Have worked out that my modified sailboard to windfoil board is not balanced enough in its volume distribution.
to get up standing I'm too far forward and getting back to near foiling position sinks tail and thus drags it so much as to resist getting any speed to get foiling.
if I was a light weight bastard it would be less an issue but at close to 100kg in wet wettie.
so suggestions on board size and volume and dimensions would be much appreciated.
plus bottom handles???
I'm also 100 kgs and I find my Naish Hover 125 ltr board perfect.. It's 6'4"x 31".. and has a bottom handle.. 
this 6'5 has also been a good go to board for the 100kg guys

In stock and ready to go.
Or you could look at doing a Custom Sized option?
One of the things that determines the answer to your question is whether you can already wing foil well, or whether you are learning, because these result in two different answers to your question.
For my own experience at 95kg, I actually started with the One 6'5" x 29" 130 litre recessed deck board that Angie recommends in her reply, and found it very difficult as a first board, particularly in winter conditions, windy, gusty and choppy. The problem was not the volume, but the width and heavy bevels on the rails. The result was a board that was relatively unstable, making it difficult to even get to my feet when it was choppy. After 3 or 4 sessions making very little progress, I relented and bought a Smik 6'9" x 32" 143 litre, and the difference was immediate, stable but still quite short and light.
I'm now up and foiling fine and will probably go back to the smaller One board soon, and I'm sure it will be good. But my point is that the board you need to learn on without struggling and getting discouraged is different from the board you will be riding after 20 sessions.

Yeah always hard right at the start for most people as the board to learn on really is not the one you will be riding 10 or 20 sessions in so most people either put up with the learning side at the start or get a bigger board and then just down grade but this can be expensive(unless you live on the gold coast)
Also can depend alot on ones own previous experience as someone who rides shorter SUP's more than likely will pick it up quicker than say some one who just surfs as the SUP guy already has that paddle knowledge so only really has to adjust to paddling the shorter style foil boards. My guess is you will be feeling the extra width as going to 32 wide over 29 in foilboards is a huge difference as it is in any kind off SUP as well. We made a few 6'5 x 31 for some guys that are well over 110kg one guy was 130kg just for that reason and the boards have the same rails as the 29 wide and for them now its like standing on a dry land. Down side is all that width does push water and never feels as nice when up on the foil so always pro's and con's but extra width is better than extra length.
I must say though we have plenty of big over 100kg crew using the 6'5 and lots in the 90kg range using the 5'10 but as i said its more got to do with the experience of the rider coming into it these days and also how many boards they want to buy.
It sounds like RAL IIN is mostly going to use it for wind winging so going smaller should not be a issue as most crew start on there knees to build up speed and then jump to there feet allowing a smaller board to be used. If in the surf then most of the time the water should be glassy as foiling windy waves paddling in sucks and is hard on anything, well it is for me
If doing a paddle DW then it's only 3 to 8 good paddle stokes and then if all goes well that's all you need to do, haha sounds easy
We have big easy learning boards here on the gold coast that we just lend to people for the first few weeks and in 99% of cases after two weeks they bring it back and pick up the board that's perfect for them which saves the whole buying two board thing, more than happy to lend it to anyone if they pay the shipping both ways!!

I agree entirely, and don't think I'm being critical of your board, because I'm not. I think it will be a good board for me now that I have some more sessions under my belt. But starting off on it, particularly in crappy winter conditions, was harder than I expected. For that a big stable board was great.
That's the paradox of winging, and I guess a lot of other watersports as well, you outgrow the gear you need for the novice phase pretty quickly. Your approach of having some learner boards for people to get started on is a good one, will result in a lot more happy customers.
So I'm a beginner at Wingfoil but on the odd occasion I fluke getting to my feet and get some speed with feet in position to foil. The foiling part is fine till I try to turn then a crash leads to ages of trying for another fluke.
plus I need to strengthen legs to get from knees to stand. After a couple of attempts the leg muscles are jelly.

