Flexible feeder limit line fitting instructions
The limit line assembly consists of two stainless steel termination blocks and a fixed length
of Spectra
TM
line which passes through the eye on the forward face of the luff feeder.
To install the limit line termination blocks on the mast, position the port and starboard
blocks at an equal distance from the aft face of the mast.
The limit line should be loose
enough to allow the track to flex port and starboard but not aft.
With that in mind, the
termination blocks should be installed on the mast sides as shown in the diagrams 4 & 5.
The termination blocks are installed using the 1/4-20 FHMS provided, use an F or 3/16”
drill. The knot in each end of the limit line must be pushed out of the termination block to
expose the fastener hole. This will allow marking of the mast for drilling and tapping, as
well as installing and tightening the screw. This may require flexing the track forward to
install the second termination block. A piece of light line, tied around the mast and luff
track, may be handy here to hold the track in the forward flexed position.
Each installation is a little different, and the desired amount of flex has to be determined by
hoisting and furling the sail. The furling operation should be done several times with eyes
on the luff of the sail. Ensure that the 87
o
boom angle is correct, then watch as sail the rolls
into the boom. Furling should be checked at different angles to the wind, since this is the
true test of the flexible feeder setup.
Once the termination blocks have been
installed on the mast, the only way
to affect the amount of flex in the
unsupported portion of the luff track
is to change the length of the limit line.
If less flex is deemed necessary the
line can be shortened.
If a longer line is required for
additional flex, Spectra
TM
line can be purchased
from your local chandlery.
Use a figure eight stopper
knot in each end then trim
the ends as necessary.
