Singlehanding or being with my wife (same as singlehanded) I
often wish I had lazy jacks. Have not seen any info regarding how
to set them up in my books on sails. How high, what size line,
where and how to fasten on boom, how fastened at the mast, are
they running rigging, etc.
Remember, I've an older wood Alden cutter with low aspect ratio.
probably 36 on the luff and 17.5 on the foot.

| 1066.1 | no help .....but a plan | ISLNDS::BAHLIN | Wed Dec 14 1988 15:57 | 19 | |
I too have been searching fruitlessly for anything on this. Having
failed in finding hints I assumed that maybe each installation should
be or has to be tweaked individually. In thinking about how to
tune an installation you will come up (I think) with a few
constants....
First problem is where to attach the uppermost part. My feeling
is that this is probably the least critical of all the parameters
so I am guessing 2/3 up the luff as a start. I plan to install
small cheek blocks there. The jacks will be installed as running
rigging as this allows adjustment of the tension. Also I plan to
make the base of the system in such a way that it can all be pulled
forward when sailing so that there is no sail chafe.
These are my 'constants' and they provide me with enough adjustability
to play with the other variables under a variety of conditions while
underway next season. That's my plan for now. If someone would
just give me all the parts now I could ............

Harken makes lazy jacks in two different sizes. One for "big" boats,
one for smaller boats. I don't know what the sizes really mean.
In the catalog in which I saw them, last year,
the price for either set was ,
less than $80.00.
The location of the upper mounting point may be more critical than
would be apparent. At least with full length battens, if the upper
mount is too high the end of the battens gets snared. Sail makers
are not necessarily a good source of info. Many don't have enough
experience to call upon to assist.
I had a Freedom with full battens and lazy jacks. They worked so
well they were never a concern. My present boat, a C+C 29 with
fully battened main and a botched set of lazy jacks from a local
loft will need lots of work. My problem is the upper mount is too
high and the lower block which attaches the line from the boom to
the line on the mast is also too high. With full battens this line
on the boom should form its angle just above the lowest batten.
On non-full length battens it doesn't seem so critical.
Is any of the info in the note earlier in this conference of any
value to either of you?
