The sail
The luff extrusion is asymmetrically shaped to help overcome initial resistance when starting to furl. Do not use
too heavy sail cloth in the luff area.
To improve sail shape when reefed and to reduce draft. ”Luff foam” may be used along the luff. The foam should
not be placed closer than 50 mm (2”) from the front edge of the luff as it will then increase initail reefing resis-
tance.
Sail dimensions
We recommend maxium 8 mm (5/16”) diameter luff-rope/luff-tape (maximum 7 mm (9/32”) hard line).
Luff groove dimensions are shown in fig. 10.2.
Head and tack tapes should be of soft quality which can foald easily. Do not use metal eyelets on them.
The clew cringle must not be thicker than 14 mm (35/64”) in order to fit the outhaul block.
