Why do you say the 99 needs a board with track ? Wing has to be moved further forward than what the switch fuselage allows ?

Hi

Thanks Paducah. Well the RS:one foil works, but it requires so much speed to lift.... In the meantime, read a few other post on the forum which said the same thing. In general, this foil lacks of lift (small wing) and is very back foot heavy. Not really a light wind option. And fuselage is on the short side.


So I will change for a Moses or a Slingshot.The big question is which wing(s) should I get.

The 790/I76 or the 873/I84... or both.

Any thoughts ?

I have or had all 4 infinity wings. If you are a big dude I would get the 84 (unless you plan to get the 99 in the future). But if you are a regular dude, who knows how to pump the sail, I would recommend the 76 as it has the largest wind range of all the infinitys (IMHO). Yes you will miss some of the early planning of the 84, but this means you need to schlog a little further to the wind-line or wait a bit more for the wind to come up.

I personally don't feel the slight early foiling of the 84 offsets the loss of maximum speed relative to the 76, unless you live in a chronic lightwind area (meaning your smallest sail for windsurfing is 7.0), but If you want to push the light wind envelope you should probably get the 99 (99 and 76 is a great combo), but the 99 needs a board with tracks.

I'm with thedoor on this one. The 76 is already double the area of your current wing. I'm about 5kg less than you and I was foiling all about yesterday in about 11-18 kts with a 4.7 and 1100 wing. Speed/lack of drag can be as important as shear area in light air. A foil that accelerates, generating apparent wind, and can glide through lulls can be very effective. The big guys need more area - no doubt, but for smaller people, a big wing is just a lot to drag through the water. I've ridden briefly the 76 and 84 and, for me, I prefer smaller, less draggy wings. They are good wings to be sure and you won't go wrong something like the 76 or Moses 790 but the additional benefit of the 84 is marginal, imho. Of course, it depends on your budget. I'm the last person to say anyone else has too much stuff.

Effective pumping solves a lot of light wind problems as does learning to jibe in the puffs.

Sounds good!

Then I will go for the Moses 790 /Vento kit

Do you put the Moses 1100 it in the same basket as the as the I84 ?

Or would it make sense to complement the 790. Moses wing are reasonably priced... I am thinking it might help further the learning, and allow for a couple more sessions. Moses wings are lower cost than Slingshot, so I could possibly afford to buy 2 wings upfront.

From appearances (I have no direct knowledge), the 873 is the analog to the i84. The 1100 is slightly higher aspect so probably just a touch faster while the 873/i84 will turn just a touch better. The Sailworks comparison sheet was helpful in confirming these speculations: www.sailworks.com/documents/Windfoil_Wing_Compatibility_Comparison_Chart.pdf

Hello CoreAS,

happy Easter, what the distance between the first bolt of the Tuttle and your mast plate? on the video it look like you move fully back compare to the baseline of 107cm from slingshot

Yes generally it needs to be moved further forward than the 76 and 84. Or else you will need to move your mast base and possibly your straps further back for it to work with the same board. That was my experience but some on this forum can make it work without a track

You don't need a board with tracks! We have 6 locals here that use the i99 all with tuttle box.

But can you comfortably jibe it? For going straight everything sort of works, its in the turns where you notice whether the balance is right.

Did you not watch the video? They're 2 gybes in very light wind.

Tracks? Doesn't it also depend on weight of the rider? For a 70kg rider the front foot pressure is different than a 100kg rider. If the wing is balanced for 100kg; does that imply it'll be balanced for a 70kg rider???

I reckon heavier riders can exert a greater leverage over the wing with their weight shift than lighter riders. So you might be onto something.

I am extremely new at this foiling business, but what I can say is, the i84 is plenty fast for me. I was zipping around on it yesterday hooked in the harness and unhooked. I found when I was hooked in, I was achieving much higher speeds than being unhooked. To me, being up on foil at the same speed on a slapper feels faster on foil. So when I was on the i84 yesterday, it felt like I was hitting speeds of around 20-24 mph, but was realistically around 14 mph max speed. I'm glad I didn't get the i76. I think i76 offers more speed than I want at least for now. I have lots to learn and feel out with the i84, and I don't see myself growing out of it anytime soon. The i84 offers plenty of speed. I'm 175 pounds, 5'11", so I'm not a huge guy and I don't feel that the i84 is too much wing for me.

I was hoping to see you uphaul.... next time don't edit that out!!!

Coreas, your vids are awesome and they have helped me learn. Thanks for what you do! Launching, retrieving and uphauling are the basics that are needed every time one goes out. Videos are often full of advanced moves like foiling gybes and 360's and that is awesome and entertaining! I know my beginning stages could have been shortened with more footage of the basics. I am starting to watch video's on windsurfing now as opposed to windfoiling and it is really helping me find some answers. I don't know why that took me so long to figure out. There are still a bunch of basic but unique to windfoil skills that are not well documented. My wife grabs some clips here and there but it will take forever for me to put something together at this rate, plus most of her footage is of my gybes!

JonnyWindsurf, I bet you could uphaul on 125L but why would you want to! I love how windsurfing companys think we are all small fit pros. I went from a 120l board to a 180l board and my foiling got a lot more fun!

Interesting!

Why is it better in your opinion ?
