Ive got a previous model F4 with a 120 fuse. Just looking at yours looks like they've added some front end poke to the new one. Whats the distance front of mast to front edge of the wing on the two fuselages?

looks like theyve changed all the joints too, added a few bolts too.

Here is a (French) review of the new F4:

how many much in oz ???

Mmmm foil porn. Will there be tears the first time it touches a sandbar?

I think maybe a smaller front wing would be good to try as well especially if you aren't focused on course racing.

Yes slalom wings may offer a different experience
I don't sail upwind / downwind I just sail any direction
But for their size I find with my limited experience on this kit (4 weeks) the 900 and 1000 go ok
So far I have only used the 115 Plus
-1000 wing 2sec 23.8kts, Duck gybe Alpha 19kts
-900wing 2sec 25kts, alpha std gybe 21
I am just a free rider not a pro, in the right hands there is more to extract,

Details Requested
Front Edge Wing to front of mast 115 plus = 435mm
Front Edge Wing to front of mast 115 Std = 335mm
5 bolts in the front wing, no worries with torsional loads
Cheers
Tony

Cheers for that. Looks like improvements everywhere on what was a well built foil to begin with

if you're ever thinking of selling it (since you just bought it) gimme a call

No worries, I think this one will be with me for many years...
If you want any further info feel free to PM me

Tonyk what differences have you found between the race wings and freeride wings?, like upwind angles versus crosswind, wind min. needed to get up, maneuverability. How much pumping to get up in light versus stronger wind. The NP glide probably did not require any pumping. I have thought about getting a race wing for my AFS foil, but very happy with the AFS freeride wings so not sure it would be worth the expense since I would also need a different stab. for the race wing.

I don't like to pump, the 1000 wing goes early enough,
F4 is designed to go to wind so it does it much better,
I sail flat water and don't find the F4 too limiting in maneuverability for the type of sailing I do

Okay, thanks tonyk

I just had to use your tracks as an example of what can be done on a race foil for a blog post at boardsurfr.blogspot.com/2021/02/fun-with-polar-plots-fin-freeride-foil.html . The angles you're getting are pretty amazing!

Wow Thanks, I have not been trying to point so far,
so this is a good sign that F4 has got some racing legs in the right hands

I can get close to the same angles with my AFS F770 wing, little less with the F1080, was using homes on the waters edge as a reference point for upwind angles.

Unless you use a GPS it's impossible to accurately measure VMG based on angle.

Tell that to Magellan!

Sure, whatever, your narrow board and freeride foil is producing just as much VMG as a race set-up. Starting to wonder if you realize how foolish your posts sound.

But Sandman made no claims that I can see about his VMG.


And you get green thumbs?

Actually this is a very interesting discussion. Guys in Seattle discuss, too. Angles. The only good way I can really see my angles is to look at the gps track once back off the water, and I have uploaded the track to some app that displays it (like strava). At my foiling sites, I can see from shoreline how high I have gone, but I also can see how slowly I got there.

Hey Sand, if you add a race wing without changing anything else on your AFS setup, you might not notice what it can really do. You might need to get a longer fuselage and smaller stab, too.

One thing about F4. They make really really good stuff. They have a pretty good fleet of San Francisco foil racers as their de facto team riders.
