The screw labelling are a handy touch... that saves some hassle and referring to bits of paper.

SF Series is officially up on the website and video on Youtube:

Chord:
- centre, next to fuse: 13 cm
- 20 cm from the tip: 10 cm


Thickness:
- centre: 13 mm

- 20 from tip: 10 mm


My measuring tools aren't super professional. Hope it helps!

Are you sure with 13mm thickness of the 1050 HA in the Center?
My 950HA has around 15mm there.......which is still very thin for that size

No, not sure. As I said my tools weren't super good. My thicknesses measuring tool was too short to reach the thickest section of the wing. I'll remeasure.

Got my first run on the 1250HA yesterday. Miscommunication w my dealer, but showed up w the 270 Stab. Was way powered on a Mode 5.5, probably should of been on a 4M. Waves thigh to waist.
First impressions. It's passive speed is very fast for a 1250. It does take more speed to come up, but thats typical for faster foilers. It tracks like it's on rails and that includes the jibes. On the downwind waves and wind chop it glides and glides, at speed. Was actually surprised by the turning ability on the waves. I experimented w different pumping cadence and depth. TBD.
I forgot to put the pedal down to get an idea of top speed. But lots of 18 mph/15.6 knot peaks.
I'll make a point next session.
I've got the 208 Stab coming so more after I run on that setup.
One big question, I really wanted to jump it. But decided not to until I checked the North site. Didn't know if it had the same restrictions as the Axis ART? I couldn't find anything online?

Sounds encouraging! Shlogger, what's your weight? And what board?

I moved to a north MA1350 set up with the 600 carbon fuse from a Sab set up a couple of months ago and love it! One tool for everything, super solid connections and I really like the feel. Will be adding smaller wings from either the HA or new surf wings at some point soon but love that it's all so modular and the build quality really is top notch.

Hi Kovert, what Sabfoil did you come from? What is your weight? What board? What wing size do you use with the MA1350?

Thank you

Hi!

Anyone with experience using the bigger HA 1250/1450 new and older versions? With the lower aspect of the older wings do you think
it will get on foil earlier than the new ha? Have slower stall speed?

Looking for a light wind setup, prefer earlier lift than speed but likes good glide.

Thanks

Oskarhhh the below IG chat is from Jan 2022 when I approached a North development rider for his views on the previous 1250 and 1450. Feel free to guess who








I had Mackiteboarding backing up the above.
You got to remember that the initial Sonar was born from a collab with Delta Foils. The DF designer had his own ideas on stabs (hence the s01).. luckily North revisited the stab as a first step upgrade. I can imagine this 1450 could be interesting especially because of its lower price atm

Second run on 1250HA New today, this time w the 208 stab. Used my 5.5 Mode in 15-18G20.
Once again top speeds were around 18 mph/15.6 knots.
Jumped it quite a bit and it jumps nicely and recovers pretty easy.
Spent a lot of time tacking and jibing and you do need to keep it smooth and fast.
You do need to get some speed up to come up on foil. Pretty easy, but this foil is not your light wind wing answer. I thought it might replace my glider but a few weeks ago when I unpacked it..it's foil section is thin and I knew that wouldn't be the case.
Best feature IMO is the glide. It's like knife through butter. I see this being my downwind winging foil.
It pumps fairly well. With the 208 stab, it likes quick flick pumps. I did slow it down and go for deep pumps in flat water and it will respond. But no way this will be my dock start foil.
It's fast and glides unreal pound for pound.
I'll be waiting on the Surf foils which sound like they'll be my niche. I hear a dedicated pump foil is coming out soon.

For me with 86kg the 1250HA is the perfect Light Wind foil. In the meanwhile i have tested this a few times in comparison with notorious "light Wind Experts" at my Spot, which are lighter in weight and have much bigger frontwings. But you need to be familiar with the right technique for this kind of foils. It is not difficult and even less effort once dialled in. But when you come from a foil like for example the Naish HA 1800 (or 2140) you will not see the light Wind Potential of the north1250 at first without changing the technique. But once dialled in you get to fly earlier and have much more apparent wind in the lulls due to more effortless speed

Agreed.coming up on foil technique is def different, just like most other thin fast foil shapes.

Almost forgot...really liked the 208 Stab. It'll be my go too.

Any reviews out there on the SF foils yet?

My local shop is saying these will be available at the end of April

2nd session last Sunday with the 1050HA , s270, full carbon setup. While the first session was a bit overwhelming with new wing, foil, different spot and not being able to feel everything, this session was more about feeling the foil.
Prior I set up the mast 1 cm aft, installed front footstraps just to aide my take offs (compared to strapless)

The foil worked great:

- taking off with 6m and 4.2m was pretty good. Just not too much AoA is needed. Make the speed first, keep the board nice and flat steady (footstrap helps) and the lift gradually builds and as it does just keep steady. Little AoA. I made the constant mistake during my first session to take off with bigger AoA and the super thin and narrow chord wings easily stall.. resulting in 'dolphining'. I guess this applies to all 10 AR high aspect wings.

- it instantly accelerates to higher speeds. You literally feel every chop you foil through. I guess the stiff mast translates a direct feel. The mast is stiff. Much more towards my super stiff AFS windfoil.

- for now I am really happy with the 700 fuse and the 270 stab. It doesn't feel like a big stab. Big enough for stable riding, small enough for allowing easy mini pumps.

- glide.. the downwind glide is a very exciting part of this foil. I havent yet explored because it's all new but going downwind immediately being able to stand up more straigth right above the front wing centre of lift felt good. Again the carbon mast translates every little bump or chop into the legs.. great feeling!

- I am still getting used to or discovering the parameters of the foil like stall speed. It feels like a foil that asks you to keep speed going otherwise it loses lift..coming from more thicker, mid aspect 1700 cm2 wings this is new territory.

- I also managed my first jibes and see here too that keeping the speed is important.

Doubts or concerns: I haven't tried but unsure this is a light wind beast for 10kts winds. But that's for another day to try out.

Overall superstoked to learn more about this foil with each session and happy with my choice for North.

One question I do have for others: what is the North Sonar go to frontwing for uber light wind sessions? Would that be a bigger size HA wing, or SF or MA wing? What front wing do the team riders ride on with the North Nova Light?

a friend of mine who also has the HA1050 would recommend an HA for lighter wind.

in his words:
It's more efficient and has more glide.

for me, he said the HA1150 would be enough for light wind.

I can imagine that being the case! What's your weight WST?
