3.3.2 Tunin
g
the B&R Ri
g
The easiest method for tunin
g
the B&R ri
g
is to perform
step one as
f
ollows be
f
ore the mast is stepped, with it
l
y
in
g
a
f
t side down on two sawhorses. Be
g
in with all ri
g
-
g
in
g
slack. If the mast is alread
y
stepped, loosen all the
ri
gg
in
g
, and then proceed to step one
.

depth of

should b

around 0.5% of the length
of “P” and do not exceed 2% of “P”.

f
the mast to the hal
y
ard at the deepest
p
art of the bend. It can be less than that based on the sail
shape and
y
our own pre
f
erence. The bend should also be
e
venl

distributed alon

ive a smooth shape.

sail as in a standard ri
g
. It is ver
y
important that the mast
also be strai
g
ht from side to side at this time. Ti
g
hten or
loosen the dia
g
onals to achieve this.
2. Ste
p
the mast with all shrouds attached but with the
turnbuckles completel
y
loosened
(
i
f
the mast was not
alread
y
stepped
)
.
3
. Attach the
j
ib hal
y
ard 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 ti
g
hten them until
y
ou can
j
ust see the hole
f
or the
c
otter pin in the turnbuckle. Ti
g
hten the
j
ib hal
y
ard until
y
ou can attach the foresta
y
. At this point, the masthead
should be raked so that a wei
g
ht hun
g
on the main hal-
y
ard han
g
s about 18” behind the mast step.
4. Use the main hal
y
ard to check that the mast is cen-
tered
f
rom side to side. Pull it ti
g
ht and mark the hal
y
ard
next to t

While ti

notice the bend

y
ou can ti

hten the lowers

the mast. Be sure to ti

y
ou should ti
