5.3 3 Routing the furling line
The illustration below shows of principal arrangement of furling line routing inside a anchor well to
achieve maximum furling performance. The turning block inside the anchor well and the sheave box
required to lead the line through the deck are not included in the Furlex package as these parts must be
individually adopted for each boat.
It must be possible to belay the furling line securely. A block with a Cam-cleat works
well when securing a reef, but is unreliable if the boat is left unattended.
The line should then be secured on a normal cleat for safety reasons. We recommend a single
turning block in combination with a cleat.
If the furling line is accidentally released, the sail may unfurl and flap out of control.
This will cause damages beyond repair.

The final turning block by the cockpit is not included in
the Furlex kit. This needs to be matched individually to
each boat depending on the attachment points, the line
arrangement chosen and possibly also the type of other
blocks on the boat. We recommend a swivel block which
is free to self align. The maximum working load of the
block should not be less than:
404TD ø12: 17kN
404TD ø14: 25kN
The line should be led aft to the cockpit via the lead blocks included in the Furlex package.
The lead blocks are mounted on stanchions and the pulpit. See fig. 5.4.a.
The furling line must enter the line drum perpendicular to
the forestay. There must be at least 300 mm from the drum
to the first tuning point of the line to make the line
furl evenly on the drum
Blocks with large sheaves on roller bearings are recommended
to minimize friction losses.
Strength requirement. To cope with the loads for which the
Furlex system is designed, the turning block below deck
and through deck passage sheave house must have a safe
working load of not less than. 404TD ø12: 12kN
404TD ø14: 18kN.
Push the line cover upwards and adjust it so that the furling
line enters the drum without chafing the cover. Tighten the
screws (A) fully to lock cover from rotating. Do not over-
tighten. (See Chapter 3.4).
