Has anyone tried the new tectonics FURY.fins looked on there wedsite not much info as usual. All it said was it leaves all there fin range behind must be a powerful foil ????

It clearly does leave every other tectonics fin in the dust...can't seem to get any info on their other fins now lol

From the info I obtained, it's machined out of a new type of G-10 that is supposed to solve both two major issues with machined fins: 1) twist control and 2) durability.

In my view it's extremely interesting. After all there's no need for carbon in order to control twist and make foiling fins: one just needs proper fibers orientation and there's no limit to do that using "custom made G-10".

After all, not much time ago almost all of the "good" fins were in machined G-10; only very few moulded ones were considered as competitive or leading; and most moulded fins were considered as a second best option when precision CNC was not available. Now, if one can make a machined fin that foils as a carbon one, maybe such times will be back again. And, the Fury brings Dennis Parton's signature.

I am ordering a few ones.

how do you make custom G10

Meanline fins are generally all full custom G10 fins also which are made according to your weight, board type and what you are wanting it for. The difference between a good fin and an average fin comes down to the preperation and the finsh of the fin. Obviously foil shape is important also, however you find that fins which are generic and not custom they suite a specific body weight (usually PWA sailors, 90-100kg). The majority of G10 fins today are mass produced which explains why a lot snap and have huge stress fractures after not much use.

In Maui this year I know a few people who tried the Fury against the Meanline SX Phantom. Generally the guys who were bigger liked the fury (100kg) wheras people between 70-90kg prefered the SX Phantom.

how do you make custom G10

As I said mine is only guesswork based on few info available. If I was to make fins, I would like to have G-10 made to my requirements; and that would have both 0°/90° and 45°/135° layers; who knows what exactly works best, probably it would take some trials and tests, probably having the 45°/135° layers (mostly) in the middle and 0°/90° (mostly) in the outside would work nicely, so to have a progressively flexing tip and maintaining proper torsion control instead all the way to the tip (as the fin is tapered, so outer layers mostly flex resistant would be machined out towards the tip).
But I understand what you say, if it's "custom" then it's not "G-10".

I don't know anything about Meanline fins, is there any info available?

Phil McGain seems to be enthusiastic about the Fury, and I don't think he is any close to 100 kg right now (as he likes to compete in Triathlon). Micah Buzianis also spent nice words about the Fury and he is closer to 90 kg than to 100 kg now I think. Hopefully me and some friends of mine will be able to tell in about 2 weeks time or so.

Yea Meanline fins new website is being built as we speak. However, if you want info contact Kai Hopf (info@meanlinefins.com) while you are in Maui and he will have some fins you can try for sure also. I would be interested to hear your opinion the fury vs SX Phantom. For updates you can always look here also www.facebook.com/meanlinefins

Yea not sure exactly how much they weigh but before I left I went for a bike with Phil and he said he was 88kg I think. So im sure Micah is in the 90-100kg bracket for sure.

thanks for updateing geoITA I have always thought g10 was fiberglass soaked in epoxy resin and the compressed on a slab and baked , I would imagine meanline would have to be laying those layers the same length of the fin and then machining so they can get the layers at the exact angle and % to control twist and control

I think usually many fins are cut from one large piece of G-10. I also think that twist control on G-10 fins was usually obtained via specific outline and rake angle, until now. From what I can understand, in the new Fury it's the material taking care of twist control, this is why I suspect there must be "angled" fibers in their "new" G-10.
The Meanline website is under construction since always ...

Where can I find this info? I'm contemplating getting a 37 Fury.

the main reason most companies prefer cnc is they can be mass-produced with less labor, with molded fins the mold has to be prepared before each layup, after loading the mold it is out of action until after the cure and then the fin has to be finished
after saying that the molded fin has to be far superior to a cnc , with a molded fin you can choose what fibers and where you want them , I have found the ideal layup for a 47deg fin is 70 percent unidirectional carbon laid at different angles with 30 percent glass woven roving's and glass satin weave , I dought you can get a layup similar to that from a cnc made fin
it will be interesting to see the layup of these fury fins

I've been very pleased with the moulded fins I have (select Vmax 1.0/2.0s) and some Vectors but curious to see how this "new"G-10 performs. About to place an order for a 35/37 fury and hope I like it. Being one of the lightest sailors in my area, it's hard to sell used fins under 40cm lol

Can't tell for sure, but I have a few impressions and thoughts.

First of all, the response of G-10: I like it much better than carbon fins', it's "quick", springy but damped at the same time; but this may be personal of course.

Second, as Keef points out well, making carbon fins requires lots of tests in order to find the "right" layup. But then, it will be "ideal" for that ONE fin size, ONE sailor, ONE sail and board and conditions. So in the end I am totally sure you can get a super fin by moulding it, but usually you have to be a really serious competent PWA sailor in order to have a choosen quiver of moulded fins with "ideal" characteristics. Most people use to have very good carbon moulded fins, but each "should be a little more this and a little less that".

