I like the dims (way to small for me but super cool). 5/16" concave at center on 5'6" x 18.5" with a 2.25" center thickness? Lots of curves going on. The rocker profile looks great. I have never worked with the large radius (20ft) concept that you used for the rail rocker. Excited to learn more about that. So no overall concave or Vee out the tail just channels? Nice. It looks like your concave fades in to the front of the board well after the 12" mark to kinda mellow out the center line rocker? I really like how you faded the double inside concaves a third of the way down. I have used the same technique on previous build and had good results. Frothing to see this fin setup from Huie!
The double stringer EPS I got is from Bennet, didnt glue this one myself. Yup, might try a build thread. Keep the pics coming!
No vee out the tail, although it does look like it from the pic, I reckon the tail shape has a lot to do with that (the outside curve of the double bat tail). Also there is a very slight concave added on the outside of to channels toward the rail.
If you run a straight edge across the apex of all the channels in the tail block, its flat.
sorry a bit late
this board would be a record for you still in progress (-:
so to day i foiled up some early trial fins
the fronts are wot we talked a bit of k21-- a bit of are' er' woteva
they are laid up with amazin light weight cloth which is so fine it melts into the resin which is epoxy
the rears are laid up with g 10 and wood which is where i lean these days and have another set of mains underway to match
they are as we wanted abit less total area than the mains-- there a new templte and for yorky so i thought we might call them new yorkers (-:
Can you give more info on your carbon stripes? How did you get such a nice curve, and keep it when glassing? Also, what did you do to even it out, so you don't get a ridge at each line?
Nice glassing around the wings, the last time I glassed around wings it didn't come out anywhere near as smooth as that, just wondering how you did your relief cuts on the wings to get it so perfect?
the carbon used is very thin and quite easy to handle (running out of this stuff in the pic, I got it from the states when the aussie dollar was good, I Forget where) solar composites have some good stuff.
This glue is great to use with epoxy it doesn't cause seperation between layers when hit, like most other glues (and it has awesome holding strength if both serfaces are misted)
I use a lot of pencil lines and have a lot of clean templates to follow.
Im not much of a production glasser (don't ever want to be either), the relief cuts never go over onto the rail (so the glass stays together, on the rail) and the split in on the deck.
The boys at work don't do relief cuts on these type of wings, They'd roast me for it haha.
There are a lot of different way to do the same job. I did my first one of these carbon things about 8 years ago, and have done it a million different ways. Its not hard if you have the time. ha
It’s common knolowedge that the rail shape forms a ‘C’ shape, and also common knowledge that a ‘C’ shape is strong.
It’s also my understanding that if 1 metre (yard) of carbon is stretched 1mm (1/32”) it will break.
Fiberglass has flex.
When a surfboard flexes, the fibres running lengthwise up the board that wrap the rail. They are subject to different stretch pattern, the ones closer to the deck and bottom will stretch more then the one (ones) in the middle of the rail.
Therefor, More stress on the fibres on the top and the bottom of the rails.
Fibreglass stretches and can handle this un-even stretch, even utilise the ‘C’ shaped rail as they work together (before failing) usually wood stringer in a traditional board balances things nicely.
But, A rail wrapped in carbon hates it, the top and bottom of the ‘C’ shape rail will stretch and fail first, making the middle part of the rail strength close to void against snapping. Great memory, but to a point.
As a side line point, I like the idea (if just wrapping the rails with carbon on a stringers board) use 45 degree angle carbon cloth. even the load….
I have seen a shit load of boards snap with carbon rails alone Heaps! No stringer (as pictured). And the all snap in the same spot, under the front foot.
(HS surfboards are the best, they combat this beautifully-much respect to them)
Carbon rail boards reel very springy/alive.
I love the memory of carbon, I believe it has a place in surfboards.
In this build, what Huie and I are doing, we are utilised the carbon so it compounds the strength/flex patterns where we want it (on a level/even area), One thats not prone to fail by wrapping it around the rail. This also gives the board a more ‘traditional’ feel with performance where we need it (IMHO, and from tests) Light/strong/flexy.
Yes I heard years ago that the proper place for carbon was the bottom. But "looks" win out. So on the deck it goes. I don't care about "flex patterns" though and use it only in the tail area to prevent "rot". A net tail patch or Carbon tape. Damage to the tail is the only reason I use it.

