A little bit wider at the Pod Kami. About 420 now?.
Is that the new 3d lite your using?
I still like the old one with the wire frame adjustments.
BC is really nice too, it is the best free program out there.
But you have to use cryptonight if you want to look at an AKU file now with BC.
BC wont read AKU properly, or should I say AKU is tightly encrypted.

Exact 420mm, but i push this board into an stinger design to have a longer pod with more flex. my purpose is to get front fins smaller than the rear one to bury the tail . So i want it as much flexible as sponger got it and step my back foot on that bluddy thing to carve the whole board with the help of my paddle
I like surfing backhand, i'm thinking like a backsider, front foot in the wall

I'm using a full design version of www.shape3d.com/Support/VideoTutorials.aspx i'm learning to use this CAD shaping to project all the board would like to do, like you we get lot of, that kind of software allow to make our knowledge and dreams come true... at least on a PC screen

Wow, that is looking good. I love this flextail concept you are using... wonder how much my kids want to use their body boards this summer?

Cheers Chris

I went for a paddle at lunch time today Kami, if you haven't started shaping, I'd leave the tail the same width as the old one, you really can go narrower / have less surface area than experience tells you. I think I can go down to 28.5".

The thinner rolled nose tips look good too. I kept paddle bashing the front corners, have to relearn how to paddle.

You get the right eye...this is a hard decision....but i might leave like that because can be Ok for rail to rail transition ( we got a paddle to make this beast turns rail to rail ) and for the most important effect : i believe in the flex tail to bend while pushing forcefully in bottom turns.
Last point this enlarged area involve stability...like you want to do narrow width on your next board, mind that this tail width is giving stability as much as the widest point of the whole board .

I'm going to enlarge the flexible area by increasing the distance of the flexing part. to do it i will remove the EPS of the shaped blank under the grip position by XPE 45kg/m3 .I will have a soft deck that way with the bodyboard and some XPE like a thick tail pad
The bottom glassing will be in one cloth 200gr carbon fiber as a sponger's carbon stringer .

I expect to do some cutback with this Flex tail and dig this wing in the face with my front foot and lay back some backside curl .

Thank you to make think about reinforcing the front side of my board, even the deck got dings from paddle beatiing.

I think being a bit conservative and on the wider side is the right thing to do..
Paddled the Mutant in some light onshore bumpy beach breaks this arvo, glad I made it 29.5 wide now.

Looks awsome wish i had the skills you have, Love the vangaurd shape.

Is there really that much difference with the flex tail?

Im getting a custom board made at the moment and have the option of a flex tail would you recommend it? My main concern is the durability of it ect.

Casso, Piros :I feel so good to hear your greetings..
I start making my own board in 69 when i was 15 because there was no board in France to buy or so expensive. But i like shaping creativity too. SUP board give me a second chance to have the enjoyment to create what i expect to own , again.
I will be retired in a year and a half, sure i would like to see the people who shape and carry forward the shaping knowledge of our elders.
Honestly i better like the natural rocker and low railer's surfboard from Australia rather than the Brewer's Hawaian/Californian influence as we still can see in Naish 's board for example.
Aussies will show the hot stuff again

To makntracks: Flextail work for sure, It seem to me that it has more purpoise to be with SUP because flex tail is '" like a shocker" to the extra width of the SUP tail.
Flexibility can be a technical response to large plan shape hard to sink while going through water.
Yes, Flextail can be fragile and need care while loosing the board getting stamp by wave because the leash bite the soft foam.
But Boarbumps solution look way stronger than mineCheers

After glossing last night ,this morning i see how is it looking .
Can be too much lift tail but it's a wide tail, i expect as a loose and reliable carving shortboard SUP
Sure i will need to do more stretching to master her

I have to stick the tail block, deck grip and GO

4630 grams without grip and block

and thx to king of the point and colas...




Fixing the tail pad is a grave concern, i think a bit too much forward but i get my back foot on the sweep spot and my front one on the entry rocker
Anyway i fix the grip like this and will see this week end how it will going

It's so exiting to expect the result of what did i do

Back from the first session with this board:
Glassy to offshore slight choppy, 1 or 2 foot very nice wave, peaking rolling and getting faster in the inside onto more than 50 meters. Crowdy but don' care because i quickly understood i got the right tool to catch waves through it.
Paddling prone feels imediatly fast and easy , standing up...i find the right spot naturally and balance as well, no matter its width front and side balance this is easy and far out more confortable than her pointed sister of same volume with larger width.

Taking off is just ...EASY as Colas did watch the low entry rocker, then just flying off bottom turn and well...it's like shortboarding on a board of same length with width boosted glide and as wicked as possible like King of the Point said.

She is able to allow all the surfing maneuvers repertoire.


IN 3 WORDS: FAST, EASY ANF FUN

6'5" 27.75" 85 liters and i weight 77kg, I thought first was too short, now i do think NO, this is fine .


Let's go on Vangard style this is the key of surfing's pleasure.

Merci, she has been tried by a talented surfer of same weight as me but just a forceful 40 years old usually surfing on Réunion Island. He is stocked of it and all the surfers who watch him are stocked as well of what did he do with this board.
More glad of the board than the freedom to get some waves out of reach of bull shark's teeth for sure
Her want already a 6'8" under 28" no more 90 liters version.

Anything new with your flex tail board? Do you still like it or have you moved on to another board? How do you keep the EVA foam from getting torn up from your leash?

A lot of fun surfing those flex tail specially the last session in a 6' 12second perfect conditions on the green one 6'9"28", i really feel the tail torquing me out of carving move
Some time i think to flattened the tail to prebend its stiffness, sometime i don't, like during this session where i really match myself in a mad bottom turn or arching the face on that board because of its bonus rocker...At least humble saying; i really love its feeling .

About torn up the tail, i will simply laminate more carbon fiber across the rail and up to the front fin. This adjustment is enough to avoid towing leash effect to torn up the edge of the bodyboard material.

Next project will be a 6 channels board with a flex tail, with a stringer IN the tail laminated like a ham in sandwich of polyethylene foam. fins plugs will be attached to the stringer with extensions sticked to the carbon layers. Want to be closest mechanic as the fishes tai
On this picture, note the extensions plug fins
