Page 12: Assembly Below Deck
3.4 Assembly below deck The lower bearing assembly can be fitted below deck inside an anchor well. The advantage is that the sail’s luff length is maximized and the access around the forestay is improved. The disadvantage is a more complicated route for the furling line, increasing furling resistance. The diagrams below illustrate various methods of installation. -

Page 22: Halyard Routing
5 Halyard routing The angle between the halyard and the forestay must be 5 - 10° - see fig. 5.4.c. If this angle is less, the halyard may wrap around the luff section when the sail is being furled, possibly damaging the halyard and the luff extrusion. -
Page 23: Halyard Sheave Box
5.2 Halyard sheave box A sheave box can also be fitted to the mast to meet the 5-10° requirement. The sheave box will not damage the halyard, nor is it worn by the wire. Installation is more complicated but the box will eliminate the need to replace the halyard leads in future as above. - Page 24 For the halyard routing to work properly, the halyard swivel must be in the correct position to achieve the required angle of 5 - 10°. If the sail does not have the required luff length, this needs to be adjusted . (See Sail, 7.1) 10°...

Page 34: Sailing With Furlex
11 Sailing with Furlex 11.1 To hoist the sail The forestay must be properly tensioned each time the sail is hoisted. You should therefore tension the backstay and any running backstays before hoisting the sail. Tension the forestay for hard close-reach sailing before the sail is hoisted. If the sail is hoisted firmly tensioned before the forestay, this may put excess strain on the halyard, halyard swivel and sail when the forestay is tensioned afterwards. -
Page 35: Unfurling The Sail
If the furling line exits on the port side of the line drum, the sail should be hoisted in the starboard groove. If the line exits on the starboard side, use the port groove. Hoisting the sail in the ”right” groove reduces initial resistance when furling the sail, which then has less of a ”fold”... -
Page 36: Furling The Sail
11.3 Furling the sail 1. Release the windward sheet and ensure that it can run freely. 2. Furl the sail by pulling the furling line. Release the leeward sheet but keep a little tension on it, for example by placing a turn around a winch. It is important to furl the sail tightly and evenly, as a sail which is furled too loosely can blow out a little in strong winds. -
Page 37: Reefing
12 Reefing The size of the working sail area is infinitely variable with a jib furling and reefing system. Even if the sail is designed as a furling sail incorporating foam etc. and the Furlex system is equipped with a ”free turn”... -
Page 38: Setting A Reefed Sail From The Furled Position
12.3 Setting a reefed sail from the furled position You will achieve the best sail shape by first unfurling the sail completely and then reefing down … to the appropriate size. Pull in the furling line and keep the sheet well tensioned. The sail will then form a tight roll and its shape will be improved. -
Page 39: Furlex For Racing
13 Furlex for racing Many racing yachtsmen have exploited the advantages of the jib furling and reefing system … with reat success. The sail can be partly furled before the start, giving good visibility and easy manoeuvring of the boat. Just before starting, the sail is unfurled and the boat crosses the line under full sail. -
