CUNNINGHAM/DOWNHAUL
The Cunningham or downhaul consists of two (2) components: a line that is
attached to a grommet that is located inside the mainsail sleeve, and a block
and tackle system that is led to cleats on either side of the boat.
First attach the lower end of the block and tackle to a metal bracket located
at the base of the mast. The lower end consists of a double cheek block and
two single blocks. Attach all three with the double in the middle. The lines
that exit through the single blocks are led directly to the upper cleat located
on the wings. The line through the port sheeve goes to the port cleat and
the other goes to the starboard cleat. This allows you make adjustments to
cunningham tension while hiking out. It’s a good idea to tie “figure-8” knots
in each end of the cunningham line so that it can’t come undone.
Tie the single piece of line to the grommet on the sail and then attach it to
the becket on the top of the three blocks that forms the upper part of the
block and tackle system. You can add some tension to the sail to take the
wrinkles out of the luff. This is a good time to make sure that all the battens
are neatly in their cambers and have sufficient tension.
BOOM
The inboard end of the boom has a shaft into which you slide the gooseneck.
Before you attach the boom to the mast you need to pass the outboard end
through a loop that is attached to the clew of the mainsail. Slide the boom
through the loop and then attach the forward end to the gooseneck. You will
see a line on the outboard end of the boom going through a cleat located
on the top of the boom. This is your outhaul. Pass it through the small block
attached to the top of the boom and tie to the clew of the sail. Tension the
outhaul and cleat it off.
Note: At this point you are more vulnerable if the wind comes up, but
it’s only when you have attached the mainsheet that you may have a
problem.
