fully adjusting some tension on the sheet to keep the sail
taught.
2. Install the out haul line in the boom with the messenger
line provided and lead from the sheave at the back of the
boom through the lower cringle at the back of the sail and
aft to the end of the casting.
3. Install reefing lines in the boom with the messenger
line provided and lead from the sheave through the rel-
evant cringle at the back of the sail and then down to the
sliding eye on the bottom of the boom. Pull enough slack
into the reef line so that the sail can be fully raised unim-
peded by the reef lines. Tie the mainsail onto the boom
with the sail ties provided.
4. Install the jib sheet onto the jib and lead the sheets
between the shrouds and aft to the traveling cart of jib
track on side of the deck, then lead the jib sheet to stand-
up turning block on toe-rail then tie it on furling winch for
further operation. Tie figure eight knots in the end of the
sheets to prevent them from running back through the
turning block.
5. Raise and unfurl sails, beginning with the main and
then the jib while powering into the wind. Once each
halyard, is tensioned by the winch, the halyard can be
pushed down into its respective rope clutches and the
halyard removed from the winch, freeing the winch for the
next halyard or sheet. However, care should be taken not
to inadvertently open the rope clutches, since the sails
will lower rapidly if this is done. When the sails are raised,
the boat can be laid off and the engine turned off.
6. Once the main is sheeted in and you are sailing
upwind, confirm the main topping lift position. The main
should be capable of sheeting in hard without the topping
lift being tight. With the main sheeted in hard, the topping
lift should have eight to ten inches of sag and should be
adjusted accordingly.
7. After a day of sailing, the sails should be lowered /
furled in while again powering into the wind, with the jib
furled in first and then by lowering the main. Protect your
sails by covering them with the lazyjack sailcover or furl-
ing them completely up.
13.3.2 Tuning the B&R Rig
The easiest method for tuning the B&R rig is to perform
step one as follows before the mast is stepped, with it
lying aft side down on two sawhorses. Begin with all rig-
ging slack. If the mast is already stepped, loosen all the
rigging, and then proceed to step one.
1. Start with all the rigging slack. Then induce the mast
bend by tightening the reverse diagonals (diamonds).
Measure the band by tensioning the topping lift line or
the main halyard between the masthead and the goose-
neck. Mast pre-bend, the maximum amount of
depth of
curvature (D) occured on middle height of the standard
rig (non-furling mast) should be around 0.5% of the length
of “P” and do not exceed 2% of “P”. Mast pre-bend, the
maximum amount of depth of curvature (D) occured on
middle height of the furling rig (furling mast ) should be
around 0.5% of the length of “P” and do not exceed 1.0%
of “P”.
The alternative measurement can be done for
determining the mast pre-bend. Measuring perpendicular
from the aft face of the mast to the halyard at the deepest
part of the bend. It can be less than that based on the sail
shape and your own preference. The bend should also be
evenly distributed along the mast to give a smooth shape.
Keep in mind that bending a furling mast may make it
more difficult to furl and will not do much to flatten the
sail as in a standard rig. It is very important that the mast
also be straight from side to side at this time. Tighten or
loosen the diagonals to achieve this.
2. Step the mast with all shrouds attached but with the
turnbuckles completely loosened (if the mast was not
already stepped).
3. Attach the jib halyard to a cleat on the bow to support
the mast in a raked position (the masthead should be
about 2’-0” {60cm} behind the step). Attach the verticals
and tighten them until you can just see the hole for the
cotter pin in the turnbuckle. Tighten the jib halyard until
you can attach the forestay. At this point, the masthead
should be raked so that a weight hung on the main hal-
yard hangs about 18” behind the mast step.
4. Use the main halyard to check that the mast is cen-
tered from side to side. Pull it tight and mark the halyard
next to the verticals chainplate. Now do the same in
the other side to see if the marks line up. If not, tighten
and/or loosen the verticals until the marks line up. Once
the masthead is centered, begin tightening the verticals.
While tightening the verticals, you may notice the bend
in the mast increasing. Now you can tighten the lowers
then tighten D2, which will tend to straighten the lower
part of the mast. Be sure to tighten port and starboard
sides evenly.
5. Now you should tighten the headstay until it is
approximately half closed as well. This should induce the
approximate amount of headstay tension so the headstay
