WOW
So many answers and tips.
Thank you very much guys!!
Isnt a bigger front wind like 1100 more stabel and user friendly than a 800 wing? Or am i wrong?
My idea is to lift as soon as i can and have stable flights i dont want fast and unstable flights because i have some back problems and the going up and down hiting the water hard will kill my back.
I am aiming to aluminium because i dont want do buy a expensive carbon foil, where i live we have lot of +15knots days so i will be on slalom gear.
So i have to consider a foil with a mast bigger than 75 and what about fuselage?
Thanks for all the help
There are a lot of different factors which determine stability. The farther you have the wings apart make the foil more stable fore-aft (pitch), so that would be height control. Having a wider wingspan would make the foil more stable side to side (roll). Having a wider chord (lower aspect ratio) softens the response of a wing, kind of flattens the powerdelivery bit. A smaller chord makes a wing more "fiery". The 100 and 900 both have a wider span than the 1100, but smaller chord. Based on that the 900 and 1000 wings should be more stable in roll stability, but the 1100 would be more "predictable".
Changing frontwings also slightly changes pitch stability, but that effect would be negligable for the average user. The effect of choosing a bigger or smaller stab is very noticable though, both increasing power and pitch stability with increasing size.
My PWA Racing foil is on the one hand the easiest foil I have to ride, with a wingspan of close to 1m and a fuselage of 110cm it is very stable both in pitch and roll. However the acceleration is imminent, and the acceleration and powerbuildup as a result is very direct.
A starboard supercruiser (i76) for example has way less pitch and roll stability, but a way softer powerdelivery aswell which might make it feel "easier" or more predictable.
In my esperience a wing like the i99 (my F-one 2200cm2 surfwing has a 110cm span) has both the roll stability and softness, but at great expense of responsiveness and speed. Plus the combo with a longer fuselage for pitch stability doesnt really work. (Which could be 'solved' by adding a bigger stab but that would also make the foil more powerful/direct again etc.etc.etc. there's a lot of choices made in the designing process of a foil and its always a compromise)
Do you want a more stable platform ("passive stability"), but with a more direct powerdelivery go for the 900 or 1000, if you want a little less stability but a softer powerdelivery ("dynamic stability") go for the 1100.