hey''
fark the carbon just put some paint on there that looks like carbon and get that thing in the water
i require the rear future box? msmnt/---- is it small or have you just stuck a front in?
I tried to keep the the flex pattern the same for both, so carbon follows the same lines top and bottom.
But, I continued 3 carbon strips out off the tail on the deck for a bit of extra heal toe strength. (Also because, if you saw my last build the deck looked a bit 'naked' where the carbon stopped on the deck just before the front fins). pic included also.
The top and bottom are glassed equally.
You can see a pencil line where I was going to run the carbon on the deck to the wing, but changed my mind and ran it out off the tail.
It's also got an extra back foot toe/heal/and tail block 4oz patch ( a 'U' shaped patch).
No gimmicks or trends here.....a combination of design , function and durability......with some colours to give the board a nice asthetic appeal........a cluster of "New Yorker " fins will be the icing on the cake.
exterimented from the start with this build, so why stop....
I sanded it 120 - 150 - 240. kinda standard here. only weave where it is to be expected with all the stuff going on (passable amount, not much al all)
I cleaned my spray gun and pulled out an old tin of clear 'auto' paint with extra flattening base added. I usually sand my boards at the factory where I work, but this one is a bit different...
It's pissing rain ouyside, so spraying clear+flattener= haze/milky (toughen up cup cake). So I did a double coat with talcum dry rub in between.
All Ok. It's not show room floorstandard, it's light weight performance based. And It's mine so why not play.
NO fins have arrived from Huie, They were sent to my parents, They checked with the neighbors, nothing (one, next door neighbor wasn't home, Hoping they have something).
PIC'S are in the Milky stage haha :/ oh well, next.........
Follow up on this design is where the fun begins :/
One of my favourite things to do is zone out with a few cold ones and make surfboards for fun, not knowing extactlly where I'm going or what the end product will be. (To be honest I was confident but the adrenalin of the build online was exciting, with all the last minute changes)
Right up to the very last hour this build I was semi-winging it.
I did some things that made me cringe and learnt a bit.
But, a cool thing, That I really have no solid idea yet is how far up we are going to put these quad mini (split back) fins, We have a few ideas... They will go 3" appart (and around where the back fin is)..............
See how it rides first then.......................?
:) Damn right, I lost sleep over that problem.
Wow,

I took my girl and 7 month old son over to your island today Huie.
Where were you?
Jet skied around it looking for a place to live hehehe
Huie, You live in an amazing part of the world.

Are you kidding me.
I'm jumping up and down right now, super supa excited...
They, Look Great.
:)
How about I ride my ski over and pick them up, and bring the board over with me? (Board is still at the same stage)
nah wont be there i sent you an e mail will post the fins as soon as i get to mainland
get the bloody board finished i got lots more to try

Huie,
Do you have the same e-mail address?

I see a gap, this arvo. Hope to do some 'home work' away from the factory.
Home is where the heart is (and I can have a beer too) :)
Family + work + surfing = not much time to play with builds at home these days, things will lighten up soon I hope.
Maybe, lay down some carbon and put some futures plugs in... then ?
Glassing? don't honestly know yet.
you get those fins ?
cheers huie
now retired
one month later.
Attacked this thing like crazy today.
I even ripped out the 5min Epoxy (sweating bullets).
Carbon is straight and tight wrapped in some 4oz (lightish).
Not much haze in the epoxy around the Futures plugs, and no real bummbles.
On Track............ Huie, Fins mate?
your holding the show up Buddy !

uh'' wots with the rear finbox? i sent the fins monday '' its now friday? aust post run by a camel jocky
cheers huie

The fcs1 (dual) tabs will fit very nice, on the apex of the centre concave that is 3" wide :)
all good.
But,
I will need that back thructer fin hehe pls.
....................No fins yet at my parents home. They will be there in time.
IMG_4477.jpg
IMG_4483.jpg
pencil lines suck.
I'll have to work on that mmmmmm
/and yes, there is an extra wide fin patch for the fcs plugs.
futures nice and deep

It's great to see you two having so much fun down there on the other side of the world!

Yorky,
WOW... Looks super good man. I gotta get glassing on mine (they will look nothing like yours). Well done!

Remember, I’m a student just like you.

Fibers that take compression load buckle far before fibers that take tensil have a problem.
so basically to utilise carbon efficiently, we need it to stretch and rebound.
... Just carbon on the bottom would make better sence and have the deck real flexable then.
Thoughts?
Just wanted to say thanks. This thread is bitchin'.
Made me want to go out and build a set of fins, among other things!

looks is the only reason these sheep use the carbon/net arount the tail. It does nothing that a nice piece of 6oz or 4oz won't do...
It's a trend, But it Looks cool.

It's a small/shallow.
I reckon i'll have to get your fins tuesday, lets try them with back fins i have then we'll have a better idea.
But, my initial thought is same size as the side, the fin clusted is tighter anyway.
Carbon is already on the top. (no black paint this time around haha) :)
top.

Here is pics of the top and bottom together.

filler

I tack in the legie plug after lam stage with 5min epoxy (just a drop), Then fill it in with the filler.
It gives a nice clear finish, (and if you rub around the leggie plug hole with a paint it gives off a nice effect.
And saves time ha
Gotta say York that is some nice work. Lowel

Thanks DingyMcDingFace. Right back at you, Ya solid.
Here is a few boring pics, In the hot box.
Cooked for 8 hours at between 60 and 70 C (140-158 F).
I put a pu blank in there (single concave) it was glassed in epoxy, It came out as a double concave... Top and Bottom
