with Track base to a board with Tuttle box.