Third, years ago, before someone understood it was possible to make fins that are both very flexy and with totally locked twist, indeed there were some few extremely good carbon moulded fins available for competition (Deboichet and others); but some G-10 fins were just as much competitive. I have to add that it was not easy to get a "good" Deboichet, as different softness options were available and most sailors weren't even aware of that!

This is to say that in my view the moulding process, despite giving the chance to choose a specific layup, doesn't own a definitive edge against the machining process, apart from the chance to use "angled" fibers in it in order to lock the twist. But if now "angled" fibers may be used in CNC'd fins too ... we will see!

P. s.: right now I have G-10 Talons and carbon moulded Rockits and Sonntag SL-P's.

just purchased a couple of the fury fins 32 & 36 very nice finish the G.10 FR-4 they use to make these fins are fairly stiff aft 20 cm to the base in both fins the tips are really flexy.which probably makes em so fast.they are also lighter in colour than the normal G.10 jade green color.looking forward to strap one of these bad ass fins to my new isonic.

Looking forward to your impressions!

I decided to for it! Went for a 37 and plan to match it to my 2010 iSonic 94 + KA koncept 7.5.

Was either a 37 canefire, clockwood, or Tribal fin. Will probably buy a smaller size clockwood for those really nice days

gavnwend,
no wind yet?

l will give some feedback as soon as the wind gets a bit more consistent. waiting for a wild seebreeze or southely l have been using sting c3.which are good fins.l think the Furys will give me that extra top end.

Mine just came in today. Will upload pictures later tonight. Will be using it this weekend!

Really light! Flexy almost to the mid point of the fin. The new fin cases are really nice too! rubber material. Will get to use on the water this weekend

So?

Still slogging back to the beach?

the wind just switched of had to swim in early season nutter.

Was able to use my fury 37 yesterday in light winds. I weigh 63kg and was using the fury on a 2010 iSonic 94 + KA Koncept 7.5. The wind was around 13-17knots with some gusts up to 19/20ish. Will have to use it a bit more to get a better impression but my initial impressions are that it hauls ass downwind and across. Was comparing it yesterday with my Vmax 2.0 37 and feel that the Fury was a lot easier to control. Speed wise on flat water, it's hard to say which was faster as I didn't have my gps with me. Upwind, the fury was proving to be difficult. I had no issues spinning out with the Vmax but with the fury at the same angles, I kept spinning out in the strong gusts. Kind of felt that the fin was a bit too soft. Could also be a trim issue so I'll try playing with the rig a bit next week (when the wind comes back) and report my findings.

They do let go (spin out) when pushing up wind.l think the profile of the furys are purely for downwind racing .the control across the wind is not so good either.l mainly brought them for speed on a broad reach .maybe go up a size for general blasting.l think the talons or goldwind range are better for slalom in messy water state but the furys are a wild bad ass fin.they truly are dam fast especially on my new isonic.

In my experience it may happen, when the fin doesn't provide enough lift, that the sailor instinctively adapts his stance looking for better lift. This may lead (in my case at least!) to higher back foot pressure thus obtaining a) higher fin AoA, and b) higher board nose. The latter "works" in terms of reducing (or making it negative) the fin rake angle. But reduced rake, along with better lift, also causes poor control.
Solution may be: either keep the sail better sheeted in and nose down, so making for better speed and therefore higher lift (I am not able to do this when I have control problems!), or use a larger fin, or use a different fin (more powerful).
On the Tectonics web site is published a table with the fin (Fury) sizes used by expert or pro sailors. Most are using 37 - 40 with their 7.7 - 7.8 and medium wind boards. But I won't be using my 7.7 in the same much wind they are using theirs, probably. So I guess such sizes will be OK for me with my 7.0, and I guess the 7.7 will take 40 at least. I ordered a 38. We will see.

Have you tried Vectors?
Vector Volt 2 and Vector Volt 2 Carbon... epic fins!!! I use 3 of the carbons at a time and still go pretty well
Heaps of them did really well at last years LOC
The Delta speed fins if you you looking for some serious speed ( Isaac De Vries 42 on his first speed testing last season after injury).
Not enough lift? try their canefires... personally more lift than i can handle but solid fins!

I used the Fury 40 today with my JP Slalom Pro X 66 and North Warp 7.8 in 15 - 18 knots. The fin felt very slippery and fast, more control in the chop allowing me to push for more speed, felt locked in and safe when going deep down wind. The board trim was nice and high with a lot less tail riding.

Mine just delivered, eager to see and to test! I hope 38 won't be too small for m?112 and 7.7.

finally got to try out the new fury x11 on my new isonic 90 . off the wind excellent at times thinking feels smaller than 36cm.pretty controlled going across the wind in chop not so sure about pointing up wind feeling it will let go probably need a bigger fin like 38cm all in all these furys are wicked for control & speed.

I agree, my 37 on my isonic 94 (60x23..something) blasts downwind and across the wind with my Koncept 7.5. In complete control but would probably have to go up one more size for upwind performance.
