2 SAFETY INFORMATION
Safety standards and certifying bodies
require peremptorily that, during the
standing of the anchor, the load must be
held by a chain stopper or a high
resistance fixing point.
The user is responsible for guaranteeing
that during navigation the anchor is
properly stowed and fixed. This
precaution is more important when the
navigation speed is higher and sea
conditions are worse. Indeed, an anchor
paid out by mistake during navigation
can have very serious effects.
Considering its position and not always
frequent use, the anchor windlass is
particularly exposed to oxidation and
corrosion risk; therefore, it is necessary
to arrange a constant inspection of its
parts and a due maintenance.
Make sure to have read and understood
every part of this manual before
proceeding with installation and use.
Only persons who know how to operate
should be authorised to use the anchor
windlass. Should there be doubts on its
installation or use, refer always to a
skilled consultant.
•Anchor windl
asses used in an
inappropriate way can cause damages
to persons and/or things.
• Pay the utmost attention during the
use of powerful equipment.
• Even the most careful use can be a
source of damages, even serious.
• Lofrans products are supplied
exclusively for recreational nautical
use. Lofrans declines all responsibility
for improper uses.
• Pay the utmost attention so that arms,
legs, fingers, hair, and clothes do not
get entangled in the chain or gipsy.
• Before operating the capstans, make
sure that there are no persons in water
in the vicinity.
•• hen the capstan is not used, the
• The anchor windlass must never be
used as mooring point. The load must
always be held by a specific leat or
solid point.
• The capstan must not be used for
functions other than paying out or
weighing the anchor.
• The chain must never be used on the
warping drum.
• The system must always be protected
by a suitable circuit breaker.
• Disconnect always the circuit through
the circuit breaker when the anchor
windlass is not in use.
2 SAFETY INFORMATION
anchor must always be fixed to a solid
point in order to avoid damages.

3.4 General requirements for
installation
In order to operate the anchor windlass
correctly, it must be installed to meet
the following conditions:
– %RZUROOHUKHLJKW: it must be such
to guarantee a chain inclination lower
than 90 degrees.
 – The SDUDOOHOLVP between deck
floors must be guaranteed; should it not
occur, duly compensate the difference.
– &KDLQORFNHUGHSWK: the chain fall
into the chain locker must be such that
when the chain is completely stored,
there must be a minimum of 300 mm.
between the underside of the deck and
the top of the heaped chain.

3.5 Prevention from electrolysis
For aluminium boats, it is essential that
the anchor windlass be insulated from
the deck through a non-conductive
gasket (not supplied). In addition, it is
important that also the anchor and the
chain be insulated from the hull,
including chain locket and fixing
systems.

3.6 Installation
–Place carefully the drilling template
on the deck, by ensuring the FRUUHFW
DOLJQPHQW with the bow.
 - Mark and drill as indicated in the
figure. Let the edges of the holes sharp,
while the edge side of the holes of the
chain towards the bow must be
smoothed for an angle of 45° degree.
- Place carefully the upper part of the
anchor windlass on the deck.
Note:
It is recommended to seal the base of
the anchor windlass to the deck by
means of silicone glue.

4.1 Lowering the anchor
 – Make sure that the clutch is
tightened and then disengage the chain
stopper or safety stops.
 – Disengage the clutch gradually
through the manoeuvre handle.
Note: to adjust the descent speed of the
chain act, through the handle, on the
clutch. By turning it clockwise, the
braking speed of the chain will increase
(until complete stop), while by turning
it anticlockwise, braking will be
reduced.
 – Fix the chain (or the rope) to a
strong point.

4 USE OF THE WINDLASS
4.2 Weighing the anchor
 - Make sure that the clutch is well
tightened.
 – Disengage the chain stopper and
safety stops.
 – Insert the manoeuvre handle into
the hand-wheel (506) and turn
clockwise by overcoming the strength
of the spring contained in the reducer.
In case of deep sea, the effort will turn
out to be significant.
– Fix the chain with the chain stopper.
In this way a potential damage of the
anchor windlass will be avoided as well
as unexpected chain releases.
4 USE OF THE WINDLASS
4.4 Use of the warping drum
The warping drum can be used
regardless of the gipsy, to help the
mooring manoeuvres.
 – Make sure that the anchor is
appropriately blocked.
- Disengage the clutch. This operation
will make the drum independent of the
gipsy.
 – Turn FORFNZLVH around the drum
with three laps of rope.
 – By keeping the end of the rope,
insert the manoeuvre handle into the
hand-wheel (506) and turn clockwise by
overcoming the strength of the spring
contained in the reducer
 – Once the manoeuvre is ended,
remove the rope from the drum and
fasten it to a bollard.

4.5 Notes for use
During mooring, the load on the chain
can be very high due to current, wind
and waves.

 – By paying out the chain, it is
necessary to manoeuvre so that the
chain is laid down on the seabed
without heaping on itself.
 - To ease the recovery and not
overloading the capstan, steer up in a
way that the boat slowly moves on the
vertical of the anchor.
– When the anchor is in the vicinity of
the bow roller, slow down the recovery
to check at best the insertion of the
anchor into the seat.
