Hi Rob, as you ask me in a message there is some more pictures of this board, this board works very good .
one of my first waves with this 6'9"
before moving the fin


I added one plugs FCS to move back the fin but I made a bad mix of epoxy, was melting and finally pop out

the board in Guadeloupe (french Carribean islands) where I surfed it in perfect reef waves , note the FCS plug torn off .
So I gave the board to a young Super, his father will take away the flex tail to find a SUP 6'4" swalow tail .

By now I'm doing one new sample FLEXTAIL SUP 6'9"/28",03 and a FLEXTAILsurfboard 5'2"/21"0.66 for my son.
Anybody did try something similar or any infos to make me think about?

No vid, sorry I spent some much time to succed standing on this that I bored my wife holding the camera but I swear I had ones best ride of my life on this board. The Flextail hollows carving turn amazing for its dimensions and a very soft feeling in the offshore chops, something like snowboard in the powder

I was there for holidays in end of january to begining of feb, I stand on the offshore side wich is looking the West and sometimes 3months of the year mostly some ground swells comes down the North of Atlantic. It happens when NY gets very frozen so it's depressing throught the Gulf Stream. Rest of the year it's trade coming East from Africa, oneshore and winswell on the East side. Remy go to Pacific side of central America , much reliable for surfing

TX Deano, this FLEXTAIL sample on a pintail surfboard is a lot inspiration to me.
I wonder the foam's flextail is made of polyéthylène like the one used in bodyboard? Do you know anymore?

My reason to set a flextail on a SHORTSUP ( can be done too on a 8' SUP fish tail as well), this reason was to avoid cavitation providing from the wide tail of these SUP, to sink easily fins and rail => more drive with smaller fins easier to dig tail to crank bottom turn...so this is the way a flextail SUP is going !

TX again Deano

Bit of info on the Outer Island website.
http://www.outerislandsurfboards.com/boards/flextails.html
Mitchell Rae is an absolute master shaper.
They are amazing things to surf in powerful waves.....the tail loads up in a turn then slingshots you out of it with crazy speed!!

The last 1' or so of the tail is uni directional carbon around 2mm thick with EVA foam over to maintain rail shape & volume.
If you grab the tail in your hands you can flex it....so it's not super stiff.
Good luck with your next one!!

hi, Deano : this is my next one, made with a bodyboard PE, I like to torn off bodyboard.
I stuck together EPS's board and the PE parts's bodyboard with a chewy epoxy resin and laminate one 4 oz glass on bottom, can be a bit too stiff by now , I will sand down a bit to make it more flexible later after trying more waves Next time I will stick a slick material instead of laminate a cloth...
6'9" /28" and thickness 12 cm , boxyrails blended into the 50/50 body bodyboard rails, with an old style rocker and rails from sinle fin board, The whole thing floats my 76kg with 87 liters buyoncy and goes very well on small wawes

She is well balanced a lot more stable than my first one, the white upthere .

I have no guts but just got a sure back Tx Deano for the info about Flex tail









I made a board for my son 5'1"22.5", this system is diferent one , made with bodyboard too but like a hinge along the rail with extension on FCSplugs to let the fin attached to the board and the tail free to bend and release. I will do it on a ShortSUP soon!

Finding the fish tail too loose with some stress onupper body part of the bodyboard as i point below:
So I laminate some carbon fiber to make the tail stiffer and mors snappy like a real fish

Kami,
I second Deano's response. 10/10 for innovation, and backyard skills. You've left me dreaming of getting back on a sub-7ft board!

Yes Tang, let you step on "sub-7ft board" with just a bit more flotation than your weight and a paddle around your nose's height, needs a bit of training... It is really worth it.
The innovation to use the flexibility of bodyboard PE with carbon reinforcement make this wide board really carving and very loose despite of its tail width . She got everything to have fun riding forcefully a wave unless good surfing conditions, glassy or slighty choppy, no onshore, backwash , etc...

I'm allready working on a new Flextail same dimensions but with more looking like a modern shortboard, rocker, outline a bit like the first white one.

Cheers

You,are right, control flexpatern is a goal to this technology. As well as Witchcraft, Mistral made one flextail it too :







While thinking about the Mistral board 's technology , as shown up here I did the board for my son , this 5"1'/22" is made of the two oblic hinges with spring effect sliding along the pipes holding the FCS plugs, the flex of bodyboard wings working as shokers. The complement fact than fins are attached to the board in straight contact below the back foot pressure.







I agree that this system is complex but my son(5'10" 73kg) is happy of the dad's board, the extrawidth make take off easy, loose and the flex allow carving with this very shortboard.

As this tail works so good on 6'9"28.5" 87liters 5 fins , I' m going to build an other one shorter so It will be 6'4"29" 90liters TWINZER . I draw on my computer with SHAPE3D and order the blank to the EPS provider. Now i'm going to shape by hand and adjust parts of creschent tail red bodyboard



Computer views will be very helpfull to shape what did I draw , I call them " BadBoard" because this is a SUP made from sponge

Spring is coming up here, so i follow building my 2014 summer " BadBoard" as shown before shaped by hand following S3D file.

I cut out the both tails of body board and EPS blanck to stick later the bodyboard parts on EPS laminated blanck.


This is what do i like more, sawing bodyboard



I 'm glad to connect properly bevels od both EPS shape and Bodyboard one.


Next step now is to laminate EPS.

Looks great but not sure about the H2's they have alot of built in cant and narrow base , plus they are a weak fin and probably crack at the base. Let me know how it went.

About H2 cant, i love it because this fin keep the board holding while getting on the rail or holding high line in steep face.
About toe in, i went parallel to stringer to make up for H2 toe built in .
I agree this fins set up can be too loose, i expect getting this fins set up stiffer as i fit fins a bit more back ward as usual and there is no tail lift.

Controller from Futuresfins might be better for my fish kind of board but i have a bunch of FCS fins and H2 one was my favorite fins while surfing in Bali with Weber's board (Spoon and Fatburner)
I never have trouble cracking the base of the fin even pushing on them under some section...
Designing this BADBOARD 6'4" shortSUP with flatter rocker as i can , I got inspiration from the SPOON of WEBER, those H2 fins worked unreal on the flat tail with no tail lift. I like the way the H2 fins lift up the nose of board,
Here in small Ulu's inside wave few years ago, watch the hold of these H2 imagine with paddle in hand







(i better like Impossible's waves)

My Badboard 6'4" 29,25" 82 liters for my 75 kg old meat. What did happens at the end of this wave? can be a back wash effect and the chunky nose of this board doing a sudden slow down
