After a few days with my new board, i can say, i am happy with it. It works great
Cool! Can you share the design of the board and why you headed into that direction? From what i see: quite low volume, narrow tail, wide nose, what about volume distribution/thickness, What is the board best for, what are the drawbacks? Yust curious to know and compare to follow your route one day.
cheers
Thank you.
I just started building without a plan. I wanted a small board that looks cool and fits well in a car. i think i made it. It is perfect for freeride. Once you've made the start, the board is just a stand anyway. Small Board makes the foil more manoeuvrable.
Don't you feel the lack of width on the back foot for going upwind?
No, it works perfect going upwind.
Oh, I felt was lacking some width on mine and made my new board 65 cm wide on the back, and it works...that is probably related to sail size...and skills, for what I see you have few session on top of mines under your belt :-)
Edoardo,
Congrats on your build! Fantastic work!
Tail width is very much related to sail size. If your biggest sails are in the 5 meter range you really don't need tail width for getting upwind. Tail width is a very good thing for stability though! I ride with big wings and small sails, I'd say about 90% of the time I ride with the toes of my back foot on centerline while going upwind. Only in 10-14 knots of wind on my big sail a 5.2 will I move my back foot out on the rail. When powered up there are times when my back foot is actually slightly downwind of centerline while sailing upwind! I notice that when sailing in the waves, particularly side shore where I am surfing the wave to get upwind. I also take that stance sailing upwind in confused chop or when my front wing is too big but I just keep riding it.
I built a board a handful of years ago that was a shortened version of the race board designs, 83 cm wide at the tail with outboard straps. When I sailed it with my 7.5 it felt perfect in all conditions and I was amazed at how much sail the width allowed me to carry. With the 4.5 I often had too much leverage while sailing off the wind and had to take an uncomfortable stance to balance it. That board and the experience of creating it was so worth it! Even though I ride something completely different now I learned a ton and it helped me decide where I wanted to go with my gear.
I bet you're gonna love your new board! You have designed a board that will give you options to explore different styles. Go ride it like you stole it and then tell us about it!
Thanks for your kind feedback!
By the way I was inspired by your attempt as well.
I so far had only few sessions, one of wich with 6.7 and I was pretty comfy riding the board in the straps. with my 5.7 I felt still comfy but the board got I little sensitive, was moving a bit on the Yaw plane, but the wind was really light for that sail I would have better been on the 6.7 instead. I bet the width should help also in handling the board in overpowered conditions much better, by just leveraging on harness and body weigth, with the old board this was a limit for sure. This board outboard setting should be liking more a powered up situation with a touch more sail than I would use with the more centered stance. I still need to explore the full potential, I also have inboard straps with central back so I can try that configuration with smaller sails as well...will see. So far I am very pleased by the board, much better than I was expecting...after very much design and planning the outcome surpassed my expectations.

Woop Woop! Surpassing expectations!
Completed my second custom board several weeks ago...thanks to the posts here this thread was helpful!
150 litres, 79cm wide, 210cm long. Full PVC core, vacuum bagged.
It's been out a few times in light winds - sails nicely. I managed to get most all of the build on video - see link below, and some footage of it sailing. If anyone wants to know the lamination schedule used or anything else not in the video I will be happy to share here.

That board is a very nice, easy to ride one. We swapped gear when it was setup with the superflyer on a light wind day. Was careful as I didn't want to bang up the great work he did. Tried a few jibes on it without falling in.
It looks great in person, as do his other boards.

What brand is the DT box? Ones we can get here don't have such thick chimneys
The Tuttle box is home made also...you can see how I built it about 30 seconds into this video:
Thanks. Can build my own too but not time efficient for making custom boards.... rather spend the $$ than the time
I am into tracks due to half the price and just as strong ..... just like i used in the board this thread is about 
and was only wondering about a really thick DT as i replace a few on IQ etc. The carbon Chinook one is great and i have used a few but again, if there was one avail that is thicker i would try

Thanks Mark. Your boards look amazing...your original post was one of the things that encouraged me to try building a foil board.
Agreed, I would have preferred tracks and would have gone that direction if I didn't have Tuttle foil gear already. Do the Chinook DT boxes that you have used have enough room to accommodate a flat head e.g. Starboard?
Yes the chinook DT is equal depth front and rear. Its a good product but the Cobra one seems to have a little more material in the chimneys
On the other hand the Cobra one has had front edge fails with some thin material so maybe the QC isnt quite there
GulfWinds, Thanks for the great video of the build! I learned a bunch of great tips! Fantastic work on the board!

