How about the JP Wing Air? I'm seriously considering to get one.
It has decent nose rocker, release rail around the entire tail, d-rings for straps and what I've been told - 42cm long tracks!
But it has no handles. And is cheaper than Fanatic here in Europe.
"Track Foil Plate: The board features a Track Foil Plate of the same size as on our hardboards providing a big range of foil placement. The G10 material adds additional longitudinal stiffness to the hull."
Favorite Beaches: Various spots at our local lake. OBX and Jekyll Island
Gear: F one Rocket Air, Fanatic Aero 2000 foil, Naish S26 and slingshot wings, Peak 4 5m, Pansh Genesis 3m, 6m, Flexifoil kite buggy, Peter Lynn Kite Monohull kite boat, many self made traction kites including single skin NPW's, single skin foils, close cell foil kites, and my own designs. Various windsurf sails and Exocet RF81 and ISups.
STX also has a range of inflatable wing boards that does have side rails. I'm not familiar with that brand, though they are now available in the US. I haven't found a video.
It seems that the STX definitely doesn’t have any plate reinforcement to aid in rigidity. I think the FOne is similar in that.
Even worse, the Fone has a fixed mount 90x160mm making it usable only with Fone foils.
I looked at the STX inflatable wing board as their SUPs price/performance is quite good, to find out they don't have a size between 80 and 160 litters?!
The 80L with 22" width would be tricky for learning and the 160L/29" as wide as my SUP is definitely a no go for me.
I don’t disagree fluidity. I am impressed how far they’ve come though.
Definitely further to go.
I think, hard under shell, dual level top inflation. A bit like some of the inflateable boats. Needs a low but rigid area for foot work dropstitched above deck and a lower pressure dropstitch tube wrapped around sides and front.
