Hi,
I saw a Maui Shaper making one board like this one. Ultra Short, kinda wide and full of Volume.
Gong is making kinda of the same with the " KUBE "

I am curious to get opinion about this shape. I believe the short size will help the pumping a lot, but this is so wide for it's size. Just Curious here.
I shaped one very similar in concept and have been riding it for over a year.
It's a little longer at 5'0" but very similar overall. 28" wide, 6" thick has to be at least 120lt. Just straight chines and flat deck and light at 5ish kg.
For it's size it obviously doesn't have too much swing weigh. It is extremely efficient for light wind takeoffs. I'm on a smaller board atm and I have to pick my battles as far as gusts go. Some sessions I could've winged with a 6m I can't anymore.

Sorry i didn't address your question re pumping. It does pump fairly well. I've spent a lot of time on 4' prone boards so nothing really compares to that but it's better than the longer surf style shapes for sure. It turns fairly well.
One interesting thing.....it's wide, so I have to adopt a pronounced offset stance on it front foot a fair way to the heelside and back foot to the toeside. It lets me steer a bit further upwind when I'm toeside which is very useful for a non-switcher like me.
One last thing. It pretty much has a top speed when travelling upwind. It's a big frontal area and starts to get unpleasant over about 20kts wind speed when pointing into wind. I'm on a very different kind of shape atm with a pointy nose and it absolutely murders headwind by comparison. For light to medium though the loaf is a winner.

Gong has nine production Wing board lines: Hipe, Mob2Taste, Zuma, Lance, Flint, Mint, Lemon, Lethal, and the Kube.
Each with very specific behavior. The Kube is dedicated to freestyle moves by proving maximal performance for early take off and rotations.
Your board (5'0" and a flat hull) looks closer to the Flint, Mint, or the Lance than the Kube.

Nine production boards seems to be extensive. Hopefully, we are not going with Wingfoiling where Windsurfing went. To much gear and option which killed the sport.

I ride a 5'2 Naish Hover and recently an Indiana SUP Foil Pro 6'2/105l.
I notice the windage going upwind with the rectangular,longish Indiana.But the foil boxes are well placed(forward) and with a Takuma LOL i can get a very balanced centered ride (as KDmaui says).So it goes upwind better than it's predecessor,a 5'9 custom Wingboard with pointy nose but boxes a bit too far back.
I think that wingfoil shapers should forget about how windsurf/surfboards look when once on the plane,with almost half the board in front of the rider.
A Wingfoiling stance works more efficiently standing almost centered on the board.Less inertia,less windage up front.And tone down/loose the bevels,specially in the tail.
The Armstrong board proto that appears in some of the lates vids seems to be designed like this.
Even with a reverse bevel tail.

I really hope too. The gong line is a bit too much in my opinion. The board are really nice for sure but it lack a kind of simplicity here too many option.
To come back to the subject I never saw someone riding a board like their Kube. I like the idea of having a really really small board, but it's pretty hard to get feedbacks
Did you ride it Colas ?
No, I don't wing. No reliable wind above 13 knts where I live and no sheltered spots during storms,
plus after decades of WIndsurfing I am a bit overdosed on wind sports ;-)
Back to the Kube, from what I read, it sacrifices mostly the front section stability when on the water. so your starting technique must be good.
The Gong wing line is extensive, but so is their SUP and surf lines. We may see some streamlining of the number of models with the years, once the market stabilizes, as it has done with SUPs. There were twice as much SUP models in the Gong line some years ago.
Has anyone experimented with a board with a more forward stance like the Armstrong proto mentioned above?I am about to build a 6ft board which I originally designed as a 6'6" when I was chopping some length off the plan shape I chopped all 6 inches off the nose thinking having Less weight and wind age hanging out the front and leaving the extra out the back was a good thing.
I think the foil should be positioned so there's no, or minimum foot movement required from when you first get to you feet to when you're up on the foil (I don't use straps).
When you first climb on the board, you're in the middle so it floats evenly. You might lean back a little when taking off, then your back foot is roughly above the foil. If the foil box is placed so the front foil is a little behind the centre of floatation then you have to move your feet less. It will probably result in less foam hanging out the front as well.
I've got a short 91 L Smik which does this well. I learned on a bigger board which required running up and down the board to take off.
