Hi
Check out my latest creation with all it's cutting edge features, including:
- No rocker
- No Fins
- No concave
- [Almost] no curve in outline (approx 20mm each side in the last 200mm of the board).
The "black strips" are carbon fibre 
Rode it yesterday and it goes great.
Nice. Whats your dimensions?
PS adding small heel side fins helps the top end of a light wind tt without removing much bottom end.

It's 1440 X 460 made of 2 X 4mm marine ply layers.
Yes, on the next one I will add inserts so it can be ridden with fins. Just wanted to get this one done to see how the general design will ride before I invest more time and effort in it.
Its super easy to add fin drillings at any stage on a ply core board. Simply drill them oversize by a few mm fill em back up with resin then re-drill to the correct size.
Here's my light wind TT 145x45. I've tried it with and without fins in various configurations. I've settled on 2 small fins on the heel side edge.

What material is your core?
What is the glass layup?
What is the depth of the sidecut on that?
What is the radius of the cuts on the corners?
I found that a good way to do the curved parts at the end was to graph a parabola in excel with the required amount of curve that meets an arc of a circle (15mm radius for me), then print screen and print it 1:1 in word, making sure that the picture has the right dimensions. Print the picture, trace onto template and cut using a router. See below

What material is your core? 5mm vertically laminated bamboo
What is the glass layup? 600grm triaxle with an additional piece of 600grm triaxle in between the footstraps. (to be fair I used too much glass on this board...)
What is the depth of the sidecut on that? Parrallel rails until the corners
What is the radius of the cuts on the corners? Can't remember sorry. I'll have to measure them.
Also I have 50mm of rocker. Thats a bit unusual on a light wind TT. But I live in a big wave location. So I still need to be able negotiate up to and bigger than double head surf conditions on this board....

Yeah nice one. I have seen this and another video probably from you aswell. Convinced me that the flat/no fins/straight outline works pretty well.
I keep coming back to my boards with "square" outline. Why do they need to be curved?
The Bunnings board is excellent for light winds and dead flat water
Science says a square flat tail is the most efficient for speed and light winds.
For chop, add some foot straps and fins and you will have a very good light wind board, the flex of the PLANK auto adjusts as you ride.
For me it was a great experiment on how little you need, to get a good performance light wind flat water board.
I would add some fins and straps and front curve for choppy conditions...
Add some carbon fiber, graphics and a logo and make up some marketing words and sell roughly the same shape for $1200 ;)
A mate makes twin tips, after many prototypes, he found a rectangle no rocker is the best light wind shape...

If you backed yourself you would fund it yourself...... Seriously though. super el nino predicted for spring this year. That means a spring/summer of cranken westerlies and swell in the naki.

Seriously though, the amount of times I have talked to people at the beach and mentioned that I was making a board or interested in making one and immediately told not to try or the idea was laughed off because it is too complex.
I would find it pretty hard to justify the decision to fork out major cash for a light wind board having ridden the one that I built that only cost a fraction. The exception of course is people who are time poor and or don't have the resources to make one.
I went to Bunnings and purchased www.bunnings.com.au/selex-600-x-18-x-1800mm-clear-laminated-pine-sheet_p8490006 ...
I cut it down to 500mm wide into an Alaia shape (roughly like the Naish beast without the waist), added a point, a fish tail, some glass on the bottom and resin on the top to seal it (bunning glue is does not like water!!!).
Works a treat in light wind and is super skatey (new word).
$100 board.
I just grabbed the cheapest piece of wood I could find near six foot for 100kg of fatness. It weighs a bit but I am was never planning to launch myself into the air with it and do grabs. I just wanted to know if I could do it.
1500mm should fine provided you keep enough width. You could try a North Skim Fish shape..... that would be a lot of fun to try.
I will take a pic and post it. It is definitely not sophisticated.
Plummet
Any chance you could post some detail about how you attached the foot straps?
Did you embed nuts or use some type of flat headed bolt?
Pix please?
Is the bamboo core you used that much stronger than ply? I was thinking of using 6mm ply and extra glass.
Not wanting to hijack the thread - I got the chance to play recently on a Naish Alaia that Ant has at the QLD kitesurfari - kind of fun but then Im not really familiar with riding finless boards - and I was having a go in the dead shallows and out in the deeper water and chop - to be honest it seemed to be more comfortable riding it backwards!!
CJ2478 you have inspired me to have a crack a sensible home build - I really don't think I could be bothered with the Alaia shape - but that's a typical Naish thing!! (bat wing kites - what were they thinking!!)
I was lucky enough to score a 3m x 500mm x 50mm piece of paulownia.
I can feel a few big skim boards coming on!!!
Got some stainless inserts laser cut then threaded them.
Cost me bout $120 for 6 boards worth.

Yeah good stuff. I recommend keeping it as simple as possible. I actually had 2 failed prototypes before this one because I was trying to add too many complex features and just general over designing. Tried to do resin edges which was a failure and also had a router failure cutting it out. Another board I just put too much glass on it and it was too heavy.
Hi all,
I was reluctant to reply but unfortunately, I decided to close my DIY kite board building shop in Perth.
In about a few days time, shop.shinai.co will stop working.
Still have a few SS inserts for sale, and a few beautiful hand made boards. Topsheets are gone, carbon, fins and rails too.
Hopefully helped some of you guys on the way and thanks for your support.
Bye for now.
PS
CJ2478 Thanks mate for your order and posting, appreciated. Congrats for your build as well.
JHS, bamboo is strong as, but heavy. 10mm bamboo in 150x50cm size would be 10kg if not more, comparing to Paulownia same size of 2.6kg:http://shop.shinai.co/?product=paulownia-wood-core
I can't believe it's taken like over 10 years for kite surfers (Seabreezers actually. I see more intelligent responses and respect on other forums) to realise you can make just about everthing yourself, especially boards!

doesn't everyone have a 10-ton board press in their shed, just waiting to be used?
