That's impressive, supuk, particularly in the messy dribble we get round these parts. You make it look easy, but how many take-offs do you blow for every one you make?

Is the leading edge of the foil painted white or is that entrained air I see.
Foote 10'4X34", SIC 17.5 V1 hollow and an EPS one in Hood River. Foote 9'0" x 31", L41 8'8", 18' Speedboard, etc. etc.

That's white paint bill. Catching the wave and geting up is fairly easy, keeping airborne and in trim is the hard part and not poping out is the hard part certainly in the crapy waves and why I'm going to go to the longer mast soon so as to have more room to move

Sweet and impressive foiling! Thanks for sharing. I am also impressed that you are able to embed a facebook video on this forum, is that a new feature? Is there a trick or just paste the video url?

been learning a lot on the takuma foil about what works and what I think could be improved so I think the next step is to build some new wings to go on the mast. The plan is to 3d print them however still waiting patiently for it to arrive. it was supposed to be shipped last week or early this week. its looking like the wing will be have to be split in to 4 parts to get it to fit but that's no real issue.

I have done some re designing and done a modified versions of a clark Y profile which is obviously not designed for water but is a great platform in the air with a that looks about right approach to applying it to the hydrofoil.

I would be really keen to see the profiles used on the go foil and any others to see what they are using front and rear. are they using the same section on the tail in reverse?

I had a load of small blocks of foam that were only good for prone boards so thought I would stick two together and do another test board a bit different to the last but still with the big chined rails.

I think you can start with the rear at zero, based on my conversation with a guy who's built a few.  Is your front wing going under the fuselage?  That's the most common setup.  My foil is on hold because I might see a few in a few weeks in Hatteras and get some ideas, and my ice just went out and I won't be riding it (swimming a lot) any time soon!  Hatteras is also too shallow in many spots.  On lighter days I'll suppin the ocean side.

Hello,just tried my DIM home foil today,  amzing but lift is very brutal. understood rear wing/stabilizer is set to downward lift ( flat face/intrado up/extrado down) with angle abt 2° downwards, am I right? did someone tried rear wing with extrado up same as main wing ? in that/any  case which angle? i can reverse rear wing or adjust angle with shims. thanks in advance.

Wow, I just realized how challenging it sounds to diy a foil.  Learning to foil has been super challenging for me, and the thought of trying make my my own and learn at the same time sounds Herculean.

You guys are legends!   

Super impressed with everyone who is making their own foil.  I look forward to seeing where you take it, and believe it can only grow and improve all of foil surfing.   Thanks!

I would try doing one or the other ether the reversed rear wing or 2deg positive insadance. You are basically doubling up on the correction. If it's your first time foiling the lift can seam brutal at first. Have a read on all the tips and vids out there. The key is learn how to keep the foil down rather than up at first

more negative incidence on the back foil= more stable in just about every aspect, even turning.
supuk that wing is sexual, heres how ive been running mine for the last few goes

New foil board is getting glasses but think I may keep it under raps till it's done. I have also been working on some install kits to make it a lot easier to install the double boxes into the board. The final ones will probably get made in P.E.T
I think this is a great idea, are you planning to sell this?

Yes I think I will cut a few and see if there is any interest. I have just got a few different types of HD foam to try to see what's going to work best and keep the cost as low as posable.

I definitely would be interested in at least 2.

I will try and cut a few more of the inserts out when I have some more material as I need a bunch to convert my other boards.

Got the new board cut, not all that prity but at the moment it's function over form.I also made myself a little foil kite board last week from a block of scrap foam and with the sup extra wide glass it only used about 3m

Was out for the first time on the new board, still learning lots about what exactly we need in a foil board it has been very interesting trying all these designs and its a lot more complex than most would think. Once again I cant under state how critical the foil positioning is and how much difference it make. The first few waves yesterday on the new board and I was fighting to keep the nose down with soooooo much front foot pressure so I went in and slid the mast back 2cm and added a 2mm shim under the back and the next wave it felt like a different board. Back out today I hope with another modification to try so we shall see how that helps. I have a ton of other ideas to try when I can get a little more time and cash to work on them.

sorry for the shit quality I need to figure how to download and upload them better from my camera to phone to youtube
