Sails and Rigging
12.5
bottom forward block and enters the aft boom. The line
travels forward to the sheave near the mast and contin-
ues around the sheave. It then exits the boom near the
gooseneck down to the mast base where it runs around
a block to the starboard organizer. It continues from the
organizer to under the sea hood and to the sheet stopper.
From the sheet stopper the line can then be used by the
winch for additional torque when trimming.
12.6.7 Jib Sheets
The jib sheets are a pair of lines that control the jib clew
and the shape of the sail. One of which is used at a
given time. Each line is attached to the jib clew with one
line running around the inner shroud to the port jib track
sheave car and the other to the starboard. Each line then
travels aft to a turning block in the aft cockpit and ends
at a helm winch which can be used for additional torque
when trimming.
.
12.6.8 Mainsheet Traveler Lines
The mainsheet traveler lines are a pair of lines that control
and facilitates the lateral movement of the boom. Both
line ends are located within the cockpit. Both lines origi-
nate from the arch top and are generally mirrored port
and starboard. The line arrangement exists to control
the movement of the traveler block car as it travels on its
track. Each line is attached to the traveler end block and
travels inboard to the traveler car’s aft control sheave. It
travels around the control sheave and back to and around
the end block to the traveler car’s forward control sheave.
It continues around the control sheave and outboard to
and around the over-the-top or under-the-top block down
to the cam cleat mounted to a plate or rail on the inboard
arch leg.
12.6.9 Vang Line
The vang line is used to apply downward force on
the boom and thus the shape of the sail. The vang is
attached to the base of the aft mast and to the bottom
of the boom, generally forming a 45 degree angle. The
standard vang is a block and tackle arrangement. The
optional rigid vang (standard with the in-mast furler) is
a piston arrangement controlled by the vang line. From
the vang, it exits the assembly from the top boom end
and travels to the mast base where it runs around a mast
base block to the port organizer. It continues from the
organizer to under the sea hood and to the sheet stopper.
From the sheet stopper the line can then be used by the
winch for additional torque when tightening.
12.6.10 Spinnaker Halyard
The spinnaker halyard raises the optional spinnaker or
reaching sail. The mast end is shackled to the head of
the spinnaker and travels up to the forward mast sheave
box located above the jib sheave box. It passes over the
sheave and down the mast internally to an exit point on
the port side. From there it continues to the mast base
where it runs around a block to the port organizer. It
continues from the organizer to under the sea hood and
to the sheet stopper. From the sheet stopper the line
can then be used by the winch for additional torque when
raising.
12.6.11 Reef Line 1
Reef line 1 lowers the mainsail to the first reef point. The
line exists for the standard conventional mainsail only.
The sail end of the line exits the top of the aft boom from
the end cap sheave and travels up and through the first
cringle near the clew. It travels down to the boom where
it is looped around the boom and knotted. The other end,
which emerges from within the forward boom, travels up
from the forward boom sheave to and through the lower
forward cringle near the tack and down through an eyelet
immediately above the gooseneck on the mast. It then
travels down to the mast base where it runs around a
block to the starboard organizer. It continues from the
organizer to under the sea hood and to the sheet stopper.
From the sheet stopper the line can then be used by the
winch for additional torque when reefing
12.6.11 Reef Line 2
Reef line 2 lowers the mainsail to the second reef point.
The line arrangement is the same as Reef Line 1 (above)
except for the reef points are at the second cringle and
the line is routed port side.
12.6.12 Spinnaker Sheets
The spinnaker sheets are a pair of lines that control the
spinnaker clew and the shape of the sail. One of which
is used at a given time. Each line is attached to the spin-
naker clew with one line running around the outer shroud
and lifelines aft to the spinnaker block located on the
aft cockpit toerail. The other sheet is routed around the
forestay, outer shroud and lifelines to the opposite spin-
naker block. Each line ends at a helm winch which can
be used for additional torque when trimming.
