6. Remove the battens from the batten bag, and check each batten for symmetry against the corre-
sponding batten from the other wing. Align the battens at the nose, and at about the 60% chord
point as shown. There should not be any deviation of more than 1/8" from one to the other along
the full length of the battens. Note: If you fly in a dusty or sandy environment, it will help to
prolong the life of your batten pockets in your sail if you wipe each batten with a rag before you
insert it in the batten pocket.
7. Wills Wing convention is that black tipped battens go in the right wing and white tipped battens in
the left. Top surface cambered battens are numbered from the tip inwards, and the shortest
cambered batten in a Sport 2 is designated as the "#2" batten (there is no "#1 batten"). Working
from the root out, install the three longest cambered top surface battens in each wing of the sail.
Do not engage the rear tips in the trailing edge at this time.
Insert the battens carefully, so as to minimize stress and wear on the sail. Do not
hold the battens by the rear tips, and do not apply significant force to the rear tips
during insertion or removal - the lever type tips can be broken if the force required
for insertion of removal is applied to the tip. Do not insert or remove the longest top
surface battens with the crossbar tensioned and never insert or remove battens with
heavy wind pressure on the top of the sail or in any condition which causes the
battens to slide with great resistance in the pockets. Take care when inserting the
longer cambered battens that the front batten tip does not catch the aft edge of the
Mylar insert through the sail and fold it under. This is best avoided by keeping the
trailing edge of the sail as low as possible, and lifting on the batten in the area
behind the Mylar pocket if necessary as you push the batten in. If the Mylar insert
does become folded under when inserting a batten, remove the batten, smooth the
Mylar down, and reinstall the batten. Also take care not to force the rear batten tips