Nice board and nice videos. One question if I may ask: I got problems with getting a very consistent flat bottom on the rear bottom of the board, somehow after the vaccum process it came out with areas that where depressed a bit (0,5-1 mm), I had to add another PVC layer to work on to make it flat. Did you had the same? If not how did you avoid it? If yes how did you overcome it? Thank you so much.

I didn't have that problem and don't have much experience so can only guess. Maybe too much vacuum pressure? Did you use a pressure gauge? I kept mine between -0.2 and -0.4 see below for all steps.
Or, could be the density of EPS? I used 1lb/ft3 (16 kg/m3). I would imagine that lighter weight EPS will compress at lower pressure. Or inconsistencies in the EPS you used?
Others may have better answers...

Thank you for your kind answer.
Yes I used a gauge to limit the vacuum level, and I was setting it below 0.4 as you did, the EPS I used was 18 kg/cm, though I was not able to find a block of EPS so I used insulation EPS which was 6 cm thick and glued them together to make the total thickness...probably this led to not consistent behaviour against compression...

?si=x0TjaGTH59c-TR7A
Yes, I couldn't find one to buy either. This is the 3rd one I've built...Used about 20 layers of carbon so its about 5mm thick which seems to work. Also fixed a couple of problems with the first one I built.
Wow. What is happening with the screws at 2'40"

In planning...
I was wondering when you would have a crack. Looks like a good outline. What length, width and volume do you have in mind

The screws at 2'40" of the video are being used to pull the wooden plug out of the mould. It takes a lot of force. It was the third (and final) time I used that plug to build a foil box, so the holes were getting a bit messed up, and took a while to get it loose!
If building a lot of boxes would probably be better to mill a plug from something more durable eg aluminium and tap the screw holes. But for one-offs, wood was easy and worked well.
I finally finished this one and have gotten a ride. This is a recycling of the first board I built. I was curious what the super compact approach would feel like at 140 liters particularly in displacement mode. So I cobbled this together using scraps and recycling tracks. It's cheap, quick,dirty,ugly and heavy but I learned a metric **** ton!
It took a minute to sort but by the end of the 1st session I could uphaul, slog and even low rider freestyle a bit. While it's possible to do this it's WAY harder than I would want for my daily driver. This is what I figured and wanted to find out without spending much money. Now I have a data point including all the hydrostatic and stability info my software (Rhino/Orca) provides.
I love it in the air! I really notice the reduction in swing weight and less catching of the nose when low or carving.
After I ride it a bit more I am going to cut the tail off square just behind the foil and see what happens. I still have interest in this type form for a high wind optimized board, I would not be surprised if I tried to build a new better one or picked up a used Wizard 130 some day.
I the mean time I am starting a new build searching for better light air potential. I am trying the Kalama e3 concept at 145 liters. I will pick up the foam tomorrow! Details to come.
Nice work! That was a good idea to recycle the board.
You've probably considered this already, but a less drastic option before cutting the tail off in the future might be to install tracks so you can try different mast positions.

Nice job - it'll be interesting if you notice any loss of displacement speed when you cut the tail off at the foil.

Looks user friendly! What are the dims and volume? How much does it weigh? Is thi the board you were drawing and posted a screen shot of a while back?
Select to expand quoteboardsurfr I have yet to see a windfoiler who matches the carving abilities of a decent winger,
I seen a few Windfoilers crave it up just like a winger and with even more style and grace.
I believe the learning curve is much more difficult for the wind foil and I believe this is why so many people kicked it to the curb so quickly.
Most people are sheep and they need to be led by marketing......
I'm not a fan of the mast foot moving closer and closer to the front foot I believe it takes away some of the leverage to carve harder especially in the bigger swell and high winds.
But the beauty about the windfoiling is you can find your own style
It's like a form of Art..
Everybody and their mother is now on a wing down here in the Baja and at home in the Bay Area.
It's a new form of twin tipping in my opinion most people just get good enough so they can get in the way ( Road Boulders ).
Not everybody is infatuated to get there 5 Minutes of Fame on YouTube Just because you don't see it social media doesn't mean it doesn't exist........
But my opinions and usage are different than everybody else.......
