 With
Doyle's ZENITH rollaway mainsail, you can
have the ease of in-mast roller furling without
giving up the performance of a conventional
mainsail.
The Doyle ZENITH mainsail incorporates three
revolutionary full length vertical battens that
maintain the 10% roach normally sacrificed with a
conventional Rollaway Mainsail. This added area is critical to performance by
putting crucial girth back in the top 1/3 of the
sail. Without ZENITH battens, the head of a normal
Rollaway Mainsail is narrow and inefficient.
When furling or reefing, the ZENITH battens are
parallel to the luff to allow easy furling.
Zenith Features:
-
The
Doyle ZENITH mainsail is constructed using
premium sailcloth and includes an integral clew
block for maximum sail area.
-
UV
protection is added to the clew to protect the
exposed portion of the sail when rolled up.
- Large radial corner patches are used for
better load distribution.
- Seams are taped as well as sewn for maximum
strength. Telltales and sail bag are included.
- The fabrics selected are premium quality for
maximum durability and to provide excellent
cruising performance season after season.

Trimming Tips |
Sailing
with your Doyle Zenith Full Batten Furling Mainsail
Your
Doyle Zenith Mainsail incorporates full-length
fiberglass rod battens. These battens run vertically
from foot to leech, parallel to the sail luff. The
battens are designed to allow added roach and to
open the leech for a proper trailing edge, and
improved performance. When reefing, these battens
also act as a luff tensioner, making for a smoother,
flatter reefed sail.
Tips:
1. First and foremost, the mast must be set up
correctly. The mast should be reasonably
straight. Too much mast bend, and/or too little
tension on the luff rod can cause problems in proper
sail furling operation. Please consult the mast
manufacturer set-up instructions.
There
is no such thing as a Self-furling sail!
Attention needs to be paid to the sail when
unfurling, reefing, or furling up.
2. When un-furling the sail, the furling line
should be held in check while pulling the outhaul
line out so that even tension can be kept on
leech and foot. This will prevent
“freewheeling” of the furling unit, avoiding
possible overrides of the furling line and/or the
sail, as it is deployed.
3. After the sail is deployed, tension the outhaul and
mainsheet for the desired course. Some leech line
adjustment may be required at this time, especially
the first time the sail is set. Pull gently to just
remove any leech flutter, do not over tension.
4. When furling, the outhaul line should be held in
check so that even tension can be kept on
leech and foot when furling. This will
provide a tighter more compact furled sail and help
to eliminate sail hang up due to a loose roll.
5. When reefing or furling, because the battens are
parallel to the luff, they provide a good indicator
as to how evenly the sail is furling up. Mainsheet,
topping lift and/or vang may need adjusting to allow
even furling. Preferably, on a calm day and at the
dock, spend some time rolling and un-rolling
your sail to get a better feeling of tension
required, as well as vang and topping lift settings.
6. Once you have a good feel for the operation, you may
wish to mark your vang and/or topping lift control
lines with a quick reference mark.
7. Reef location indicating stripes are located
on the foot as well as the leech of the sail near
the front two battens. Although the sail can be
reefed to any point, these are the recommended reef
points to allow the battens to provide a nice tight
luff and flat, smooth reefed sail.
With a little attention and practice, your Doyle ZENITH
Main will provide you with un-paralleled
performance and service. Happy Sailing!
