Top edge of drum at deck level.
Large deck hole required for line drum.
Furling line led aft via turning block and
inset deck sheave box, then aft along the
deck.
Tack snap shackle at deck level.
Requires smaller hole in deck.
Furling line leads forward to an inset deck
sheave box, alternatively aft via a block +
deck sheave box.
Lower bearing assembly in the bottom of the
anchor well. Long webbing band attached
around the extrusion.
May put too much strain on the furling
extrusion.

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.
For the furling line to be wound evenly onto the line drum, the first turning point must be at least
500 mm (19 11/16”) away.
The tack should be located as close to deck level as possible.
Regardless of which option is chosen, the Furlex-system must always be kept clear of the deck
well’s inside surfaces.
Avoid routing the line through an integral deck conduit, as this will increase the friction on the
furling line.
Use a large ball-bearing block to minimize friction losses.
The anchor well must be well drained.
To avoid damage to the Furlex-system and the boat, the system must never be allowed
to come into contact with the edge of the deck or well when sailing.
