2.4. Main
Unroll the main on a at surface you rst swept and make sure it doesn’t have sharp objets that
could damage the sail. Unpack the battens and place them on the main in the right order.
Slide the battens all the way into the pockets and put them under tension. Note that different
sails use different systems to tension the battens. You’ll know you put to much tension if you have
problems to ip the sail’s camber over while sailing. If you tensioned them to lightly you’ll see
wrinkles forming around them.
