MAST TUNING
Most of the following will require just a
few moments of your time, but it is
EX-
TREMEL Y IMPORTANT.
The results will
be a more pleasant sail and prolonged
future enjoyment of your
WINDROSE.
While the rig of your
WINDROSE
is quite
simple, special attention should be given
to the initial tuning of the mast, along with
the following suggestions,
especially
after your
WINDROSE
has been in a few
hard weather sails.
The mast should usually be absolutely
verticle or "plumb," both fore and aft, and
athwartships. On some boats the mast
should have a rake aft. The
WINDROSE
20 sails best with an aft rake. For normal
conditions, we recommend a "firm" rig
and
UNDER
NO CIRCUMSTANCES
SHOULD
ANY RIGGING
BE SET UP
"BAR- TIGHT'
OR LEFT SLACK.
Once
the mast has been stepped and the slack
taken
out
of
the
jibstay
with
its
turnbuckle, tighten the upper and lower
shrouds to about the same tension. Now
face the mast, reach out and pull inward
on the shroud and see the mast move in
that direction. Try to get tension on both
shrouds equal with about 2" of play on
both the uppers and the lowers.
The final tuning of the mast should be
done while sailing to windward in a 5 to
10 mph breeze. Since the part of the
mast above the jibstay and upper shroud
intersection (hounds), is unsupported, it
will properly "fall off" slightly to leeward.
This tuning should give the mast a
smooth even curve from head to deck. It
will be necessary to sight along the back
of the mast on each tack, from deck level,
to see this curve and make the proper
turnbuckle adjustments.
ALWA YS MAKE
ANY
TURNBUCKLE
ADJUSTMENTS
ON THE LEE SIDE WHEN THE SHROUD
IS NOT UNDER STRAIN.
Lower shrouds
act to keep the mast section in "col-
umn,"and they also prevent excessive
forward bending between the hounds
and the mast step.
