For more low end you from your stab you can do a couple of things:

1) a bigger but low drag stab. The way a stab works on take off is opposite to how it works in flight, because the angle of attack of the foil plane is pointing up as it rises up meaning the stab is helping generate lift, while in flight and flying level, it is producing downwards force in its role as a stabiliser (that is why the curved surface of a stab is on the bottom, the opposite to the main foil). A bigger stab just gives more surface area to generate lift (through angle of attack) but you don't want a chunky profile as that causes more drag, and you don't want more downwards/stabilising force. I would go for a big UCarve.

2) Shim the stab to make it flatter, so putting trailing edge down/leading edge up (so a wedge/washer on the rear screw of the stab for AFS) This is less drag, but more importantly generates more angle of attack as described in 1 and so generates more lift. The trade off is that it might give less stabilising support in flight, but should be ok if you swap to a bigger stab anyway. (Greg at Omen did a YT video on this a couple years ago, I think?)

If the foiling 'triangle of hardware' is power, board, and foil, can you get a bigger parawing if you don't want to change the foil or board? There seem to be plenty of second hand ones available at the moment which should help, but I reckon technique is a big part of the issue as well.

You friend got an extremely good low end set up. :)
I owned the V1 Super-k 92l so know that board quite well and demoed the Atlas 1130.
That combo almost takes of by itself and turn reasonably well but I found it also very slow.
The Enduro1300 has a similar take off speed, turns imo better and is faster.
When I put it in numbers I would say I can use KT 100-150cm2 smaller as some other brands while I need to pick AFS an 100-150 bigger for low end.
The top end is whole other game. I have ridden waves with the E1300 (wingfoil and Supfoil) over 37km p/h with full control and If you let go the numbers and just look at feel the 1300 is what you need: significant more low end and lower stall speed compared to your E1000.
Why not the 1100? I have the E900+1100+1300+1600 and think the 1300 covers 90% of the same range as the 1100 but with lower stall and take off speed. The 1100 work better when its more windy and the 1300 become a handfull, but ..you have already your 1000. If I would buy it again it would probably 1300-1000 instead of 1100.

UG stab:
I really like it for its glide and dragless feel once on foil, but if i get you right your issue is not with gliding but to get on foil, and in that regard that stab has no benefits imo.
Once on a foil its great. I just had an DW run with the wingfoil today (not yet into parawing) with my Pure HA1100 and replaced the HA stab for the UG41...whole different foil! The low end hasnt changed, but a lot better glide and pretty good turning and riding in the given conditions.
it also proves to me to not write off older foils.
I bought the E1100 last year and have the pure1100 now 3years and altough i really wanted to like the newer enduro, the older pure HA simply suits me better.
similar low end but more slippry through the water and better acceleration+speed+glide.
The E1100 turns better and has a slightly lower stall but with the pure its really easy to stay at speed that that isnt an issue. I guess the Ultra,s are more similar to it.

HA stab,s:
First get the 1300 and see how you like it with the HA40. For me that set up works as well altough I mostly use it with an HA43 to have just that extra bit to push against..but the differences are small between the 40 and 43.
This also a situation where I already have it, but If I would do it over again I would probably go for the biggest carve as i,m quite impressed by the U-carve140 with my Enduro900.










Thanks Jeroensurf and yes I agree my friend's kit was super stable and easy. But as you say the KT 1130 is quite slow. My friend compared it to jumping into a race car when he tried the enduro (with a wing) I was visiting him in Estonia and we had a fun session on Lake Peipsi (Raapina) with view of Russia on other side..



After some thought I think I will go with your recommendation of the e1300 and ha40. You are right the numbers look large on paper but it makes sense for AfS.

Thanks for the tips, hope to report back in a few weeks time!

Damien LeRoy and Gwen reviewed Atlas 680 and E700 together, and said Atlas was more comfortable at lower speeds and Enduro at higher speed, though measured low and high speeds were very similar. At end he comments on the larger sizes.

Back to the stabs...
I have now a couple of sessions with the U-Carve140 and the Enduro900 (short fuse) and Silk1050.
We had a run of NE wind that means mainly waist high wind kinda bumps/swell that are not really breaking, but fun to make some turns on and try to connect things.
A thing that suprrised me a bit is that I need to move the mast 2.5cm forward for the same lift feel as with my other stabs.
Compared to the U Glide:
I liked the U-glide41 with the Enduro900, but the Ucarve 140 doenst seem to give up a lot to the Uglide41 on glide while it turns a lot better in bumps.
think the Uglide is slightly faster, but I dot really care about speed suits me and overall I think the carve suit my conditions most of the time better.
Compared to the Silk 152/142stabs and Kparts Mako V2:
I Think its better than the older Silk142 and 152 in every performance aspect, glide, turning and drag. That said, those old Silk stabs slow things down a biyt and are really pitch stable so you can push hard against them in surf. So they still have there place for me in chaotic conditions.
Kparts Mako V2 140: The U carve turns almost as good with better glide and more pitch stable. ( being more pitch stability then the Mako V2 isnt really an big effort, because imo it lacked that).

Anyone try the Ucarve 140 against the pure 145 stab? I love the pure 145 with the silks and enduros. Actually picked up a Ucarve 140, but havent had the chance to ride it yet and curious if others have a first impression. I'll report back once I'm on it.

This was the summary of testing I did a few weeks ago trying to find a stab I liked for the Pure 700, which is my main winging foil. I don't wing very often, as I parawing and downwind way more (which I use the UG41), and have been using the HA38 with the P700 but it wasn't a good fit for me.

"Pure 700 + HA38 in forward position - good glide, but turning a bit sticky. Quite loose in pitch in the pump, which is not good or bad.

UG41 in rear position - excellent glide and speed, which the 700 liked, pump was much more solid and projection was very good. Turning about the same as the HA38 but carried more speed through turns which was great in the bumps. Kept up very well with the bumps.

Pure 150 - more bottom end and great control, especially through the turns and in upwind through the bumps. Really fun in the flat as I could really push hard through turns, with confidence, and wasn't worried about slow exits as I could rely on the stab for support. Glide was its downfall. While turning in bumps was great, it didn't really keep up.

Silk 142 - my favourite of the test. Per the 150 but better all round, except low end and the control going upwind through bumps where the bigger 150 edged it. Super fun in the flat, allowed such tight turns with great control and confidence. Glide wasn't great, but only noticeable trying to ride bumps.

UC130 - it was good, but wasn't different enough from the UG41 to really stand apart. I tried it in the forward position first but was a bit too pitchy and was better in the rear. Confirmed my thoughts that I'm looking for a lower AR stab for winging which is primarily a flat water thing for me. If I want bump riding, I'm on the parawing/DW.

Where does this leave me? I think a USurf is going to be the ticket, lower AR than HA38 but lower drag vs the old Silk stab. I can't remember why I had discounted the UG41/preferred the HA38, but I think it's the size of chop I get locally which is big enough to cause instability on the foil, but too small and short to actually pick my way through. Using the slower HA38 stab probably helped as well. The bumps today were much bigger / ridable so kinder to the UG41."
