Was out for my first foil. Was on a sb formula 162 and a np rs:one AL foil, 7.5m sail.

Mast foot was almost all the way back (covering the serial #) I find with this board in perticular you need took keep the mast foot back to keep the nose from sticking. I'm light 65kg. Had a few decent fights in light wind with one crash. around 6-10 knots. With foiling there seems to be even more tuning then windsurfing. Had trouble at times keeping enough weight in the back to get the foil to lift probably some poor foil nubbie technique. But is there a standard distance foiling boards keep the mast foot from the edge of the fin box for maximum control and lift. I will measure mine to compare, since i use a non foil board is the track in a weird position comparied to dedicated foiling boards?

Seems that a good ball park figure is 110cm from the front tuttle bolt and then adjust either + or - as required

Yep, on my f162 the distance from where the mast track starts to where the first fin bolt is is 108cm.
Will hopefully be out on the water this weekend.

Need to play with foot positioning. May try without back strap. Wounder if moving the front strap more inboard will keep my weight to far forward. I guess I will not know until I try.

This is my first post here, I'm new the forums but have been foiling since May.

Like you, I was having issues trying to get foiling and weight distribution. I was told to move the straps around in one hole increments rearward from the front to find the sweet spot. It makes a big difference to move that front strap back first.

Also, I'm having more success by having removed the rear straps all together. I find that my rear feet are all around the rear of the board. Until I get better technique in general I won't put the rear straps back on yet.

I have gone through this on Formula. I don't recommend removing back strap on Formula board. You want your foot in and on the rail as much as possible. U will be pushing. Get your back foot in right after front. Get more speed now. Your front will come up and u will have lots of control. U just need speed. So front strap all way forward. Back all way back. Mast tweaked. But to back. Shorten you harness lines and make sure u use them as it will be easier to keep nose down. Lots of stability with formula, it's made to foil.
Good sailing and hope this helps!

There is a lot more tuning compared to normal windsurfing as there are many more degrees of freedom involved. There is a good thread on here about the Pryde AL foil, probably worth a read.

From what you describe you need more rear stabiliser trim = more lift. This reduces back foot loading, something I found was quite high on the Pryde:Al when I used one. So washer under the front bolt on the rear stab and give it a whirl.

I have done many of the things as mentioned. I have received advice to keep my back lag straight in the back strap. When I bend it too much it seems way less stable. I have gone with the washer in the front of the rear stabilizer. For more lift and more control.
Wind seems light this weekend so I think I will try my 9.9 for the first time with the foil and see if i can get up in 7kts. I have only been using a 7.5 so far.

I have sown two mast protectors together to help during my first flights, no nose damage through about 6 sessions... works great so far.
