Tension the diamond turnbuckle until you
get your required prebend (base 30 on the
Loos Gauge).
How to measure prebend:
Prebend is defined in this case as the distan-
ce between the trailing edge at the spreader
and a 2 mm dynema line pulled between the
upper most point and lowest point of the
luff track (see pictures). When measuring the
prebend the mast supports shall be placed
at the winch and at the first reef point. Pull
the string tight by hand and use the cun-
ningham friction ring as purchase.

Make sure the knot for the gennaker halyard
lock is tight and stitched together. The tail of
the knot should be short, othervise it can get
caught in the top furler.
Attach the gennaker halyard lock to the soft
schakel on the mast. Run the halyard below
the sheave at the front end of the mast, and
above the sheave closest to the sail track and
down to the clutch.

How to check the spreader angle:
Pull a shock cord tight between the spreader
tips. The string should be pulled just above
the end fitting on top of the diamond stay.

The dyneema soft schakel for the
gennaker halyard lock has to be inspec-
ted each time before sailing.
IMPORTANT!
Measure the distance between the string and
the trailing edge of the mast straight down
from the shock cord. Standard measurement
is 190mm. A halft turn on the turnbuckles gi-
ves approximately a 5mm change in spreader
angle.

Take out the main halyard sheave, run the
halyard and put back the sheave. Pull down
the halyard to the goose neck.
