Hello,

I recently bought a F1 select foil. The carbon version 90 cm fuselage, 60-80 kg version. My weight is 70 kg.
I've put it under my Ftype 138 and it goes very well when there is a little more wind and a 7 m2 sail.

But I wanted to go low wind also ( as much foil days as possible). I saw a video on youtube that a wider board gets you going faster.
So I bought a formula F2FX year 2008 with the airpipes. But it's not possible to foil in light wind. The board stick to the water.

What can I do ?

I think pumping technique helps the most for light wind foiling, pumping both the sail and the foil.

Hey JoSpeed I use this board for a couple of years foiling and I'm 112kg it will definitely work for you in the light breeze but a foil board is better as it's designed for it Happy Days!

You did not say what size wing you chose. Select offers 769, 866, and 1050 cm2 wings. Their wings have a very high aspect ratio. Excellent for speed, but quite touchy when flying slowly.

For windfoiling, the board size and shape matter only for overall float for uphauling and turning when not in flight. When in flight, the board is just a platform to stand on. Also, we have to remember that even when you are slogging forward at sub-flight speeds, the wing is already lifting. This makes the board light and easy to pump to go faster and begin flight. My old formula board has a LOT of nose rocker that makes it very difficult to pump with a fin. With the foil lifting from below, it is easy to pump.

If you are looking to improve light wind foiling, your first issue to solve is the surface area of your wing. After that, you solve sail size. After that, you solve board size and shape. In that order.

thanks for the replies. Select works with weight categories. If you are 60-80 kg you should take the 750mm2 wing. If you are between 80 and 110 kg you must take the 850 cm2 wing.

So it wasn't in my mind to take a bigger wing. For their specifications I could go flying from 7 knots with this foil.

Is a longer fuselage not an option?

Maybe that formula board is to big for me ?

Hello,
I know the starter of this topic, we foil at the same lake here in belgium.

I also sail a 90 cm wide jp lightwind board
with foil but my fuselage is 115cm. Front wing 800 . I think that a longer fuselage would be for him also the solution for earlyer flights below 10kn of wind.
Longer fuselage gives more lift and stability, at least thats what i figured out from different sources like a specialised shop in holland, groups like windfoil new zealand and others.

I dont have so much expierince with foiling but it works for me really good, i lift in 8kn wind.

Our weight is not so much different.



Thanks

I am a beginner foiler. I weigh 75 kilos and use a formula board, low aspect ratio foil (slingshot infinity 84) and 8.2 full cambered sail for light wind. I am still learning how to pump to get flying but reality is I will not be able to foil as early as a semi-pro or pro sailor.
You want to have your mast base as far as possible. some foilers that sail with me in very light wind use formula boards with starboard 1000 wing and high aspect ratio sails around 9-9.5 (they weigh around 70-75 kilos). What I am saying with this is that you might need a bigger wing and bigger sail. I do t know much about your board but unless is a horrible design (I don't t think so) you board should be fine for light wind

I just checked the select website and next to the 1000 wing and next to "for riders between 80 and 115 kg" it says in all caps and red font "ultra light wind". I am pretty sure they mean ultra light wind regardless of your weight (of course, unless you are an extremely light person!)

Those recs look obsolete, honestly, or depend on big sails. Guys our size easily use 850-900s for racing (IQFoil for example) with 9.0s and for freeriding 11-1500 or more. I use 1000-1100 freerace wings without a problem.

Can you fly in 7 knots with this foil? Probably. Can you get foiling in 7 knots with this wing? That's a lot harder and takes really good pumping skills and a bigger sail than a 7.

Edit: I should add that a few years back, Horue said their XLW (979cm2) was a big guy wing. I ordered it anyway. Made a big difference at the low end vs their 779. Now it's really described as just a light air wing and since they've come out with a 1300cm2 XXLW.

I used a gun sails 8.6m GSR 2016 model but that RIG is heavy.

Wide boards, lightweights step down on rear strap in quick, successive pumps to release the drag.
Setup changes required.

I think this true, on french forum I found a guy who put the 1000 cm2 wing his foil. His weight is 74 kg. He can foil with a 7 meter on sub 10 knots. Those specs are indeed obselete. The manual says with the 1000cm2 wing only use with 1060cm fuselage. ? Marketing ?
Do I have to change my stabilzer also then ? Or also marketing ?

