Fin/Mast Placement

Fin/Mast Placement

Post by Richard A. Peters » Fri, 10 Sep 1993 01:09:59


Can someone give me some general guidelines on the placement of
the fin and mast in relation to wind and size of board, sail,
and sailor.  Right now, I position the fin and mast in the
middle, simply out of ignorance.  I'd like to be able to make
more educated adjustments when setting up the board to get the
best possible performance.  I'm 145 lbs, and have an Obrien
Excellerator and ProAm.  My max sailing ability is about 20
knots of wind (low level intermediate?).  I've also had some
people advise me to upgrade to a larger fin.  The one that came
with the boards is pretty small.  Thanks in advance for any
advice you can provide.

Mast placement depends on type of board, type of sail, and conditions.
Generally boards are easier to ride and jibe easier and go upwind better
with the mast centered
or forward of center of the mast track, they're also much slower set up
like this.  With this type adjustment you almost have to experiment.

General rule for fins, put the fin tab in line with the back***of the
back strap.  Once again, this is just a starting point.

Finally, if this is one of those purple see through lexan fins, you should
buy a new fin.  Nothing I've said so far makes as much difference as a
good fin and the one which comes with both of your models is pretty
marginal.  If you are in marginal conditions (12-15MPH) get a big pointer,
if you get better conditions you could run a blade on the Pro Am.

For the mast position, try this :

        Place the board on its tail. Where your nose meets the mast
        track is where your mast should be. This must be qualified with repect
        to wind strength etc. But for around 20knots, not a bad starting
piont.

For fins, looser feel bring it forward. Faster runs bring it back. Again
play around a bit.

See how you go because your stance and style will affect these.
