I'm currently running an IQ foil on a Starboard Foil 147. My main sail is a Duotone E Pace 6.6m. I can foil comfortably from 15 knots. I'm thinking of investing in something around 7.8m with two cams as I feel like I still need quite a gust to get going. I weigh 68kg. Would I significantly extend my minimum wind speed with a sail like this? Please - no one tell me I need to learn how to pump!
I use an 8.0 non camed Aerotech Freespeed for 8-10 knots, switch over to 7.2 FS at 11+ knots, weigh 86 kg on an AFS W95 with F1080 wing for 8-10, using a Goya Bolt 135 80 cm wide.
Severne FoilGlide 7.0 is a great option for your size and setup, I find V2 with 3 cams 5 battens has slightly better top end than V1 but loses a tiny bit on bottom end
Both get my 95+kg flying from 12-14 knots with minimal pumping
I have the Starboard X145 with Severne Redwing foil. Invested in the Severne Foil Glide 2 8m and it's awesome for light winds. I'm 85kg and I'm foiling from 8kts.
I have the iQFoil that I use with a 135l freerace foilboard. I use a 6.7 two cam and a Flyer FR three cam. I sail in a lake (gusty) and I weigh 75 kg. The 8.5 needs much less wind to take off. I would get a foil dedicated sail for light winds (7.5 like you said) and yes, you will notice the difference.
you might get a little bit of overlap but that is not a bad thing.
I'm happy with my Phantom Iris X Mk2 8.0. It's very light in the hands and yet powerfull. Rotation is smooth when trimmed properly. Windrange for my 90 kg is som 10-18 knots, best from 12-16!
After thinking a little bit more, the overlap could be significant so you might end up using the new big sail and skip the 6.6 in favor of your next size down.

remember that your wide board is going to require more sail than a narrower board to get up, like my Goya Bolt 135 at 80 cm wide.
I'd say if you have an IQ Foil and wide foil board, if you want to go up and down wind and fast get a foil race sail. If you want to go reasonably quick, say cruise at 20 knots speed, get a freerace sail. If you just want to cruise around with the minimum of fuss at 15 knots speed in light winds, get a no cam sail.
Somehow your numbers sound odd. At your weight, 6.6 sail, large board and 15kn of wind you can be planning on fin already. With my 95kg I would be out there with 8.0 or using my 5.7 with a foil( +massiv front wing).
Do you have an issue getting up on the foil, or is your area that gusty, that you need the big sail to stay on foil?
I sail on a gusty estuary. Once up on the foil, I don't really have a problem staying foiling. Below 15 knots, I can't pop it up onto the foil with my 6.6.

I second the other post, with your 68kg + 6.6 you should be flying 9kn+ at least. 15 kn just don't sound right, I would check into your technique, move from IQ foil to something more user-friendly , at least until you dial in, become more efficient
I have all NP v8 sails from 5m to 8.5m that I picked up second hand. All the folks at my local are on the full iq setup with either the 8m or 9m HGO. Even the little 50kg women, and they get up in the real light winds. I thought I would go down that route, but the cost, the Raff to rig and the difficulty of up hauling that massive luff pocket put me off. I used my 8.5m for the first time the other day. Got up in super light breeze, but did feel a lot heavier and so much harder to gybe. It made me reflect that for a big light wind sail I would want something really light and easy to use. A friend had the 6m, 7m and 8m FoilGlide. In the end he sold the 7m as he found there was enough overlap between just the 6 and the 8. If I was looking for a big sail afresh the 8m FoilGlide would be my pick. If you haven't used big sails before, they feel pretty massive at first, and the FoilGlide is about as light as they come and really easy to use. Try for the FoilGlide 2, or the FGO (the reinforced Olympic version) as it has an extra camber and batten. You need a compatible mast tho. The space is a great sail, but I would say another sail in the 7.5 to 8m would be really good for you. I use my 7.7 more than any of my others sails. Only rig up or down if it is really breezy or super light.

6.6 to 7.8 is really too close, I think, for Foil use. I use a Sailworks Flyer FR 8.5 for light wind, and with clever tuning can jump from that straight to a 5.7 Revo wave sail once the wind reaches a steady 15-16 (I weigh 102kg).
I like the build quality of the Sailworks stuff, and it's also slightly less expensive than Severne for me, but if you have a good source for Severne the Foilglide is an excellent choice and I think the 8.0 would get you up in less than 10kt. It rigs on a 460RDM I think, which is another advantage over the Flyer FR, which needs SDM490.(If the 8.0 doesn't fly you, you really DO need to learn to pump!)
At what kind of windspeed could I expect to be overpowered on the Foil Glide 8m? Would the cams give more range in the higher wind speeds? I can carry my 6.6 up to about 20 knots. My next sail down is a 4.5.

