Mind blown. 

Imagine a retractable foil so you don’t carry the drag upwind but once you reach a downwind leg, deploy that thing and off you go.  This could change a lot of things.

I emailed Alex to see if we could get some full images of his foil.  He wrote:

The foil is on back order already for two months and growing and as you can imagine, we are holding the pics of the new downwind/wave foil under wraps for a little while longer to try to keep the competition at bay.

I'm pretty sure it looks very similar to the foils that I've been seeing on WS boards and kite boards, which are all very similar with various tweaks here and there.

I doubt it. That is a very very old style foil. The wings are extremely different these days. The wing in that images is very unstable compared to the modern wings.
Edit: I might have misunderstood that you thought the image was how the foil would look....

Someone said it is hard to ride foils...I would say I disagree...I was upwind in less than 30 mins on my kite foil. This is way way back tho, and now they are even easier to ride.

I'm a little disappointed the Naish crew didn't resurrect last years Penetrator board for the foil video, seeing that thing hovering along would have been spectacular.

I'm surrounded by foils these days, and I've seen maybe 50 different configurations that are all still used, so when I say a "tweaks here or there", it's like which fin do you use or like the best?,,,,,,,, many answers, none of them wrong.
For a look at the variety, just do an image search for windsurfing or kiting foils, there are hundreds of designs but the basic layout of the foil, as a whole, is pretty similar from one to the next.  That's was all I was referring to. 
I've got one friend that got a broken foil (wings busted off) so he made new wings out of plywood, and the damn thing works amazingly well.
You can even get foils with different wings for different conditions.
It takes a quiver to do that.

Sooooo, whose the guy who thought to put a giant ass fin on the bottom of a board and try and figure out what that could do? I can see how it would have started with sails on boards.....Whoa....and then to go and try without a sail.......both really amazing I think.

Apparently they did try, but had a very very hard time getting it up.

I've foiled behind a ski.  It only takes 6-7 mph for lift.  Even a crap paddler like me can burst to that speed.  Pitch control was sensitive when I did it but as some have said, things have improved.

My question is about depth.  Obviously if you go over a shallow reef, we have many, you're going to hit if the wind lightens and you lose lift.  Or even coming into shore for that matter.  Kai had a ski along side for filming him and also to pick him up when he needed to go in.  That's not really workable for most people.

The answer might be an easily removable foil you can take off, carry out to deep water, mount onto the bottom and take off before you approach the shallows.  But that's not what this is.  So it has a ways to go

They had it up for 4 hours and had to seek medical advice...

How much wind and bump to make the foil work on a real, 14' + board? Why is he using such a short board?

And what if the wind dies, or shifts mid run?  Is the whole contraption paddleable to get back to shore, without wind / bump on the back?


The less board the better. The foiling sailboat Mirabaud LX has no hull to speak of. Once foiling the board doesn't do much.

I wonder if we will get to the stage where us flatwaterers can pump a board around the fjord with very little paddle.

Yeah for me this is the coolest idea ever and seems like a really fun way to have screaming DW runs.

There are guys who kite foil surf and windsurf foil near my house as well Artemis has a little double foil sailboat so I'm pretty confident that my area is perfect for foil DW SUP runs.

I already emailed Alex and told him I want one.  Super stoked on the possibilities!   ;D
Aloha, I welcome and appreciate all responses of positivity and good feeling.

I plan to build a foiled DW board this summer, different design in mind. I plan to use the board as the foil fuselage.  Retractable front foil, shorter rear foil--a little deeper than a standard fin.
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.

Until I see a side-by-side GPS'ed DW run between a foiled and non-foiled board I'm skeptical. The cutaway shot of the foil at :05 could have been a staged with something different. Regardless I would love to see it happen and even if it's something I could use 5 or 6 days a year here on the mainland it would be worth it.  However you need to really work out the drop in take out logistics due to the draft. I'd rather go sans-leash too so I probably need an escort too.  Hey this is getting expensive !!

I asked Alex how this might work for other sports as well.  He replied:

I Have not tried it on the windsurfer yet but it might work. But I think it is better for SUP and beginner kite foiler

The other Go Foil products look to be modular, so I am wondering if this might have multi sport possibilities.  That would make it pretty interesting.
