What's the wind range of the 85 with f800 and f700 for a 80 kg begginer?
What's the best foil dedicated board size for this foil?{]
Is it possible successfully matching it with the S or R wings model?

Wind range depends on sail size as well. I'm pretty sure the AFS 85 can be handled in very high winds, too.
I'm about 85 kilos, too and seem to get on the plane with the F800 in about 10 knots and a 6,4 sail. Guessing is diffcult for me, though. I was out on the same combo a couple of days ago with the wind picking up and finally gusting to 30 knots (not my estimate, but there is a webcam with a windgauge at the beach). It was very challenging and not relaxed. I would have been overpowered on the fin board as well and I surely didn't look good, but was positively surprised that it was still somehow sailable. I couldn't sheet in in the gusts, but with the mast foot set a little further forward than usual (130 from the tail) holding the foil down was possible at least. It's a very controllable foil.
The F700A takes about 3 knots more for take-off, but can probably handle a lot more wind.

Almost every foiler here in Berkeley Ca. hits sealife while foiling at least a couple times a week. BAD....!
I try to weave if I see anything, and also attach a loose 3mm leash from rear footstrap to foil mast so the vibration and the continuous "whisshing" sound might indicate my location and direction to intelligent sea life.
Foils are pretty silent, and sometimes fellow foilers mention they can hear my setup as they pass. GOOD....!

So I presume your shims INCREASE the stab down angle, correct?

Reason I ask is that the Moses Race and Starboard Race shims are designed to DECREASE the stab down angle.

segler said..
Current I use zero shims for the F700, and one shim for the F800.

The shim is made from coke bottle plastic in a drawing that Sailworks issued. Yes, the shim adds thickness to the front of the stab, which, being mounted underneat (same as the main wing), increases down angle.

Rather than measure the thickness of the shim, I just measure the change in the stab down angle. The shim adds 0.5 deg down angle.

Hey Sandman

The new AFS 95cm (94cm Fuselage) Mast is only compatible with S&R wings (confirmed by Bruno), which means if you want to go with AFS foils and use F wings then either you get the old 95cm Mast (88 fuselage) or go with what their configurator only allows you to do and get the 85cm Mast.
Any thoughts on this?
Foil Newbie researching gear.

Not on the new 95 with longer fuselage'

Think your right, something is lost in translation. I prefer your version though as would prefer to get the 95cm mast which would give me more scope for progression with diff wings.....if I progress of course.

If you here otherwise let me know.
Thanks.

Well Bruno designed the new 95 cm T-bar. Sent him an email, will let you know what he says.

I agree, if I were you I would get the 95 cm T-bar too, looks cool to boot! Though while starting out I would stick with the F1080 wing, the S-series wings would probably be my choice now.

So the AFS stab. shims are really important for light wind foiling, but now that I have an F800 (now F1080) and F700 (now F770) I am testing out shims on the F700 too.

For the F800:
1 shim for under 15 knots, 2 shims for 10 and under.

For the F700:
1 shim for 15-18 knots, and since I start using the F700 in 15 I do not think 2 shims would help me. Also Need 1 shim in 18-22 and a detuned sail (see below) otherwise a gust will make the foil jump out of the water.

According to Bruno the F770 wing is suitable for the new 95 cm mast, but the F1080 wing is not suitable, does not mean it will not fit, sounds like it may just not perform as intended. If I was using the F1080 wing on the new 95 cm mast I would likely use a 280 rear wing since with the longer 94.5 cm fuselage the rear wing will have more leverage. But mixing/matching foils is touchy, and that may be why Bruno does not recommend using the F1080 wing on the new 95 cm mast.

Here is a review of the foils that I did
AFS Wind FoilsI have been using AFS wind foils for some years now so I thought I would give you my impressions of the latest 2021 versions. I used to use a W105 foil with the R1000 wings and that has been replaced like for like. The R1000 wing has been renamed R810 as the wings are now named by their surface area rather than their wingspan. The new wings will fit on older fuselages but the 2020 wings will not not on the wider 2021 fuselages (apart from on the w85 which is unchanged). The new flange at the top of the mast is now built in and much stronger. The graphics are built in which again is an improvement.So would I notice any difference with the new foils claiming to be stiffer? Yes, there is a difference but you won't start flying and say "wow this feels a lot stiffer" what I found is that with the older foils there must have been some increased flex that gave you a sense of height ie you were aware when flying at near full height but at first on the new foils I often found myself flying at full mast height without realising it. The flight feels the same whether you are 10cm or 100 cm above the water. The new fuselages are a few cm longer and if you thought the old foils gave a very level flight the new ones do even more so. I don't race so I can't comment on comparative upwind ability etc but will say I can point as high as I wish. I had the old W95 which was used mainly in stronger winds on narrower boards with a f800 wing. This has been replaced by the new W95 with either the R810 or R660 wings. The F800 (now renamed the F1080) is not available for the W95 or W105 so I was at a bit of a loss with what to replace it with. I was slightly nervous that the R610 would be tiny and would be a very on/off type foil making life hard work in the gusty winds I often go out in but it is working well. I use the R810 with sails down to 5.3 and winds up to maybe a 25 kt gust. And then the R610 for the 5.3 and below and if the wind is over 20 kts. Even with its small surface area the R610 keeps going through lulls and round gybes etc (i am 95kg). The new foils come with shims. They have a shim for the front wing in case you find your board flies very nose up or down and then a second shim for the rear wing for you to increase or decrease lift. I am pleased to say I have not used the shims and the foils retain that "plug and play" nature of the older AFS foils, no need to go messing about with settings. I have used the R810 race wings for a couple of years now, despite their name they are very easy to use. They feel slippy and efficient through the water. To get flying they accelerate easily and don't need much in the way of pumping downwards. You are best to concentrate on building speed through pumping the sail. When it is windy there is no need to pump at all and you can use the nearest bit of chop as a take off ramp. When the wind drops very light you can keep flying by pumping the sail, small high frequency pumps working the best. The only down side I can think of for using the race wings for learning is that they are very fine tipped so you don't want to run it aground or kick it. The wings are very tough but with such a good product it deserves to be looked after.I should point out that while the wings have a "race" label you don't have to sail them from a outboard stance, the wings are very well mannered and can be sailed in a relaxed upright style with your back foot on top of the front foil bolt, in fact that is how I use them most of the time.So in conclusion I am very happy with the new foils. I thought I would have to move my footstrap positions to maintain balance but the new foils have worked fine with the straps in the same positions I used for the earlier AFS foils.
