Jesper...What is your min wind for flight on the r810 assuming around 6.5 sail?

Thanks Martin

I have the R810, I am 95kg and I need about a 7kt gust to take off with a sail around 8.0. I had a Pryde V8 flight and I could maybe get flying in 6kts if I found a bit of chop to pump the board down but likewise some days if its choppy it can be harder to unstick the board out of the chop and I would need nearly 8 kts.

I am currently using a 7.8 severne overdrive and with that I can get flying in 7 kts without too much bother.

Sailrepair, thanks, you answered questions I had about the R810 wing and foot-strap position for the new longer fuselage.

As for feeling the height on the old W95, like you I can definitely feel when I am close to breaching, very light flutter feeling, as soon as I feel it I know to lower my height, helpful when cutting across swells/waves.

Actually, I used to be able to feel when I close to breaching on the old Wind95 with F1080 wing, but today on the F770 wing I could not feel anything when close to breaching. Now I did recently notice my rear wing was crooked (left wing tip higher), sanded fuselage flat and added a 0.14" shim on the left side, rear wing is now perfectly level with front wing and my upwind angle increased on the left (270 to 360 degree direction), makes sense rear wing would have made some vibration when it was not aligned with the front wing.

And the F770 wing is working good for me in 13 knots, used to wait until 15 knots, but the F1080 wing was feeling slow today so gave the F770 at try, glad I did. Then went and hit a manatee broadside, stopped the board hard, thought I hit an underwater pylon! No damage to foil or Goya Bolt.

Now if there are whitecaps I take the F770 wing, a lot faster than the F1080, and easier to control when hit by a gust. I now use the F1080 wing with my 8.0 in 10 knots or less.

So here is the thing about using the F770 wing in 11-12 knots, it works great as long as the wind is fairly steady, but if is gusty in the low wind range for that wing then it takes more work/adjustment to stay flying. Had that situation today, so swapped out the F770 for the F1080 and had more relaxing flights in the same conditions.

Nic Dodd has F800 & 700 wings and has used the F800 with small sails, 3.7m. He is fairly light at 70kg. He uses foil boards.

I use the F800-1080 with 6.5m - 8.5m on an AHD Compact 83 foil board, not tried it with smaller sails yet. The distance from the rear screw on the front foot strap to the front bolt on the mast is 57.5cm (measured at the centre line). On my 2 largest fin boards, that measurement is 47.5 & 48cm. I notice Sandmann1221 uses a fin board, with the front strap in the rearmost of the plugs.
Is that the reason for his repeated never using the F1080 in > 12 knots wind? His front strap is comparatively near the foil mast?

I have a f1080 and had no problem using it in up to 30 kts of wind, you just need to use smaller sails than with a smaller wing. Here we get lots of days where the wind can be anything from 15 to 30 kts. Fin sailing is always very stop/start but on the f1080 and a 4.2 or 4.7 you can have a good session.

Same here. No reason not to use the F800 in higher winds. It's very well behaved and even if it's a touch "slow", I prefer that so I can actually play on the swell and not outrun it. Even at my previously heavier 73 kg, I found it to jibe in pretty deep lulls and could keep it flying when I really feel like I shouldn't have. More than once, I've flown it with a 5.4 beside a fins with 8.5s or 9.5s and jibe through when they can't.

PhilUK, the poster you refer to is a bit less experienced and prefers an uncommon set up. imho, that accounts for a large part of his difficulty with the F800 in higher winds.

Exiting a jibe with the wind in the low-mid 20s and chilly (maybe about 8C?). Naish Chopper M (3.7 area that sails like 4.2)