No doubt. That's why spoil specific sails tend to have thinner film, less battens, shorter boom lengths - the structure of large slalom sails is pretty heavy. Plus, there's a certain size where you can pump less effectively. For me, again I'm around your weight, I don't get out of the water faster with bigger than an 8 because I can't pump a big sail as effectively. OTOH, once that Gun is moving, it will go through lulls much better than your 7.

It would be a lot easier just to use a larger wing, however. Even companies as focused on speed as Phantom and Loke offer 1000+ wings on their freeride gear with no mention of rider weight. Starboard has the Supercruiser, Moses the Vento 790, Slingshot the i76, Pryde Glide series. These are all freeride 1500+ wings which are easily used by lighter riders, too.

If you want to chase the low end, you'll need either more lift, sail power or both. The width of the board starts to become secondary once you get past 80 or so cm.

There's absolutely nothing wrong with your kit in general. It'll be a lot of fun to ride. Just know that it will take a bit more wind than a larger wing to get going.

Edit:
"GUNSAILS vector 7.8 + LOKEFOIL lk1 1000+JP australia 135"
A bit more sail, a bit more wing on an 85cm board

Your board is too big for your sail. I'm 93Kg, so not really the same, but with 900 wing and 7.0 I can fly in 7-8 knots with a 85 wide JP135 foilboard. With the formula and 7.0, everything else the same, I need at least 11 knots because the kit is not balanced (and with a 4.6 and 70 wide foilboard, same 900 foil I fly in 11 knots of wind aswell because that kit is balanced!). A formula should be used with 9.0 minimum if you want to unlock the boards light wind potential. If you ride smaller as a biggest sail you should ideally use a smaller board. Ofcourse other things like ease of uphauling and budget come into play so its a decision you must make yourself. I'd recommend a smaller board if the sole criteria was early planing with a 7.0.

This is because exactly as you say, the board sticks / drags. A bigger board sticks / drags more than a smaller board, thats why most recent foilboards get massive cutouts, but also why a bigger board just plain needs a bigger sail to get going. There is more drag and therefore more power is needed to unstick the board.

Wings are interchangable, and not (solely) dependent on your weight, you should be able to use a 900 or 1000 wing, just in less wind than I (93Kg remember?) would. Maybe they recommend those sizes as average size or something like that?

For now I'd say try the 1000 wing, if that doesnt do it for you, exchange your board for a smaller one.

I don't think the F1 is compatible with the F2

Sorry carry on

This aritcle says : choose that wing... Okay I choose a bigger wing the 1000cm2. The Select manual says : change my fuselage to a 1060 and another stabilisator ?
Is it nessacary to buy a longer fuselage and other stab. ?

In general you will notice that a longer fuselage works with a smaller stab. That's because there is a longer moment arm, so a smaller stab can still do its job. People who have tried the Starboard 330 stab with the 115cm fuselage find it impossible, so they go back to the 255 stab. The 330 is for the shorter fuselage.

You probably need to talk to them directly. You can go to a bigger wing and use the same stab (the starboard freeride actually uses a bigger stab for the 1100 wing than the 800 on the GT). You can go to a longer fuse and use the same stab or just shim the stab - depending on the design. A lot of stabs for shorter fuses were set at higher angles and you can use the same stab by shimming it to have less angle. That's how a few people have used the bigger 330 stab on the longer Starboard fuses.

I briefly owned the alu GT and, iirc, the 330 stab has a pretty high angle. Higher angles are slower but inherently more stable. It is quite stable for a short fuse foil. However, sticking that stab on a fuse 40cm longer makes it too lifty. The GT-R which has a 95cm fuse (20cm longer) uses the same 330 stab as the GT which confirms the experience of a lot of people who bought a 95cm fuse for their GT and it worked fine. So - it's going to depend and is it optimal vs will it work. It may also be that the larger wing is typically used for upwind/downwind racing where the longer fuse is much more necessary (especially upwind). For reaching, shorter fuses work well and are actually preferred by many and smaller wings are more the norm.

Are there any persons who have select hdyro foils on the forum here ?
