Hi all,

I am looking for a comparison between the 900 and 1000 wings in light wind. is the take off speed similar? what about gliding through lulls? I am not concerned too much about upwind ability or top speed, only about flying in light wind. I weigh 75 kilos and use a formula board with a fully cambered 8.2 sail as my biggest sail. Wind speed: 6 to 10 knots.

Thanks,

Willy

I forgot to add that I will consider to get a bigger foil dedicated sail if I need to.

If you're looking at SB foils, go with the bigger wing. I started with the GT, but like you (at 75Kg), I ended up with the 1100 Wing, 115cm fuse and 255 stab for light winds. Best setup for light winds... although they don't have that combo, you'd have to put it all together. Worth it!

Yeah, I wish I could buy a foil with the 1000 (race) or the 1100 (freeride) but unless I buy the team set, which I won't, I need to buy the extra wing as an add on.
I am seriously considering the youth iqfoil because it is the same as the senior (95 plus and 115 plus fuselages, 900 wing, and 255 stab) but with a 95 cm alu mast versus the super cool and expensive 95 cm carbon mast.
that is why I want to know if the 1000 wing would be much better for light wind than the 900. If there is not real big difference between them, instead of adding a 1000 wing I could buy a dedicated foil sail.

$B state that you can race iQfoil in 5 to 35 knots (but unlikely to race windward/leeward in < 10kns ).

Am the same weight and use a formula and SB race foil (900 / 115+ foil ) and often use a 8.3m sail. With a bit of pumping it will fly in ~8kns, but angles are not high/deep in light winds.

You could compare the lift of the 900 vs 1000 wings using the formula :
L = Cl * A * .5 * r * V^2
Or this handy calculator:
racerdirekt.com/hydrofoil.html

An 11% change in velocity provide much more lift than 11% increase in foil area.

If you aren't stuck on SB products there are other foils to look at for lighter conditions.

I have used SB 800, 900 and 1000 - I reckon noticeable but not massive differences in early lift, and glide through lulls - 1000 might be overkill at your weight and with only 8.2 as your big sail, I'm 90kg+ and still prefer the 900, feels tighter than 1000 - ideal if paired with 115+ fuselage so can change stab angle to get your extra power in light winds that way, I really notice differences between shims even though only 0.5 apart

Thank you, Peter. In what winds do you use the 900? What do you mean the 900 feels tighter?

take the 1200 wing from Zulu fins. this wing is suitable for a starboard

900 feels crisper to me, and stays controlled when wind picks up to 15++ (hence Olympic choice)

Why not forget about race foils, which are all about speed/angles - lots of less $$$ options out there with bigger front wing etc designed for max lift and min sail size in your light winds (sub 12)

In the lake where I do most of my sailing the people who get the most foil time in light wind are the ones with race foils, formula boards, and big high aspect ratio sails (9m and up).

In light winds, even with my infinity 84 and formula board, I prefer to have a big sail because it just works better, that is, more fly time. For example, some people might be with a 7 m sail and an infinity 76 (20 pounds lighter than me) and they might be foiling 60% of the time; in that same scenario, I prefer to use my 8.2 because I can foil more than them, maybe 75% of the time. Maybe they might have more fun while up because handling a smaller sail is definitely easier but when I talk about light, crappy wind, I just want to maximize foil time and get decent speed.

the other thing is when the wind is light, the water is totally flat so I don't see the benefit of a low aspect ratio foil to carve (or maybe I don't care about it in very light wind).

Lastly, the iqfoil youth with the 1000 wing (instead of the 900 wing) is 1700 US dollars with taxes and shipping included, and I don't think there are that many ultra light wind foils out there (with two fuselages) for that price; if I have warranty issues the windsurf store I would be buying it from is 3.5 hours away from my house (I don't need to deal with international shipments and weeks of wait), and if I decide I want something else I will not have a lot of issues selling it (same with slingshot, at least where I live).

I think my perfect quiver would be a performance kit for light winds where I can just point upwind and go places (with one sail if possible) and then a 105l wizard with an infinity 76 for windier days where I want a more playful kit.

Yep IQ + 1000 + 115 plus + 9.0 is fantastic light wind machine - maybe add 800 down the track for stronger breeze - and/or carving foil once there is swell to play on
Yesterday very light conditions so changed SB shim to 1.5 instead of default 2.0 - definitely more power and flying time

I haven't any experience with the 900 but I recently purchased a 1000 to go with my 800 (and 550) wings. The 1000 is noticeably slower and draggier than the 800 but fly's (and stays flying) in much less wind. I can feel my carbon mast flexing when under load on the 1000. It is definitely a much different feel but makes life in 7-12 kts much easier in my opinion. Flying gybes are easier due to the lower stall speed. ( I have the Team Set but mainly use it in 1000/330/95 fuse) (Im 80kg)

Anyone else tried the 1000 wing lately?

Hi there, I have both the 1000 and the 900, I did a test on the weekend for light air foiling. Started with the 900 and the wind dropped out to 8 to 9 kn so I changed to the 1000. I'm 95kg and was using A Severne HG2 9sqm sail, IQ foil mast, 115+ fuse with a standard 255 tail set at -1.5 degrees. I found it a lot more draggie and had to pump hard to get up on the foil but once up was able to fly fine. The wind dropped out further, 6 to 7kn. I changed the tail foil to the 330cm at -1 degree. Was still able to fly but was super draggie and I had to pump like a mad man to get on the foil. I was amazed at how slow I could stay on the foil, felt like I was at walking pace, was even to slow for my gps watch to kick into gear and tell me how slow I was going....
so after the Weekend, yes the 1000 works better than the 900 but only just and that's at my weight(95kg) so at your weight I wouldn't spend the extra money, go with the 900 ! And as Peter said the 1000 gets unstable at speed, at about 22kn it starts to flex the foil mast and gets unruly to sail....


just my 2 cents worth


waterbouy.

Agree with the comments above.
ive got the 1100,1000,900,and 800 set.
prefer the 900 wing over all the others ...as it seems a more do it all wing.
if I want to foil in lighter winds I'll jump on the supercruiser rather than jump up sail size
Im 85kg and hardly use my millennium wing now

did you try the super cruiser with larger front wing ?

No I've not felt the need to go larger.. I'm only on the standard 1700cm3 wing
