Sailboard Hydrofoiling

Seems this is the buzz talk in the windsurf world for 2016. 

Some people are calling it "windfoiling", but on a Danish forum they complained that this term is NOT clear enough. Why would kitefoiling NOT be windfoiling ? Can we call it windsurf foiling? Windsurf is a term that ideally refers to surfing using wind. As such, most of us are doing sailboarding. And so ... sailboarding with a foil s/b called what ? Danish forum suggested sailboard hydrofoiling or SBHF 

The first SBHF that I became aware of was the AHD AFS-1 and that was a years ago.


It is somewhat unique with the hole in the nose and the wide tail ...

One thing I found interesting is, the wings of the foil are held on by the plugs at the end, which have a LONG bolt/screw going into the middle.

Why this never caught on , is beyond me...

Another French company called the Horue seemed to get their name out there . My joke is they succeeded due to interspersing bikinis in their videos ...



The hydrofoil that caught my eye was the iFoil:




When I first saw this model, it felt like it made the most sense. Why bother trying to balance the whole apparatus on the single point at the back ?? With a foil in the front, you are more balanced and have more options ... in terms of body placement , etc ...

Of course there are other hydrofoil companies ... ketosfoil, foilever, kerfoils, lokefoil, etc
Most of these are names I have NOT heard before and MANY seem to come out of France !!

Foils still cost about $1000 and companies like AHD & Horue sell boards to go with foils.
Otherwise , it seems a slalom board of about 80 cm width and naturally tuttle fin  box  is suggested.

I will NOT get into the technical details of the foils. It is difficult enough to understand fin concepts. Suffice it to say hydrofoils for sailboards are larger than those for kiters and the bottom looks like an aeroplane.  There are MANY models and some adjustment is available on them - like angle,  etc - depending on the model...

There is buzz about this on almost all the windsurf forums...
Here is some discussion from iwindsurf and a video of some people starting out ...

and naturally there are some on facebook too - here is a smooth jibe:

What?
You want MORE bikinis ?
Shame on you ...



My joke - this s/b called SOBHF, as in a jealous "look @ that SOB hydrofoiling"

The one that surprised me (and NOT just me) is the video of Kai Lenny (who is now 22 !!) hydrofoiling "downwind" on a SUP and making it look easy. He and Robbie Naish can make anything look easy - AND cool !!



And Exocet is working on a two foil board - NOT released YET ...



There are TWO major concerns with foiling and I am NOT even going to mention price, risk of danger with large knives under water, etc.

Firstly the obvious one is that foils are quite long and as such need deep water to start, maintain and need to be wary of sandbanks in case you are not up in the air ...

The one I kind of forgot about, but have read about is weeds. Is it going to be necessary to develop weed foils ??  At the cost of one of these, there is no way people are going to have two !!

Even for my wide freeride JP SLW92, I have purchased a Lessacher 42 cm fin  in order to see if it is not possible to avoid weeds AND ride with a shorter fin ...

Knew I had once seen pics of the earlier BIG windsurf hydrofoils .. Well, I stumbled upon a video which seems to be narated in Dutch, but seems fairly clear. Notice: NO footstraps ...



and here is a TV discussion or Rich Miller's 1995 hydrofoil:



It seems that over thirty(30) years ago a company HARKEN made foils for windsurfers:



Addendum: Just found out recently that AA / A ² / Antoine Albeau may have been foiling / hydro-foiling on windsurfer boards for the last ten (10) years !! That may be the reason why he won the 2016 PWA foil races !! If the following link still works,, go to about 5:30

http://livestream.com/accounts/9351246/events/6423750/videos/137826595

SBHF looks like it here to stay - even if fins/foils cost OVER $2000 !!
reminder: SBHF = sailboard hydrofoiling ...

more n more videos and discussions coming  out:



Kite foil companies are realising the potential and are building foils for windsurfers now !!



and some are getting REALLY confident !!



