The Day Sailer - Edition #75 - Winter, 1980 - by Dick Brady
We experimented for ten years on DS #3158 with various rigging
systems and in 1979 got a DS by Rebel. It was a trembling
but courageous
hand that drilled the first hole in a beautiful deck. We planned
for minimum
holes with maximum controls.
Five double ended control lines lead to clam cleats on both
port and
starboard for ease of adjustment of the barber outhaul, cummingham,
vang,
outhaul, and jub luff. (Photo #1)
1. The barber outhaul leads from a thimble around the
jib sheet to a
thrudeck block (Photo #2) and turning
block to the clam cleat on
the opposite side of the boat.
2. The cunningham wire leads below deck through the
fairlead on
port deck close to the mast. (Photo
#4). The wire terminates at a
small Harken block. The control
lines achieve a 4 to 1 advantage
as shown in Plan A.
3. The boom vang goes below the deck after passing around
a sheave
fastened to the mast near the deck.
It has an 8:1 advantage by the
use of a double sheave. (See
Plan B.)
4. The outhaul is a duplicate of that on the cummingham,
except for a
lead through the deck on the starboard
side. The boom has a wire
sheave at both the outhaul and gooseneck
ends, with outhaul wire
ending in a loop 6" below the gooseneck.
This is connected with a
shackle to the top loop end of the
thru-deck wire.
5. The jib luff is a straight double ended line led
to cleats. No
mechanical advantage is needed.
To avoid load strain on the deck or keelson, the block systems
are
within an aluminum and stainless box frame. It rests on the
keelson with
wood blocks preventing side movement and the mast step limiting
fore-aft
movement. The 1/8" plate near the lower end has 3 blocks as
shown in Plan
A and B. The photos show only the pop rivets securing them.
The top cross
member of the "box frame" is bolted to the deck (The bolts are visible
in
Photo #2.
A Proctor Beta-Minus mast and Round Boom are used.
The mast step is mounted on an inverted aluminum channel which
fits
the keelson. A hinge joins this to another aluminum channel
which runs up
to the center board trunk. The main halyard wire loop fastens
to one of a
series of hooks. The jib halyard fastens to an adjustable
lever. John Barnett
of Rebel suggested a Harken Magic Box as offering better and easier
adjustment.
We are quite satisfied with this system of rigging as it mostly
evolved
on our old DS #3158. We look forward to years of enjoyable
sailing with
DS #11007.
