GETTING READY TO SAIL
main should be capable of sheeting in hard with-
out 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 ac-
cordingly. When at dock or at mooring, the top-
ping lift can be readjusted to raise the boom to a
comfortable height above the cockpit.
21. Final conformation of the mast tune as well as
finer tuning, if you desire it, will take place when
sailing by sighting up the spar while going upwind
in about ten to twelve knots of breeze. The mast
should maintain its 2” (5cm) fore and aft bend, but
should also still appear straight transversely with
the leeward main shroud still retaining its tension
and not going noticeable slack.
If the leeward rigging does go slack when sailing,
apply more tension uniformly to both shrouds by
first tightening the leeward rigging three half turns
and then after tacking, tension the new leeward
rigging the same amount. Continue this proce-
dure, as necessary until the leeward upper shrouds no longer appear slack and forestay sag
has been reduced. Removal and reinstallation of
the turnbuckle cotter pins will be necessary to make
these fine tuning adjustments.
22. Once the upper shrouds are tensioned, again
sight up the spar to make sure that the middle of the
spar at the spreaders is not falling to leeward or
bending to weather. Adjust and uniformly retension
the lower shrouds as necessary.
NOTE: Standing rigging will stretch slightly when
initially loaded. Therefore, the rigging may have to
be further tensioned slightly after a few sails in a
strong breeze to compensate for this initial stretch.
Once the mast is tuned and initial stretch is taken
out, the rig should need retuning only at the begin-
ning of each season.
23. After a day of sailing, the sails should be low-
ered while again powering into the wind, with the jib
lowered first and then the main.