After some careful deliberation, I came up with some criteria:

1) deep tuttle and thus NO need for an insert
2) with a base plate so as NOT to stress the fin box
3) alloy in order to save some serious $$$
4) ideally able to change position or angle
5) different lengths and foils available

So far, I have come up with this one:


Looks like even in Montreal we may start to see some windfoils !!



Finally an article with some decent comparing. Vour parlez francais n'est-ce pas ??

or try the google translated version ??

https://translate.google.ca/translate?hl=en&sl=fr&u=https://www.windsurf.boutique/actus/comparatifs-windfoils.html&prev=search

and now they have a motorized foil called an e-foil:



As discussed in the comments, on some forums and seems to have been attempted years ago... some people are adding a blade/foil to the fin which is parallel to the base of the board:


Some people are still on the fence - is this a FAD or even too dangerous. Kite boarding is definitely more dangerous than windsurfing and yet it is increasing in popularity. Ironically some beaches have banned kiting in recent years... If people get hurt often enough with foils, will they be banned too ?? Locally in Montreal, more and more kiters are experimenting with foils and a buddy of mine - lost his and it NEVER turned up again. Nice loss of about $3000 and I felt bad when I lost my GoPro ...

Update: September 2017 ...

I am SURE you have all heard about the GREAT North American one and ONLY windsurf magazine called WindSurfing Now ?? Well, guess what the latest issue highlighted ?? You guessed it - Wind Foiling !! It may not be obvious from the cover, but KP/Kevin Pritchard is actually on a foil.


Since he is sponsored by SB/Starboard, I would have expected him to be using a SB foil as well, but he was using an MFC foil. Well, they are on Maui too and so , I imagine it was more accessible and he actually called them for some technical questions, when KP did NOT tighten all the bolts properly !! However, on the back of the magazine, there was a SB foil pictured ... Here is a pic of one from the web  

Okay, there is an article with KP foiling @ Whistler, BC , picture of Tyson Poor jumping a foil, article with Robbie Naish on a foil, images of foils (SB, NP, Slingshot, Naish, MFC and even BIC)  and now foil boards (SB, JP 4 the NP, Slingshot, Naish, Gecko, Techno and Goya + Simmer too), BUT what really got me was - there were foil sails too !!

Since most of the companies have been mentioned, but not his one yet ... Here is the SailWorks Flyer with both the BIG boys on foils !!


What i find interesting are the sail features ... Depth in the sail, soft tension, cambers for profile, less sail twist and a forward draft. Hey, that almost sounds like a smaller version of a longboard sail !! They will only be making them as large as 7.0 m² because foiling just seems to need less of a sail. However, when racing , AA has been known to use 8.x sails. That Flyer in an 8.x size would probably be just great on my longboards !!! It is difficult to find readily available longboard sails in North America .... (don't quote me on that - cuz I am sure someone will bite my head off).

The magazine had plenty of other great articles. The one that caught me was Levi Siver sailboarding down a snowy mountain with a custom "snowboard"/windsurf board ...

So, if you are not subscribed to WindSurfing Now, you better get to it !!

I like this discussion here:

Ultimate Wind Foiling Guide: Best Gear for Learning from Big Winds on Vimeo.

what about this one ? looks like a windfoil with a kitewing or perhaps inflatable sail like iRig ??


Check out the on-line windfoil academy !! http://www.foil-academy.com/

some good stuff here, in case i did not put this up yet ...

https://shop.wind-nc.com/blogs/news/windsurfing-hydro-foil-faq-buyers-guide-tips-comparison-info

frpgear are actually selling what I will call the mini-foil .. it is 12 inches / 30 cm long and 14 inch / 35 cm wing span with a light weight of 0.9 lbs / 0.4 kgs. it is supposed to generate enough lift to relieve 50 pounds of weight / 22.7 kgs. this one is slated to work best with narrow boards - rather than wider boards like the full foils. i am in contact with them for a powerbox version in order to try it on a longboard and the Shark 145 😊


Asked on iwindsurf about these quasi-foils and got the following !!

