100sqft Balanced Lug, designed by John Welsford
The design of this sail can be found
These are the two sails I've almost finished. Ever since I saw
striped polytarp, I've wanted to make a sail from it. I wish the
stripes were wider - like 8" wide or so, but what are you gonna
The hardest thing about making sails is having enough space. The
damn leech on these is 15' 9". Since it rains from Ocotber
to April, I have to do my work inside - which the dogs see as their
own private domain.
Schnauzers are loyal, dedicated, loving, and energetic. None of
those things make them good helper dogs.
I am using reinforcement patches on these sails - layers of material
to make the corners stronger. Each corner has 3 additional layers
of fabric, and the hem is folded over 3 times. It is a real bear
getting the stripes to match up - each patch is custom fitted.
You can barely see the rope edge here - I run it around most of
the perimeter of the sail to help keep the grommets from pulling
out under stress. Polytarp is stretchy, so you have make sure the
sail doesn't deform with use. You can also see my grommet patches
- the white triangles. Again - just reinforcement to keep deformation
to a minimum.
The sails have 3 reef points so I can reduce the sail size when
the wind picks up. Netties are the strings that are used to gather
up all the loose sail material when the sail is reefed. To keep
the netties from ripping out the middle of the sail under stress,
I sewed on these 'nettie patches' - and 8" square folded in
half twice to make a patch 4 layers thick and 4" square. Sew
the patch to the sail, then netties on each side of the sail and
you are done (much easier said than accomplished.
