13:00 SABRE 30 SPARS AND RIGGING ­ TUNING AND ADJUSTMENT
The following procedure should be followed to adjust the standing rigging on a Sabre 30
after the mast has been put in place with medium tension on all stays.
13:01 THE VERTICAL SIDE­TO­SIDE POSITION of the mast is measured by using the main
halyard to determine that the distance from the masthead to both toerails is equal. It
may be necessary to add a short piece of rope to the shackle end of the halyard to reach
first one toerail and then the other. Adjust the upper shroud turnbuckles to correct any
lean of the mast relative to the hull.
13:02 THE UPPER SHROUD turnbuckles should be adjusted to obtain a reasonable degree of
tension in the shrouds. While sailing at a 25 degree angle of heel the correct upper
shroud tension will allow the leeward shroud to be reasonably slack without appreciable
tension, but not so loose that is moves in the breeze. Excessively tightened shrouds will
distort the shape of the hull and could cause structural damage.
13:03 THE FORESTAY AND BACKSTAY should next be adjusted to be reasonably tight, but
without overloading the hull which could cause structural damage. While sailing at a 25
degree angle of heel, the correct tension will allow the forestay to sag about 6" to 8"
aft at mid height. All sails are cut to allow for approximately this amount of sag in
the forestay. Equal adjustment of the forestay and backstay turnbuckles should result in
between 6" to 12" of rake aft at the masthead, which is normal. The mast rake can be
determined by using the main halyard. Tie a weight to the shackle and measure the
distance from the weight to the aft edge of the mast. This will give you the rake,
expressed in inches.
13:04 THE LOWER SHROUDS should next be adjusted to obtain a straight mast, side to
side, at a 25 degree angle of heel. This will result in the lower shrouds being about
half as tight as the uppers before you start to sail. If the lowers are too tight, the
mast will curve to weather at mid height. If they are too loose, the mast will sag to
leeward at mid height.
13:05 THE FORWARD LOWER SHROUDS should next be adjusted to give approximately 2" to 3"
of curve or pre­bend forward at mid height of the mast, while maintaining straight side­
to­side position of the mast per (4) above. To achieve this effect, it will be necessary
to loosen the aft lower shrouds slightly as the forward lower shrouds are being tightened
and vice versa. When the mast is properly tuned, the aft lower shrouds will be a little
looser than the forward lower shrouds and considerably looser than the upper shrouds.

13:06 CHECK: Be sure that all turnbuckles, toggles and clevis pins are secured with
cotter pins that are properly bent back and taped.
13:07 CAUTION: The majority of mast failures are caused by improperly adjusted rigging
that allows the mast to bend more than 3" sideways, or 6" fore­an­aft at mid height,
putting the mast out of column. Failure can also be caused by improperly placed or
missing cotter pins.
13:08 JIFFY REEFING: All Sabre yachts are equipped with two sets of jiffy reefing gear
as standard equipment.
To reef, ease off the main halyard and hook the reef tack grommet to the hook on one side
of the gooseneck. Restore proper main halyard tension. Pull in the reef line until
proper tension is achieved on the reef clew. Neatly furl the foot of the sail and tie it
off along the boom.
To shake out the reef, reverse the above procedure. (Refer to I­23)
13:09 CAUTION: All halyards run through the mast must be run with regard to through­
bolts at the masthead, tangs, spreaders, etc. The replacing of any through­bolts in the
