Interesting to see how more aggressive the windfoiler's stance is vs this video from last July. Also, the foiler is using a much smaller wing

I'm jealous of that spot. Looks offshore with a beach that blocks chop, the video says 20-25kts. I run out of room very quickly at race foiling speeds in the flat areas here. So I end up with much more chop/swell.

83cm wide board and very cranked over on a 5.7, 10cm more mast than the SB I run, 370cm2 wing. The sail for the fin is not even a meter bigger at 6.3. He's riding it really well! Going to have to try a narrower board...I can see how the longer mast is making some difference with how high he is riding it.

Amazing. Quite apart from the riders' extraordinary skill, it's hard to believe any mast/fuse connection can handle that kind of pressure. He and his kit must be incredibly balanced or the fuse would just twist off.

Not sure if this is the new version which has a detachable mast/fuse connection where the prior version was bonded. I would think with the pressures top level foilers put on their gear, most top level kit is this robust. That's where all the money we pay for the high modulus CF goes: not only so it doesn't twist off but that it doesn't twist much at all.

If you want to see pics of the connection on the new version of the AFS with the separate fuse: windfoilfan.glissattitude.com/reviews/130

I'd die for a spot like that! Ideal to learn foiling. And yes, the slalom board seems very under powered, a 0.6 m^2 differential and 6.3 with not a white cap around is small, he is clearly loosing momentum here and there. Those are definitely not 20-25 knots conditions, but man the foil rider is good! You can see the foil mast flex, is that ok? Apparently so.

As a side note, I wonder what design trick (?) one could come up to improve the jibe performance of a windsurf ... it is the only place where a foil has an advantage.

That's an interesting question for pros. For me, it's still all issues with the pilot

Good points. The other thing about the foil is that it is likely less tiring, so maybe that will be a factor during racing too

whooopie! Yes, close to 20 knots faster on fins! Including a 38 knots nautical mile!!!!! That is impressive ... I feel so slow ...

Whatever happened to the days when most foilers said they didn't care much about speed?

I'd say that's still the case. Most on here aren't even going to be making the low 20s but that doesn't mean we can't admire the skills of someone who does. Same reason why I don't have a single bit of "speed kit" but like to stalk the GPS/Speedsailing forum next door.

Also, there are some of us who don't care about speed on certain days but do on others. Certainly, a couple of people I know (myself included) would have done a touch better at a recent race if we hadn't spent all winter on freeride gear. No matter, finished at the back but still had fun.

Lastly, we lie. Almost to the last of us, we'll say speed doesn't matter but if sailing beside a good friend, we'll still make sure to be fully sheeted in.

Yeah >20kts so far I want to be on freeride/wave kit. I definitely want to hit higher speeds in wind <20kts and the only limit is myself, but it's looking more and more like the sea states above 20kts are just too scary on a foil for the time being. Lighter wind foiling going fast is still quite pleasant, but maybe that's because I'm just not that fast

Maybe I'll figure out how to keep the pedal down when there's waves 2-3ft that aren't quite aligned with the wind due to the current, but for right now I'd rather just slow down and stick with them like I was wave riding them.

No want for excessive speed on the foil here. I really enjoy the all round speed of foiling, being able to travel upwind/downwind faster than almost every other sail craft (moths and foil race kites aside) on the river is awesome.


I seem to have managed to wrap my head around being air borne, but the thought of foiling out and pitch poling in at speed still scares the crap outta me.

Unaligned 2-3ft & 20-25+ knots is challenging-but that would also be the case on fin slalom. In fact I'd say it's harder on slalom fin than on slalom foil, because in addition to being technical fin slalom is comparatively more physical than foil. So it's all down to technique-so you need more not less time in those conditions :)

You're right. I'm just often the only person out in these spots, due to wind direction. They are in a bay and safer than the gulf or the ocean. Guess I'll stay friendly with the wingers and just tell them to keep an eye on me when I'm trying. And built up to those conditions more.

I'm likely to have a lot more flat water, light wind experience soon now that summer is approaching, so I can probably work on raw speed and improving jibes for a bit.

I asked that question somewhat in jest.

Put two sailors together on the water and you have a race. Happens every time. We all do this. It's in our DNA.

I happen to like speed for foiling because it stays far enough above the stall speed that control is vastly improved. So, what is speed? Most of the time I foil along at about 18 mph with a Moses 950 or i76. I would like to foil at 22-23 mph if I can, but I need a smaller wing to get that. I have smaller wings and will be doing a lot of fun experimenting this coming summer (northern hemi).

By the way, I archive all sessions with a cheap GPS watch that shows speeds and tracks indistinguishable from my GW-60.

You may be able to get there with the Moses 950. I hit ~20mph and lose control on the i76 but it's been awhile.

It's quite easy to hit that with the 900 starboard wing and 115+ fuse in light winds with just a little bit of downwind angle. You can play a bit with the angle if your gps has a live speed readout. Downwind is more relaxed to me with that speed than reaching but I think that'll change with the 105+ and smaller front.

NO doubt foils are getting easier to ride at speed... but it takes SOO much more concentration!

You can see the reef when cruises back over to see if he's ok (and plenty of reef sections under him leading up to the crash)

I've foiled at a popular windsurfing spot that's famously not very deep. However, for foiling, it can be terrifying as the water is not very clear and sometimes you can get close to hitting bottom even though you are over a km from shore. If you feel like you grazed something (probably just sea grass), you look around thinking everything is shallow (which it potentially is).

Same place that I hit what I assume was a crab pot mid jibe (65cm mast), split a wing and cracked the nose of my board.

The closest spot I go to, thankfully, is very deep regardless of the tide, and suitable for almost any wind direction, just gusty and choppy at the top of the bay. There's about 4-6square miles of roaming around before hitting land or getting into unexplored areas (for me) but heavily populated.

Recently I've taken out my windsup to see how far into the city area I can go without hitting something. Some submersed poles and other strange things that drunk people throw in the water, like chairs and tables. I've also seen them when SUPing. So I only push where I'm least likely to hit. Sea life too, including dolphins, rays, and turtles. If not one thing then the other.

There are good water depth charts for around here and if I'm unsure I'll check those, especially at low tide. But those stupid crab pots can always get you.

There was one in particular where I was trying to wavesail and the shorebreak kept me from seeing it until I found myself wrapped in the line. I had a few words to say to the owner.

Yes ... but for some reason I am still dying of envy! (Although my AV Modena 88 is finally arriving next week, same size of the Invictus 88 shown in the the video!)

That is a nice looking board. I would love to have the Modena foil 91.
