Sails and Rigging
12.4
12.6.1 Main Halyard
The main halyard raises the mainsail. For the conven-
tional mast, the mast end of the halyard is shackled exter-
nally to the head of the sail. The line then rises to the
masthead and over a sheave (pulley). It then travels back
down the mast internally to an exit point on the starboard
side. From there it continues to the mast base where it
runs around a block (pulley) to the starboard organizer.
It continues from the organizer to under the sea hood
and to the sheet stopper (jammer). From the sheet stop-
per the line can then be used by the winch for additional
torque when raising.
For the furling mast, the main halyard path is similar,
however, the mast end is attached internally to a swivel.
This swivel travels up and down the furling foil (which
holds the mainsail luff and revolves when furling or unfurl-
ing). From the swivel, the halyard runs up to the mast
head and over the masthead sheave. It then continues
the same course to the cockpit as the conventional main
halyard.
12.6.2 Jib Halyard
The jib halyard raises the roller furling jib. The mast end
is attached externally to a swivel. This swivel travels up
and down the jib furling foil (which revolves when furling
or unfurling) and is integrated within the forestay. The hal-
yard rises up to a sheave box, first box below the forestay
attachment, and over the sheave. It then travels back
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.
12.6.3 Topping Lift
The topping lift supports or raises the boom. The mast
end of the topping lift is shackled to the aft end of the
boom. It then rises to the masthead and over a sheave.
It travels back down the mast internally to an exit point
and lashed to a cleat on the mast.
12.6.4 Main Furling Line
The main furling line furls the mainsail (see the next sec-
tion on Boom Outhaul, which unfurls the mainsail) within
the optional in-mast roller furler and does not exist with
the standard conventional mainsail. The mast end of the
main furling line is attached to the furler screw within the
mast. It exits the aft mast beneath the boom through the
screw slot and travels aft to a block on the boom located
forward of the vang (see Vang Line section below). From
there it continues to the mast base where it runs around
a mast 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 furling.
12.6.5 Mainsail Outhaul
The outhaul pulls the mainsail aft along the boom and
controls the shape of the curve of the foot of the sail. If
the rig is for a conventional mainsail, the mast end of the
boom outhaul is attached to the mainsail clew and travels
toward the aft boom cap.
If the rig is for a in-mast furling mainsail, the mast end
of the boom outhaul line is shackled to the forward shaft
of the boom traveling car. It travels up and around the
mainsails clew sheave and down and around the boom
traveler car’s aft block toward the aft boom cap.
The line enters the boom by traveling down and around
a boom end cap sheave and forward toward a sheave
near the mast. It travels around the sheave and exits
the boom near the gooseneck. It continues down to the
mast base where it runs around a mast base 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 pulling.
12.6.6 Mainsheet
The mainsheet controls the lateral movement of the boom
and thereby the mainsail clew. The amount of tension
on the mainsheet determines the extent of the boom’s
lateral movement or travel. This travel is facilitated and
controlled by the mainsheet traveler assembly located on
the top of the arch (see Traveler section). The mainsheet
is a double open ended line which starts and ends in the
cockpit. The “end” of the line runs through a sheet stop-
per positioned on the port arch rail’s inboard side down to
and around the block on the cockpit coaming and leads
to the port helm winch. From the sheet stopper it travels
up and around the arch’s port over-the-top block and
travels inboard to the arch’s center stand-up block. The
line continues around the center stand-up block to and
around the aft boom’s bottom aft block and back toward
the traveler. It then is routed around the traveler car block
and back to the boom. It continues around the aft boom’s
