WARNING:
It is extremely important that the
turnbuckles are adjusted equally.
Overtightening one side can cause a
bend in the mast. The diamond wire
adjustment not only affects mast bend
and sail shape, it is an important support
component of the mast extrusion. If the
diamond wires are loose or broken, the
mast can be permanently distorted or
could fail completely. The diamond wires
cannot be tightened sufficiently by hand.
Use a wrench to make the last two or
three revolutions of the turnbuckles.
Wires stretch with use and require
periodic inspection and retightening.
13.8 Locate the shroud wires and the upper
forestay wire. Place the three wires on the
large bell shackle. The upper forestay wire
should be positioned between shroud wires.
(FIGURE 21)
13.9 Put the pin of the large shackle through
the bottom hole on the mast tang. After
tightening, secure the shackle pin to the
shackle with safety wire to prevent the pin from
backing out. (FIGURE 21)
13.10 Place the small bell shackle in the
middle hole of the mast tang. Slide one of the
trapeze wires onto the left side of the shackle
and one on the right side of the shackle.
(FIGURE 22)
13.11 Secure the shackle by attaching the pin
through the top hole of the mast tang. Be sure
to tighten with a pair of pliers. (FIGURE 22)
