Farlo Once upon a time you could adjust fin in the track and people were debating about the best position for planning vs. speed, etc. Then came the conic box, Tuttle box, power box and the fin was set once for all. What I've heard but never practiced is that moving the mast back helps lifting the board from water => higher speed, fly over chops; mast ahead => early planning, better upwind. This is because you balance pressure differently between back and front feet. Now for a given board there is probably one neutral mast position suitable for all sails, which may vary from one rider to another. Competitors are more demanding, I agree. Let's hear...

Mast track tuning.

Thanks guys for your comments till so far.
Farlo; I do the same things with my sail and fin.I only change position (forward) to have more control f.e.
Unregistered guest: how do you change things to have more control or early planning?( not changing finsize,boomheight)
Coachg:I agree,that the settings in which you have control (=confidence) are the best.
The example of the Futura is not clear to me.The 93l is the same board as the 133l. They differs
in length and volume.In making a short calculation they have almost the same position in the track.(in regards till the length).So I think there are methods to calculate the position for the
The reason for my question is: If I am on the beach I see different settings with the same sailsize and finsize. I believe that if we four are on the same spot with the same board,
same sail,fin, we would have different settings.
Is there maybe a competition windsurfer for some comments?

COACHG The recommended mast track position should be suitable for all sail sizes that fit that particular board’s range. So for normal sailing in a given board’s range, no, you shouldn’t have to move the track. Obviously though as sails get smaller or larger the track will be more forward of more back. For example, the 93 liter Futura has a mast track range of 127-140 cm off the tail while the 133 liter Futura has a mast track range of 130-145 cm off the tail. So if your mast track is all the way forward on both boards then the difference is actually 5 cm. Of course the sail ranges for both boards is quite different.

As for what setting is the fastest? That is easy and has already been answered. It is the setting that you are most comfortable with because in the end you are faster when you are confident.

Farlo As I'm lighter I stick it a bit backward but not much. I have been using sails from 3.7 to 7.8 on different boards with consistent footstraps/mast base position. Some older boards have mast track way forward, so I have to make compromise with the spacing, but then I can switch sail or board without changing any setting (excepted harness lines). Changing fin seems to have much more influence on planning/speed/control.

Unregistered I`m with Farlo on this !

I stick my mast track at front in every boarrd I`ve got .Have done so for past 10 years.
Occasionaly experiment moving it back but never found any benefits only drawbacks. (later planing; bouncy nose)

Thought I was the only heathen !!!

(I justify it saying at 100k (+) all my board needs best early planing .

Listened to some fool in Feurte telling me to move track back for speed. I went back out and found I was 3 to 5 knots down; pushed it back to front and sailed past the "fool".

Even leave it at front with quite small sails !!!

Sorry !!!!!

Its one less thing to worry about adjusting ; for me anyway.

Seems a different issue for mates though; they all move it back with smaller sails !!! Which makes sense but doesn`t work fore me !!!

Farlo You may not believe it, but I never change the mast base position on my boards, whathever the sail or fin size (occasionaly I will move harness lines). Moreover I tend to copy/paste footstraps & mast base spacing from one board to another. OK I'm not the fastest guy out, but I never feel unbalanced. This stands for freeride/freerace not slalom/speed/competition.

Mast track tuning.

My question is: Is the recommended position suitable for all sailsizes.
What is the effect of the fin size on this position?
