Adjustments Halyard Tension/Backstay Tension
■ HALYARD TENSION
The jib halyard should be firm, but not too tight.
TIP: The luff foil system supports the sail along its entire
length so halyard tension is required only to shape sails,
not to support them. Use only enough halyard tension to
remove some wrinkles along the luff. Do not tension the
halyard enough to cause vertical wrinkles in the luff. Use
halyard tension to adjust draft position of the sail to suit
sailing conditions. Your halyard should be firm but not
tight. If in doubt, release halyard tension. To protect the
sail, ease the halyard when the boat is not in use.
■ BACKSTAY TENSION
Good stay tension helps furlers turn more easily. Make sure
to ease jib halyard before tightening backstay to prevent
damage to furler.
CAUTION!: Tensioning backstay without easing
halyard will cause halyard to tighten excessively
causting damage to halyard swivel and tack swivel.
