MAST TUNING

Improper tuning or handling of spars and rigging can cause mast or
rigging failures. The following are few suggestions for tuning your
mast and rigging:
1. Mast should be set straight athwartships with a slight rake aft
of about 3 (three) Inches.
2. Shrouds must be kept at a reasonable tension to avoid
unnecessary compression on the mast causing it to bend.
3. Forestay/backstay 'just firm' with backstay slightly tighter.
4. While sailing to windward in a series of tack, make necessary
adjustments of the turnbuckles on the slack leeward shrouds after
observing the mast on the opposite tack.
5. Check mast by sighting from the deck up will reveal whether
further adjustments are necessary.
6. For better windward performance, the jib stay and backstay may
be tightened up more. Remember to slack off the amount you "took—up"
after the sail to avoid unnecessary strains on the rigging.
7. UNDER NO CIRCUMSTANCES SHOULD ANY OF THE RIGGING BE SET UP
"BAR-TIGHT".
