those fone boards are tiny and must be design for light weight and more advanced wingers.

That graphic doesn't make sense. There's no way that "Weight" + 40l comes up with a sensible number.

The rest of the site looks like they've done a cut and paste and included stuff from other boards. They talk about smart handles and decompression valves that don't appear to exist on the foil boards.

The beauty of the Metric system... 1 kg is about 1 liter of flotation, (or 1 dm3).
Yeah that's all clear as mud , so what you are seeing is the beginning of yet another type of foil board. These are basically fat prone boards for water starts using a wing ding. They basically stand on them submerged up to their waist and some how get up. Seen some guys start sitting on the bow of a boat like a sitting dock start. 
The reason for the handle in the bottom is so you can balance the foil with one hand and hold the wing in the other keeping it away from the foil tips and walk to the waters edge. For those that have tried walking to the waters edge carrying both will know what I am talking about. You really can't leave a foil wing on it's own on the beach it just blows away especially the Duotone with it's big fat leading edge , as soon as you put air in the Mofo it just wants to fly off.
I have come up with a method of leaving them both on the beach, or carrying them both without to much trouble, that works well especially when there is a fair bit of wind.
I place the board down with the foil facing into the wind, the wing upside down right behind the board with the leash passed under the board and attached to the fuselage as in this pic.
The wing is out of the wind and sits completely still even in 25 knots.
When I want to carry it I do it as I usually would just carrying the board i.e. the fuselage in one hand and the other through the wing handle and grip the board handle, if you know what I mean.

All good until you get to a narrow path or have to walk into 25 knots 
I have managed 25 knots for short distances no worries but as for narrow paths, I have only come across them walking to and from the beach, so I just carry the board down first and then the wing and vice versa on the way back.
That is a major part of learning though isn't it, dealing with the wing and the board both getting to the water and on the water and dealing with the 2 leashes.
The first couple of times is a nightmare.

Thanks tightlines. I will try the way you said. So far I am walking the board to shore then returning to carry my wing after I have unstrapped the wrist leash from a post at a park shelter nearby. But I have got a shoreline further away which a one way trip would save time. 
I do the same both at once as well but only short distance. Getting bit better now am going to drop down in wing size , see if I can still nail the starts . I'm maxing out at 28kph on the XL , should be able to go much faster.
Check out the prone start start then grabbing a wing , absolutely insane.

I think it makes perfect sense:
An 80 kg beginner needs 80+40=120 liters
The Rocket Wing's are all to small so he has to get a Rocket SUP: www.f-one.world/product/rocket-sup-pro/

Really

My 130l board is fine.

Yes, but the graphic only shows 50, 60 and 70l boards. The forumula is fine but it doesn't match the image.

thanks, I stand corrected
Here's a quick 1km from a DW'er today. Yes it's 3mins, but some may enjoy 
.
A put in some stats too for those that are interested.
Wind was a dying 15kn Southerly. You'll see my angles as I get close at time to direct DW. Still playing and learning. Having a blast though.
My second attempt at wing foiling with the duotone... up till I got the wing I've never managed to foil with any success so this is a big jump... Moses 873 foil underneath

Handle on the bottom of the board for my next custom
Dunno if you're making fun or serious ... but I saw that and had an "aha!" moment. The normal sup handle is nearly useless with a foil, this would be quite convenient. You'd gain a little friction while paddling, but once up on foil that resistance is a non issue. Hmm.
re: walking. I carry my sup foil with mast on my shoulder, with board along my back, wing facing down. As long as there's a little wind and I am walking upwind, I can reach a hand up over other shoulder and hold front handle of wing. Leading edge rests against board deck, wing floats behind it. But that's because most of my walking has been upwind thus far. 
Thanks for the video Abdillam,
I am not brave enough to show any of my learning, but I can see you and I are performing the same arial tricks so now I feel I am going toward better things.
Again thanks.

Serious and had same moment.
Here's another quick minute DW'ing toeside. The wind is super light, about 15kn (maybe less) and I am only on a 1400cm2 Foil. It's pretty cool how much fun the Wing makes the run.
Enjoy,
Ok, warning - this is a very long vid. It's a good 20mins from my session yesterday. Thought it might help some, share a bit and just share a super stoke session.
I'd already been out for and hour or so when I bumped into Sean Woolnough who's been learning for a few sessions or so, so it's also good too see how good his progression has been.
Anyway, sit back and enjoy ??
Thanks JB!
Watched it through. Good to watch the angle of travel in relation to the wind chop. I'd presume about 45 degrees to upwind is about best.
Good to see the footage of Sean going well too.
It shows what I could be in for when I take mine on the open lake. Decided more open water with an onshore wind should be best.
Unfortunately the surfs up at the moment so busy wave foiling. But can't wait to get the wingsurfer out.
Sometimes you just gotta ride, even when there's near no wind!
My tracker was calling 11kn, I think maybe in the gusts. Definitely not easy to get up, but timing and technique can do some amazing things.
I am only on a 1400cm2 foil too.

Nice going, definitely looks less than 10 knots
I guess with that big high aspect wing you'd go close paddling it up on the foil so you're not needing much lift from the windwing?

1400 is our small HA, we have an 1800. I usually foil with a 1650 or 2000. So relatively quite small.

So a shy friend is currently using a Naish XL with smaller rear stab for winging (and surfing 80% of the time), but has been looking at getting a 2000 wing to extend range of use and pumpability (Assume the 1650 is similar to the XL?). Would it be worth waiting for the 1800 HA, putting in the learning curve time to get used to a new wing that ultimately increases range of use speed etc? Can't help but think that ultimately the HA wings are going to be better for winging.
Getting more and more comfortable on the foil each day... progressed to a smaller lighter board and it all clicked...

This is an interesting one and there's no clear answer. The HA Foils while super efficient are quite a bit trickier to use. The 2000 is so easy and predictable. And yes the 1650 is the new version of the XL. The 2000 is super easy to pump and really stable particularly at slow speeds (over the 1800HA). Experienced riders that have the ability to stay on the foil longer and ride faster will get some performance benefits from the HA's, but if your more into cruising and are still coming off the foil often the Jet 1650 and 2000 are going to be a better suit.
Yesterday I rode in the ocean in a hectic southerly gusting well over 30kn. I was using the 1400HA and honesty think I would have preferred be on the 1650. You have to be more accurate and controlled with the HA foils, so when it's tricky conditions, it's another added thing on top of just keeping everything together.
As I said, there's no clear answer here. But just be honest with your ability and how you wish to ride. The HA wings are amazing, but do not over look how easy the Surf JET line are to use. Amazing amounts of performance at your fingertips.
I hope this helps a little. I don't want to talk either choice down, as they both excel in their fields. Just I think a lot of crew are looking into HA because it seems to be the in thing, but they really are a different ride.
Ride safe,
JB
