Hi - wonder if anybody's using the i99 with other than slingshot boards (for windfoiling)
I'm thinking of trying it with my SB freeride 150L - with the mast in the 'c' position.

I'm using it on a 2020 JP 190 Pro also in the "C" position. I'm 95KG, 76 YO using Ezzy Cheetahs. Also have SS 76 and 84 wings.

Thank you - are you using the 42 or the 48 rear stabilizer wing? Also - do you feel balanced or are you sailing with backfoot pressure ?

Using the 42 stab. I was going to the 48 but was talked out of it by more experienced foilers. Too so in gybes etc.

A friend used one with the Naish Titan cross-over foil board, worked fine.

If its too lifty, adjust the foil back, and if its not lifty enough adjust the foil forward, either by changing mast/fuselage positions, or if you are using a track mount adjust the foil mast position forward/backwards. If you still need some fine tune adjustment, shim the rear stabiliser, or move you footstraps forward/backwards to suit. It's a pretty docile low speed foil, can't see it being too hard to get working.

I sail an i99 (and 42) in C on a 8ft Hypernut 4in1 with pedastal pushed to front of tracks using the forward bolt holes (so not quite as far forward as poss). I have found it almost impossible to sail i99 on an old formula Board that works fine with i76 in B - but with mast as far back as possible ((106cm vs front tuttle screw), front strap as far back as possible, back foot right at back of board (strapless) and sail no bigger than 5.7, it just about works. Anything else and it just glues itself to the water as you cant balance it with bodyweight (imagine trying to balance standing on top of a seesaw, but with both feet on the same side of the pivot point!).

I think the balance point for the i99 in C is significantly forward of where it is for the i76 in B (which fits with slingshots recommendation not to use it with the Wiz 125) therefore I wont take a chance buying a foil board that doesnt have tracks.

Yep with a JP 155 foil board, because I saw someone also riding with the i99 and JP 155 on a youtube video with no problems. Winter at the moment but the couple of goes I had were great. I use the 42 rear.
