Wow Nils, a brilliant explanation. You might be the first to go into so much detail. Nice.

Hi Nils Thanks for the explanation. However if I use the reccomendation of the Ezzy Cross it states: - Foiling requires a flatter sail because you sail closer to the apparent wind. This means you will downhaul and outhaul more when you are rigging for foiling, compared to finsurfing That is quite the opposite. Its a combined sail for fin with regular downhaul and foil with more downhaul Matter of trying and your way of sailing I guess. Absolute racing speed, freeride or fun cruising….

are u kidding me, i just searched yesterday for exactly a video like this, THX Nils

Much appreciated, thank you! Heading out for the first time on a foil in a few days.

Clear explanation. Just what I need. I will do the same with my Ezzy Cheetah 7.0 next time foiling

Makes sense! Thank you for the tips!

Great tips,thanks a lot

Nice video! I am also using a ac-one 7.1 in foiling. I will try you set-up next time.

Thx great video

Thanks a lot that Video really helped me understanding the difference!!!

Tnx, very useful.

Thanks for all the info and tips. Manufactures/shops would want to sell you a new full quiver of sails.

I presume the advice works mainly with cambered sails? Becase on non-camber with not enough downhaul it most likely will not rotate.

Today ride foil with slalom sail with less downhaul. It works very well, thanks a lot. But the sail became dificult to cam. Worried demage battents

Hi Nil What changes do you make to the tuning when the wind picks up and you don’t want to change down?

Is there no risk to break some camber batten when you rotate the profile if you rig the sail like this? (which it is surely not designed for in the first place) 🤔

Using the F1E for two years now. I can tell you, you do NOT want to have maximum profile. While being hella stable, this slows you down considerably while going upwind or chasing speed records. Good foil sails are still stable while minimizing drag by improving airflow over the sail. For slalom, fin sails are good. For extremely light winds or upwind courses, foil sails are the way to go. Edit: A great indicator for your sail “stalling” (wind does not move through it perfectly) is, when you hear a loud, constant swooosh sound. Also the F1E is far from a perfect foil sail. But you can come close with a good trim.

If you trim your camber sail like that, how is the rotation when jibing?

Hi, do you recommend the Duotone E_Pace, as the producer recommended it for fin and foil? Also, what do you think is the ideal size for my board, JP Frefoil 115L, I weigh 80kg and the wind is between 6-10kt? Should I go for 6.2 / 6.6 / 7.3 / 7.8? the foil could be 1300 - 1700cm2

Less downhaul could result in cambers popping of the mast due to camber over-bending

How tall are you Nils?

Hmmmm. On foil sails you want to get the sail really flat with a lot of outhaul tension ... On regular sails it would be the total opposite ? PS : ok get your explanation right after my comm haha PS 2 : that is very short harness lines buddy
