the stem plate.
Attach the tack line to the spinnaker tack and route it
through the block and cleat it off on the forward port
cleat.
Attach the halyard to the head ring of the sail.
Attach a sheet to the clew ring of the spinnaker and
ensure the line is led aft outside the shroud and life-
lines to a stand-up block just aft of the arch legs.
Run it to the helm winch allowing total slack in the
sheet.
The sheet that is not being used, the lazy sheet,
should also be attached to the clew of the spinnaker
and led forward in front of the headstay, and then
back on the other side of the boat, outside the shroud
and lifelines, to another stand-up block positioned
just aft of the arch legs.
Take that sheet and lead it to a winch, leaving some
slack.
12.7.13 Retuning the Mast
The final step is to check your settings by sailing in 10-
15 knot winds (see the Getting Started chapter in this
manual for details on an initial excursion):
Sail upwind and check if the shrouds on the leeward
side are slack. If so, tighten them to remove approxi-
mately half the slack - keep track of the number of
turns.
Tack and repeat for the other side.
Continue until you are satisfied with the tension where
the leeward side does not get loose when the boat is
heeled.
Sight up the mast and verify it is still straight from side
to side and adjust the appropriate rigging to correct,
if necessary. (Keep in mind it is possible to over-
tighten.)
Tension the jib furler/forestay by adjusting the forestay
rigging screw (see jib furler manufacturer’s OEM
manual).
Ensure the mast is tuned to a 6” to 8” bend on the
standard mast and 2” to 3” bend on the furling mast
(discussed previous). Adjust the bend as required.

12.7.14 Rigging Review
Once the rig is tuned, you should make sure to add the
cotter pins to all the rigging, bending back the ends and
taping them to prevent snagged lines, sails, and fingers.
In general, tie figure eight knots in the end of sheets to
prevent them from running back through the stoppers or
cars.
12.8 Sail Reefing & Stowing
Reefing the sails reduces the area of the sails. This can
improve the boat’s stability and reduce the risk of damag-
ing the sails or boat hardware in strong winds. Reefing is
a subset of stowing the sails. In other words, stowing the
sails fully reduces the sail area of the sails.
12.8.1 When to Reef
When determining your sail configuration, wind strength
will be a key factor. Figure 12.9 provides apparent wind
speed (AWS) levels and the suggested sail configuration.
It is critical to maintain sail discipline at these levels for
the safety of those on board and the protection of your
vessel.

As a rule of thumb, consider reefing whenever the boat
heels to 22 degrees or more (an inclinometer will assist
in determining the degree of heel).
NOTE: Excessive sail area or modifications to the original sail
and/or rig design can cause unsafe conditions including knock-
down/broach.
NOTE: The wind strengths tabulated above include a margin
for the effects of gusts. If violent winds or confused or breaking
seas exist, additional caution should be exercised.
NOTE: Remember:
