Step 6.
Slide the diamond wires into the corresponding slots at the end of the sprea-
ders. Make sure the diamond wire is completely in the slot!
Step 7.
Secure the diamond wire onto the spreader with the thin wire. Do this by
twisting both thin wire ends around each side of the diamond wire. Then
bring the two ends together and twist them into each other. Cut off the ex-
cess thin wire ensuring it is bent neatly onto the diamond wires as to prevent
the wire from tearing the sails.
Step 8.
Measure the spreader rake by placing a sail batten (or something else) on
the diamond wires, directly besides the spreader arm. Then measure the
spreader rake with the tape measure. The pre-bend should be between 35-
45 mm. See the trim sheet for tips. Also check if the spreader bars are per-
pendicular to the mast!
To adjust the spreader rake turn the rake adjuster screws in or out. Make
sure there is no tension on the diamond wires while adjusting! The distance
on both rake adjuster screws should be the same. Always check if the sprea-
der bars are perpendicular to the mast!
