 Image 22 : Outhaul the sail. Pull to within 1 cm of the rear end and fine tune for the conditions.
Image 23 : Check the required boom length printed on the foot of the sail.

Image 24, 25 : It is helpful to actually measure the boom length for optimum performance.
On Fiberspar booms, check the marked body lenght, then add extra distance in extension. For instance, if your sail asks for a 220cm boom length, and you have a 200cm boom, extend the rear so you see the number 20 marking.

If this is the first time you are rigging your sail, you must tension the battens so as to remove the wrinkles. Your sail should have a smooth aerodynamic shape when properly tuned.
On pre-2002 GTX models, around batten #7 and close to the luff, there are slight wrinkles that are diagonal to the sail, radiating from the foot to the clew. Some of them will not disappear with proper batten tension as this extra shape is not supported by a camber inducer. As the sail Flexes under load, this wrinkle disappears.
Image 26 : After the sail is rigged, connect the rig to the board, looping the tack strap around the top of the mast foot.

Use only light tension, as this simply holds this area in line with the rest of the foot.
Note: After you use your new sail for the first time, you will need to re-tension the battens again, as the sail stretches and settles to its desired shape.