I fully understand your pain.
I am 75kg with 74yo legs so jelly is a good description.
I have the Naish 110l and 125l. If I am at my best the 110l is ok to go from kneeling but when a bit tied or an off day the 125l is easy to getup from kneeling. So a bigger board makes getting up from kneeling much easier for me.
The new Naish boards with handle in the bottom are fantastic for me, no issues with swing weight due to the design.
Im 105kg and learned on a 142 litre board. Its long and stable and gets up to speed easy and fast. That put a lot less strain through my legs and sort of helped with and technique.
Ive now gone to a 135 litre 180 cm board which floats well but is a new level of skill to get foiling. Once up its great but unless its windy its hard work.
A friend of mine learned on the same 142 board and he is only 75kgs. He progressed just as quickly but had a smaller wing to start out.
Make it easy and don't rush to go too small too early
I'm 112kgs and up to mid 20s in seshes and on a 7ft2 board at 173 litres and found it great to start with and are quite happy for a while yet learning in winter in 30kts has been great fun I don't feel rushed to down size but will do eventually

I'm 225 lbs I started out winging on 6'8"145L Kalama supfoil board excellent supfoil board but for winging soon realized that was bit large and heavy for winging now riding a 125L 5'8"X29"custom and it's night and day better for winging lighter less swing weight don't waste your time on large heavy boards make your learning curve easier more enjoyable with a lighter smaller board much easier for winging but with our weight I'd try to keep it no less than 120L for easier knee starts and especially for learning,as stated your learning curve will have a lot to do with previous foiling experience kite foiling or supfoiling experience make it much easier to get the hang of winging.A handle on bottom is mandatory if you wing in a surfy windy location
Possibly, short of acquiring another board, you might install a forward fin box so you can slog and foil from almost the same position.
Twin track cassettes cost $100 and are easy to install with a router.
Tuttle cassettes are slightly cheaper, but more steps for installation.
At old ages with weaker legs, we won't be pumping like the kids. So, we might need longer boards or floatier boards.
Just because Kai rips with a 4'9" wingboard, doesn't mean we can.
Thank guys
I'm going to bash up my own and it looks like with your advice it's to be about
125-130L 1900mm long and 750mm wide.
with a bottom handle and even a top as I use my Spitfire XXLW foil so often carry my Windfoil setup by one hand on fuselage and the other by mast base.
Also my Zeeko Yipsilon wings are quite stable just floating on leash which helps.

Respectfully disagree
I'm 6zero 225 dry ain't the youngest winger out there,but old enough to know that at our weight class if you want to learn winging easier faster,and more enjoyable get yourself a smaller chunk of foam board min 125L say 6'0" with handle top and bottom good enough for learning knee starts and you will be up on foil much easier quicker=more fun on a smaller board winging wise,also a big wing underwater a Axis 1020 or equivalent for learning is optimum for us big guys lighter faster stronger less swing weight it's a more fun recipe for success for a HW rider
Something along these lines

What is your board's width and thickness?

5'8"X29X4"7/8 ish had my doubts I could ride a board that small being 225lbs but for winging was pleasantly surprised how well it worked for a big guy,admit it be tough to supfoil on for me,however never tried it yet,but winging and supfoiling a little different tools needed for the job for sure
Initially its all about getting from ones knees and developing techniques to back up issues.
Once this is achieved having fun up on the foil is not a big deal until one tries to jybe.
While I can toe side kite foiling I having issues wingfoiling.
Help
These winging boards look intriguing especially the 6'0" or 5'8" for us HW riders food for thought.nice looking big guy board tempting,hmmm

Yes drifted looks good. I will have 105kg on mine plus wetsuit etc so probably just buoyant. Could be hard work

Hilly you not have any issues readng your progress.
My friend, BT, is a few kgs more than you and everyday board is the Naish 110l or if he is highly motivated its his 95l.
. Scotty says it will be a while
