•
Place another trestle under the end of the leading edges and remove the trestle from the cross-
tube end area.
•
Remove the nose weight.
•
Slide the nose of the sail over the leading-edges/cross-tubes junctions and the keel.
•
Pass the hang-bracket through the nose of the sail. You may need to rotate the hang-bracket in
order to pass the sail over it.
•
Check for the keel reaching the hang-bracket position on the underside of the sail. The keel
needs to come out of the sail at this position and then back into the flat keel pocket at the rear
of the sail, Figure 5-14. It may help to spread the wingtips by about 1m around this point.

•
The keel should emerge from rear end of the keel pocket as the sail is pulled up to the nose.
•
The sail should now be completely on the frame, with the keel protruding from the keel
pocket and the wing tips close to the ends of the sail. Check that all the tubes have passed
down the leading edge side of the membrane.
•
Now remove the protective packing from the ends of the keel and leading-edges.
3. Top Rigging
•
The upper rigging is attached to the king-post head and comprises two upper wing wires, the
upper forward rigging wire, and a short part of the rear upper rigging wire.
•
Lay out the upper rigging with the king-post upper fitting laid on top of the sail close to the
nose.
•
Thread the upper forward rigging wire down through the opening in the sail close to the nose
and to the rearmost bolt on the nose plate above the keel.
•
Apply threadlock and tighten the nut, while still allowing rotation of the tang as usual.
•
Insert the upper wing wires through the openings in the top surface of the sail close to the
cross-boom/leading edge junctions.
•
The wing wire can now be attached on top of the cross-tube as per Drawings
UO28245-
M050 .
•
Apply threadlock to bolt, screw
BHC 8-96/11 (B090960),
and tighten gently, allowing
rotation of the cable tang.
•
Pull the lower wing wires through the opening in the lower sail surface.