"Those were a bad idea 28 years ago and they still are. "

Foil boards are around $3000 and wind foils around $2000 and now there are windfoil sails too.
The industry is disappointing me with these rich boy toys so much, I truly feel it is time to go back to basics and perhaps go for a KONA ONE and sell everything else. Just forget about trying to keep up.

asked on iwindsurf if i needed re-enforced fin box and if better with JP SLW92 or the AHD SL2 132.
gregnw44 had a GR8 answer !!

Joe, 
Look for an old Starboard Go board, late 90's to mid 2000's. There's gotta be one of those gathering dust in someone's garage up in your area. They have a deep Tutle box... are strong enough (but still light enough)... and have added length, which means WAY easier "splash-downs" from foil-out's. And easy touch n go's. We all do lots of that stuff, while learning. 

I've foiled a bit on 2 different Go boards... and a bit more on my formula board. All work fine. But I have a friend who's foiled for more than 100 miles in the Gorge, on his Go board. He has learned fast and done very well on it. 

Anyway, I also know many people using other formula board and big slalom boards. All work fine, and no damage yet to stock tutle boxes. Although, I've heard stories of stock tutle boxes eventually having cracks for some people... but so far, this seems rare. People in the business tell me, "use whatever you have with a deep T box... if or when, some day, you get a crack in it... then sure, get it re-enforced". 
I also like the LP (what I have) and the Slingshot (what some friends have) because they have a flange which distributes load on the bottom of the board. This will also make a stock Deep T finbox board last longer. However, I also have friend's with "no flange" foil masts... and their boards are ok so far. 
Conclusion - You do NOT need a special board or special sails. You're on flat water, just looking for a little extra fun in 10-20 mph wind. You and I are bigger than many. Neither one of us are going to foil in waves. So all you need is your SLW board, which would be great... or an old Go board, which would be a little better for you, cause it's longer. 
So after you're using and learning with that, for a while. If you "really get into it" or your deep T box cracks... you can get it fixed and beefed up... or get a ready made foil board. And then you can add special sails as well. 
Of course, if you want to invest big $ right away, you can. But for guys like you and me (frugal) it's not needed, to start having a really fun time.
 

just discovered this link which seems to have an extensive list of the different windfoils on the market now - too bad it is not also a review ...

https://www.windfoilzone.com/windfoil-guide

that was a good source of information in order for me to be able to create this spreadsheet:

summary of some foil boards --> average volume of 133 liters, width of 78 cm and length 226 cm
however, the forum discussions suggest longer board with more width and shorter mast on the foil for an easier start ,,,

  1. I'm wondering if anyone is selling foils in Canada? I'd love to try it.

    1. happened to speak to Bruno of 2-rad on the subject and he does not seem interested @ all. Will ask Yvan and René of auventfou about the AHD AFS-1.

      Delete
    2. auventfou has confirmed that they can supply AFS-1 board and foil on special order, but be prepared to pay about $7000 !!!

      Delete
    3. then again a FULL slalom kit costs about $10,000 too !!! has it become a sport for the rich ? How did I get here ??

      Delete
    4. OK, may be a while till I buy one! Thanks for the info.

    5. fins don't cost that much to ship - maybe foils too. Guess it will hit States before Canada. My current concern is "re-enforced fin box" and angle of foil on a typical board - boards made for this seem to have box further up AND re-enforced !! back to the $7000 question ?? perhaps JP/NP combo will be less ? NOT on their website YET

    6. Check out tillo-international.com from Miami, there're few others including jp, starboard. Foil prices from $700-2,500 depends on quality and materials. You can use it on the board over 80cm wide with solid deep title box, or get special foiling board $2000 or so.
      Advantage, need 2m2 smaller sail

    7. I did buy a slingshot foil and am having fun with it: http://windsurfing-en-provence.blogspot.ca/2017/07/another-foil-run-on-video.html
      Check out the blog posts from May and early June for more about the setup.

  3. There is also a "semi"-foil idea coming from polish virus-fins.Custom made of carbon they suppose to combine the certain board feeling with earlier planning ability and foil aroma when speeding up. https://www.facebook.com/theviruscarbon/photos/a.1707107396242761.1073741828.1706278012992366/1947173382236160/?type=3&theater
