Upper shrouds should also be tightened equally and have about an inch of “give”
to them. Forward lower shrouds should have one to two inches of “give”, and the
aft lowers slightly more.
Under no circumstances take up the rigging to bar tight tension. Both the mast
and the boat can be severely damaged by excessive tension.
Fine tuning of the rig can be completed after the boat has been sailed, and may
have to be done again after the boat has been out in strong winds. When sailing,
it is important that the mast remain straight and as nearly in column as possible at
all times. While sailing close hauled, sight up the mast track and note any mast
curve. Does the mast appear to be falling off to leeward at the top, or does it look
to windward? Repeat this procedure on the opposite tack.
If the masthead is falling off on both tacks, the forward lower shrouds are too
tight and the upper shrouds are too loose. If the masthead hooks to windward, the
upper shroud is too tight in relation to the lower on the same side. When sailing
to windward, the forward lower shrouds bear a greater load than the after lower
shrouds; however, the after lower shrouds on the windward side should never be
loose. All shroud tuning should be done from the leeward side. If the rig seems
to be equally balanced when you begin, duplicate every half turn from side to
side.
Be sure that every locknut is tightened after adjusting turnbuckles. Check to see
that all cotter pins or rings are in place and that all sharp edges are taped.

Sheets
Swapping sheets end for end will extend the useful life of a sheet that has started
to chafe where it passes a sheave or engages a cam cleat.
