What year did the manufacturers start moving back the mast track.  Was
Starboard the first?

He asked because he wants to know.

Because I need to replace a very old high wind board but I will
probably buy used.

Do you want the track forward or back?

If want an old school high wind/wave board you should be looking were
the back of the mast track measures 51" to the tail.

Hi Peter,
I'm not positive, but my educated guess would be right around
1998-1999.
That's when the first shorter, but wider at the back, race slalom
boards arrived (Starboard W75 flapper board was a good example but
there were some other custom race boards that Ken Winner and Eric
Voight designed) .
Around 1999-2000 the width started moving back on a lot of production
boards, but I'm not sure that Starboard was first to do this.
Previously (around 1992-1995) we had the "no nose" era and the mast
slots seemed to move a little to the back, but not as far as the modern
2000 and later boards.
Mast slot position moved back more quickly with the introduction of the
Starboard Formula 155 (1999-2000) as the width and volume suddenly was
well behind the mast foot.
As mast track position in boards changed sails began to change as well
to suit the newer design boards.
What board do you have, and what are you thinking of replacing it with?
Starboard was amoung the first to introduce shorter wider at the back
slalom boards (the early Carve boards) so they were probably amoung the
first to really embrace the width back, new rockerline concepts that
make the shorter slalom boards work.
Hope this helps,

Which came first the chicken or the egg?  Actually, I think the boards
changed to fit better with the loose leech technology in sails.  The
luff sleeves also became tighter so mast diameters shrank, didn't they?
 I think, though, that the mast tracks were brought back in the early
90's  I used to own a glass board from the late 80's.  When I compared
it to three boards I have from around '93-'96, the track was seriously
set forward.  However, the back position on the old board did line up
with the forward on the early '90's boards as I remember.  Since long
adjustable mast tracks were introduced and popular in that era, they
could accomodate both old and new sails.  You may want to find out when
the first loose leech was developed and who was responsible.  This
innovation was slow to be adapted by all sailmakers so there's an
overlap in dates. The mini-batten didn't become common until after the
loose leech had been in regular use.  It's rather easy to pick out the
mini-battens to identify a sail cut for a lot of downhaul.  However,
you can't put a lot of downhaul in many sails that don't have the
mini's and optain a loose leech.  Some you can.  I met a guy one the
beach once who had been sold a downhaul crank so that he could loosen a
leech on sails that didn't have the feature as part of their design.
Duh?

I found old starboard, F2 and mistral boards.  The mistral is an older
stinger (has a custom look to it) the Starboard is a wave 253 or
something similar, and I do not recall what the F2 was.

All of them were made between 1999 and 2000.  I will be replacing the
challenge flex, which is starting to fall apart.  I have older sails
but will be phasing them out over the winter/spring, so I want a board
that will be happy no matter what sail is on it.

Thanks

Jeeze Chuckles, no attempt to disguise yourself at all?

Sails became more stable, part of the physics required for this moved the
COE farther forward in the sail, and since it didn't shift back as easily,
the mast track could be moved back farther.  This unwets the board better,
and viola, less friction and more speed.  Seems like this happened around
the early
to mid 90s.  The sails came first.

So, although there's probably a conflict between an old sail and a new board,
there shouldn't be any problem using a new sail on a really-old board?

The mast track will probably be too far forward with an old board, so
you will over-close the gap when using a modern sail with a low cut
foot (slalom/race sails).  Wave sails would possibly work.

I think you'll find that new sails do work pretty well on old boards, but
you'll want to
put the sail as far back in the slot as you can get it, and in the case of
really old boards,
the COE is still gonna be too far forward for optimal efficiency.  Realize
also that
the wide point of the boards also moved back to balance where the rig lives
in modern boards, so it's not perfect.

The opposite (old sails on new boards) doesn't work nearly as well.

At least, that's my opinion,
