Note that if you want to use an existing sail, it will need some modifications.
• The luff length needs to be adjusted.
• A luff tape is required. The luff tape must be compatible with the Furlex luff extrusion geometry.
• Use webbing loops at the sail head and tack instead of grommets (cringles). The sail will then form tightly
round the luff extrusion when furling, and achieve a better shape when reefed.

It is most important that the halyard swivel is located so that the halyard satisfies the
10–15° angle requirement. If the sail prevents the swivel from reaching the correct
position, the luff length needs to be adjusted.
IF THE SAIL IS TOO LONG: Shorten the sail, e.g. in conjunction with changing to a
luff tape compatible with Furlex.
IF THE SAIL IS TOO SHORT: Lengthen the sail by means of a HMPE or wire
pendant fitted to the head of the sail. Attach the pendant directly to the sail to prevent
unintentional removal, loss or exchange.
