Just had a little thought; I wonder if there is a reason why batterns are at the angles they are. i've seen many images of promo class 5's with batterns (fully sheeted in) angled downwards towards the rear, others with horizontal and some angled up slightly.

Is there a reasoning behind the different angles, or is it due to styling? i notice open class 5's and class 3's nearly always have them horizontal.

Lachy,
I would bet you London to a Brick on, that the reasons are that we generally rebuild Old Sails for our purposes and lower cost than purpose built. I asked my Sail Maker roughly "Emachisit" his reply was $800 to a Grand. Go figure!! So whatever the angle was to start with will only be altered slightly when remolded.
I have 3 sails and one spare all have different Batten Angles.

What he said!
Mostly you want a sail that when fully sheeted in the battens are parallel to ground. This can change if a sail designed for one yacht is used on a yacht with a different mast angle or cant be sheeted in as much, or a stifer or more flexible mast.

I would say slightly up when not sheeted,the sightly down when going full stink, as you pass the horizontal position you start to increase your chord and flatten the foilshape, thoeretically giving you a faster sail, but if the sail is a recut I wouldnt stress to much over it.
its batten by the way not battern, those are what pirates use,cos they have a bit of rrrrrrrr in them
