Ummmmmm.... I think at one time this was the accepted way to look
at this, but with wider boards, better, faster rockerlines, and
improved stability in sails, it's no longer this simple.
> The fore part of the fin must be straight up the back of the rear
Not anymore. One the wide race boards, and AVS boards, I often find
my back foot to be nearly over the center of the fin.
On 90-120 liter free ride boards, it still may be true to some degree,
but you will give up both performance (speed) and maneuverability
if you move the footstraps every time you move the fin.
Moving the fin forward (even a little under your foot) will loosen
the board up and allow more slashy turning, and a bit better in
Moving the fin back can be used to prevent spinout, increase overall
speed potential, and improve upwind sailing.
This contradicts what someone else has said, but I've always found
the the further away from the fin you put the mast foot, the better
the upwind performance (except in the case of the new very wide
boards, huge (50 cm +) fins, and shorter planing flats.
You cannot afford to lower the nose and push the rocker into the
water just to improve upwind sailing performance. You loose too much
speed overall, and with the proper fin and technique, you can go
extremely high with the fin and footstraps all the way back and the
mast foot positioned to keep the board at the best planing attitiude
for overall speed.

I agree that for novices the footstraps need to be forward, but not
necessarily the fin also. This will make the board more twitchy
and less easy to maintian directional control.
> If you are expert it's the opposite.
Gotta disagree here. Most experts have a definite relationship
that they want between the fin, footstraps, and mast foot.
They measure this, and have been known to have footstrap plugs
added, mast boxes moved, etc to ensure that they get the set up
that feels right for them.
Also, expert sailors will move the fin a little to compensate for
water conditions, the type of sailing they are doing (wave/B&J/slalom/
racing, the fin style they are using, etc, but they rarely move the
footstraps once they get them where the board works best for them.
Well, not quite so easy, but you make a good point about having the
leading edge of the fin "project" up to the back of the rear footstrap.
In most cases, when you aren't sure what the relatiionship should be,
this is excellent advice on a good starting point.
But it differs with different boards, fins, sea conditions, sail sizes,
so experimentation is also good.