You can foil with a 6.6 E-Pace in 20 knots when you weigh 68kg?
Earlier you said you sail on a gusty estuary. Are you quoting the speed of the gusts? eg average 15 knots gusting 20?
Where I sail in Poole Harbour UK its quite gusty. There are a couple of anemometers and I knock off 10% of what they read as they are on a pole on top of a hut on stilts/harbour wall, but I have a very good idea of wind strength as I can have a look after the session.
I sailed on 3rd Jan with a 6.5m, Ezzy Lion. I'm still learning and am 80kg. That was the first session I had 0 crashes and bettered my 500m speed. For me it was a decent session.
Garry has been foiling 3 years and is 100kg, he had 7.9m GA slalom sail. He is a decent speed sailor on fin.
Boris joined us on his IQ Foil gear, 8m IQ sail, he is 16 and about 62-65kg at a guess. I didnt see his board touch the water once, he foiled around every gybe. He has been runner up at junior & youth Techno Euro/World championships so very talented.
According to the anemometer it was averaging 14-16 knots, max gust 20, so I reckon averaging 12-14 max gust 18.
So to answer about when you will be overpowered with an 8m foil sail is anyone's guess.
Hey PK,
Not sure if I sail on the same gusty estuary as you?
I use a 7.7 Pryde V8 as my biggest sail @95kg gets me going in around 10knts, easy from 12knts and pretty good through the holes as well. Adj outhaul boom is a huge benefit for this size really helps with the range.
97% of my foiling is with a Flyer 7.0 and a S-I (or a Fringe) 5.0. I always use adjustable outhaul to broaden the range. This works for winds from 12 kts to 25 kts. Done. Two rigs and one board in the van. Don't need more most of the time. I have a Flyer 6.0, but I never need it, so it stays in the garage.
If it super light I plan to try my old NX2 9.0, but I will probably need a bigger board under it (my old L6). Most of the time, if it is super light, I go fishing.
That's the nice thing about foiling. You don't need a lot of gear to cover a broad range of wind speeds.

Segler, if you not wind foil racing, why not getting bigger front wing for foil?
I'm mainly riding on 1500cm2 now,
My range probably ~7-30kn on same foil set, wave sails 3.3-5m2. I have 2000cm2 on order trying to get 5kn.
Hopefully will have new custom foil board done within next month(Tillo) that 'should' also improve efficiency, power transfer.
I donated my race foil gear, including
My big 6.5 M2 sail to kids windsurfing academy in Miami... And usually ride without harness. Learning a lot watching wing group. We are so much more efficient but our gear and thinking is 2 years behind in tech.,etc

Hey Daithi. I've a suspicion you do and we met during a glorious sea breeze last Summer! Thanks for that. I might try an adjustable outhaul in the first instance. I've really felt the need for depth in the sail to get going and then a facility to flatten it off as the apparent goes forward so that would seem a good first port of call.
To answer miamiwindsurfe's question, yes, I do indeed ride a i76 in Florida. It is 1500 cm2. Easy to ride. I also have a AFS-2 1120 cm2 foil in Florida. I choose it when I want more speed. (Correction, it might actually have 1080 cm2, but you get the idea.)
At home my favorite wing, by far, is the Moses 950, which is 1350 cm2. When I want more speed, I go with the 940 (1100 cm2) or 720 (750 cm2).
Big wings are nice and easy riding. Most of us are not out to get max speed, but sometimes speed is your friend since it offers a big margin over stall on gusty days.
Segler, so you do ride with sails under 5.0? Guy in Cabarete rides on Moses 950 ? and loves it with smaller sails.
I like to experiment with foil design,
Gong Galaxy has huge selection, so l bought few front wing/stabs and got a local CNC shop to make me custom fuselage, I like relatively short but front wing forward.
I sometimes ride a 4.2 with my 950. On such days, however, I will tend to shift down to a 940 or 720.
A friend of mine rides a 2.8 over a i76.

Roughly, what's the fuse costing you?

Get your machinist to split the fuse front and use a big setscrew to expand it like the Starboard QL. I've built two fuselages using this design and it's brilliant.
Tempted to grab a Gong wing for windfoiling, the Starboard medium aspect wings are a little thick for my taste.

He charges $450 per fuselage, not sure what you describing...my custom carbon mast fits into it, it a bit longer and more forward, and works with Gong wings/stabs. I bought gong original fusilage so he had connection dimensions
$450?! I'm in the wrong business. Does that include anodizing?
Just look up the Starboard Quick Lock system and you'll see what I mean.

Anodizing included... Since I never had a chance to examine starboard's connection, i cannot comment for sure, but for my money simpler is always better in windsurfing design.
Things jam, break or corrode too
easy, plus Gong has long history/ high volume of sold foils that work well for me to mess with connection design.
As long as male parts milled correctly, it's all good.
The expending connection is less complex, compensates for wear and manufacturing inconsistency.
Also you might find NOT anodizing actually makes for a longer lasting fuselage. It's spreads the corrosion over a much larger area rather than concentrating it on a few scratches and the threading.
Stringy is making custom fuses in Vancouver Washington for ... I think $300? He is the one who machines the adapters for project Cedrus... I am having him make me a Windfoil length fuse for my Takuma Wings.....
