I’m 67 KGs with the 685 and just had a parawing session in my local river with 7 miles of fetch and gale conditions. Swell was thigh high and tightly packed. The 685 was plenty, but the 800 would have likely been more user friendly.

Are there any plans for a universal tail fuselage with 2x6mm screws @30mm bottom mount?

Hi, we’ve thought about it for testing purposes and have used similar connections in the past. Would require us to make the fuselages and bolt on wings/ shims which makes the system more complex.

I believe a universal fuselage with 2 screws for the tail, will make more drag. All the little things add up to a lot. Let’s keep the drag low, low, low.
I was going to ask the same thing. F4 wouldn’t even need to make a tail necessarily, just the fuse with tail open for experimentation for the tweakers. Plenty of 3rd party options to explore.
this is the best bloody (not) review on this website 
thank you
how did you do the text overlay? is that an ipad app?

Thanks Matt. I believe it’s the only “not a review” too. 
I just scribble that onto notes in my iPad. Screen recorded it, speed it up and luma key’d the BG.
My handwriting is shit, so it took me a few goes.

That’s among the best surf videos I’ve seen!!
here is an overview from Dylan, not a review!
Thanks for putting this together - I was wondering about sizing/range. Very convincing!
Have you been able to pair it with any more surf-oriented tails? Seems like everyone is using the same downwind-oriented tails (e.g. xs135, etc) in all the footage I’ve seen, and just seems a bit nose-down for the surf zone. Wondering if something tuned a bit more like an f-one 160c would put more front foot feel into it?
Their website just got an update in the last few days. Different stabs on different parts of the website now. Looks like new surf stabs and super high aspect dw stabs incoming.
If anyone has thoughts and experience to share on stab selection, I’m all ears. I was struggling to choose a couple of stabs appropriate for my level when the choice was just fuse length and area.

I’ve only used the 135 XS with it. I know what you mean about more front foot pressure, I’ve liked that in other setup’s and would be interested to try something, but I’m not certain that the manta needs it. There are some positives that may be lost.
I’ve heard rumours of a 135ish surf stab too. 
for @Chrisrad99 to weigh in here. 
Curious about a few things. I see stab shims on the web site. I’m assuming F4 windsurfers are using them. Do they also fit the winging stabs. Has anyone experiment with them.
The nose down look on that wave might be a mast rake issue. Lack of enough rake for the speedy F4s. I believe windsurf racers run between 3-3.5 degrees mast rake. Mike’s Lab wingers run about 2.5 degrees rake. I run 2 degrees rake winging Code. 1 degree foildriving Code. Rake measured deck to mast fuse saddle angle difference.
We know Armstrong builds 1 degree rake into their mast. Is any rake built into the F4 winging mast?
FYI, waiting on my order

Hi,
Thanks for the questions and interest…… we’ve been trying to catch up on both the website and getting gear out the door… apologies for the list. Both the 135 standard and new 137 surf stabs are amazing, the 135 is maybe more slippery, and the 137 is more for turning. We been expanding on these two with different sizes. The 137 really is for more consistent pitch control and better role response, the standard series is for speed and efficiency if that help. Both pump well and great at digging out of slow situation…
- we had developed shims for our old windsurf foils these are no longer applicable for the GP series foils. The rear stab can be shimmed at the connection a limited about - ±1.0 maybe
- there are new surf stabs that are lower aspect ratio based on a elliptical design - 137 sqcm. These are a bit more grippy, make the foil looser in roll, more predicable in pitch. More resistant to the tail sliding on hard turns. More powerful sections, so we are all adjusting to smaller area numbers (more sizes in the pipeline)
- The 135 stabilizer is flat, so more efficient for DW and racing
- Most of the new boards have rocker, so we’ve not put any angle between the mast and fuselage. The windsurf foils have rake to accommodate for the board design mostly. We design our boards to get the right touch down response
Thanks for bearing with us as we sort out the website and products categories…
Br,
Chris

I’d love to know if the tapped inserts inside the mast and fuse are stainless steel, titanium, or brass.
If stainless steel, then I’ll add Tef-Gel. If brass or titanium, no tef-gel.
The inserts are stainless steel.
Thx,
Chris

you guys need to get the Manta and the AFS silk together the feel sounds very similar but it’s way older
also i was listening thinking the tails are maybe going the wrong way, it sounds like you guys had the wrong tails or whatever but then Chris calling in I wanted to say it sounds kinda too grippy? the reason i say this is that the Silk I’ve found that a super chopped stubby small tail with no turn up and just very basic is really fun for surf, just lights the foil up.
My guess is that you don’t want or need that grippy feeling that Chris described, unless that means the foil section is grippy?
Also do a back to back of Silk and Flux with this foil, it sounds amazing 
Here’s a look at the planform:
I’ve experienced the 135 XS (DW tail) ‘slip out’ before in steep DW conditions. I cranked a really hard top turn at a bit slower speed and the tail slid out like a tail blow on a surfboard - but heres the thing, the foil gripped right back into control and I rode out without touching down feeling like some sort of pro, but i’m just a 41 year old punter. This was with the Orca 685. I will probably add a 120 surf tail if the reports are positive, although that looseness of the 135 is not necessarily a bad thing.
