Our lever is a HA 4192. It is double-sided and has a U-shape when viewed from above. We
shackle a triple block to the top corner of the lever. Where the shackle pin passes through the
"U" we insert one loop of a 6mm (¼")-shockcord (about 35 cm (12") long with [seized] loops at
each end). The other loop goes over the wingnut on the gooseneck to keep the lever from
flopping sideways too much. The triple block meanwhile, requires four additional blocks: one on
each side of the mast step and one on each side of the centreboard box.
The diagram to the right shows
the starboard side arrangement
(plus block 2S which will be used
for the outhaul control line). The
port side is a mirror image of this
arrangement.
The diagram above shows the set-up as both vang and outhaul controls reach their cleats on the
aft edge of both sides of the thwart. The double blocks should have their eye straps slightly aft
of the thwart along the upper part of the CB box such that the control line under tension will
leave the block about 3 mm (1/8") aft of the thwart. This results in a smooth entry into the clam
cleat (CL 211) (or the Lance cleat which I now prefer). The CL 211's are mounted on the aft face
of the thwart (or a six inch piece of 2 x 4 placed under aft edge of a wood thwart). The cleats
should angle slightly up from horizontal to conform to the angle of the rope coming up from the
double block to the cleat.
Threading the vang control line: We use 5 mm. soft-braid about 6 meter. (20'). Take one end of
the line and feed it out through the upper clam cleat on the starboard side. Tie a figure eight
knot and leave six inches of loose end for better grip in emergency. Take the unknotted end and
feed it through the upper sheave of the double block and forward under the thwart along the CB
box. Up through cheek block 1S and through the starboard sheave of the triple block on the
lever. Down through 3S and back up through middle sheave of the triple block, down to the port
counterpart of 3S, up through the port sheave of the triple block, down to the port counterpart
of 1S, back along the CB box, under thwart, into the upper sheave of the port double block and
out through the upper clam cleat. Finish with Figure Eight knot and leave six inches of loose end.
Vang needs:
• one lever HA 4192 plus prepared wires at each end
• one triple block with shackle and looped shock cord
• two double blocks, cheek blocks, bullet blocks, CL 211 clam cleats (or RWO Lance cleats)
• four eye straps
• all screws
