The battens are tensioned
using the hex-key tool found under the strap in the
tack handle. Insert the hex-key into the cap screw
inside the SBT at the leech end of each batten. Turn
the hex-key to the right (clockwise) to tighten.
Tension the battens JUST until the wrinkles across the
batten pockets disappear. Look for a continuous
smooth shape to the sailcloth next to the batten pocket (see photos
to the left). You should see a smooth reflection, with no wrinkles
alongside the battens. The batten tension will need to be re-
tightened after one or two uses as the sail sets into its final shape,
but then it need not be readjusted for every session! If you leave the
batten tension too loose, the cap screws may fall out.
CAUTION: DO NOT OVER-TENSION THE BATTENS - POOR
ROTATION, EXCESSIVE FOIL DEPTH AND DAMAGE TO THE SAIL CAN RESULT.
7. ADJUST THE T-TOP HEAD BATTEN
The head batten on the X-T
2
does NOT require strong batten tension.
This batten is designed to function under deflective load to pull
upwards on the leech. Over-tensioning the head batten will cause
the head area to lose all support. If the head and tip of the sail look
dramatically loose, reduce the head batten tension to increase
support to the head area (See photos to the left).

Release any outhaul tension and allow the sail to relax naturally to its
fullest depth. Pull just enough outhaul tension to pull the sail up off the
boom tube and tighten the clew area. This is a good all-around outhaul
setting. If necessary, re-adjust the back end of your boom to just touch
the clew of the sail and tie off the outhaul. If you are using the
adjustable outhaul system you need to set your boom length slightly longer to allow for the
outhaul to be pulled further.
From a neutral setting, slightly less outhaul (negative) will make the sail fuller and more
powerful for reaching, but it will also be harder to control when over-powered or sailing
upwind. For upwind sailing or over-powered conditions, a small amount of outhaul tension
(positive 1-2 cm, or 2") will improve performance by making the sail flatter and tighter.

You can expand the X-T
2
’s wind range significantly by simply adjusting your downhaul. As a
general rule, you release a little downhaul tension when sailing in lighter winds. This creates
more power by allowing the sail to be fuller, and by increasing leech tension. It will also reduce
the twist, which makes pumping more efficient.
In stronger winds or very bumpy water, the downhaul should be pulled more to tighten and flatten
the sail and reduce the excess power. Strong downhaul tension also increases the twist, which
improves control and handling by lowering the center of effort. IMPORTANT: Whenever you pull or
release the downhaul, you’ll need to readjust outhaul too, as the two adjustments are inter-related.
The tack strap at the base of the sail can be used to slightly alter the depth and tension in the sail.
For very bumpy water conditions, or when you are sailing very over powered, pull the tack strap
very tight. This will increase the depth of draft below the boom and increase tension along the foot
edge, which lowers the center of effort and allows the upper leech to respond more freely.
To save time rigging next session, take note or mark off the position of successful
downhaul and outhaul settings so they are easy to repeat. See the Sailworks website –
