| This page describes a Lazyjack
installation for C34 owners.
Lazyjacks -- Home made for about $25 and no holes in
the mast or boom.
I used 1/4 inch braided nylon line which goes from
the aft portion of the boom over the top of the
starboard spreader around the front of the mast and over
the top of the port spreader back to the aft portion of
the boom. I was afraid that smaller diameter line would
get caught in the crack between the spreader and mast.
In that area I doubled the line and added leather chafe
guard in the area where it crosses the aft portion of
the spreader. I used a monkey fist to throw the line
over the starboard spreader, then went to the bow and
threw it back over the port spreader.
I used some plastic clips that are clipped on to the
cable portion of the boom's outhaul to secure that line
(when the lazy jacks were completely finished). This
line is not tight but hangs in a loose curve. I split
the boom into quarters by sewing three vertical strands
of line onto each side of the line I threw over the
spreaders. These lines are not the same length. The
longest is toward the mast and the shortest is aft. I
covered the sewing joint with liquid rope whip and let
the line hang down to about a foot above the boom.
I then sewed a loop on each side of these three pairs
of lines using heat shrink as chafe guard. I secured a
length of shock cord through the line loop on one side
by sewing it together. On the other end of the shock
cord I sewed a bronze swivel eye snap (these sewing
joints are also chafe guarded with heat shrink). The
swivel eye snap connects to the line loop on the
opposite side of the boom. As a result, the shock cord
hangs loosely under the boom. This was done with the
mainsail and the mainsail cover on to get the correct
I've had these on for at least 9 years and there have
been no chafe problems with either the mainsail or the
mainsail cover. They can be easily unsnapped and wrapped
around the mast when I put up our large sun cover (mast
to back stay), full boat winter cover, or as Gary
Wiseman has pointed out, wrapped around the mast to
counter mast pumping. Several other people in Fleet 12
have copied this idea.
