PRODUCT VARIATIONS
There are two options of above-deck arrangements
or “topworks”.
The types of topworks are:
VWC - vertical windlass with chainpipe
VWCLP - vertical windlass with chainpipe, low profile
Each of the above topworks is available as clockwise
or anticlockwise configuration (see description of
Definition of rotation in Section 2.1).

INSTALLATION
2.1
Windlasses of this size will often be installed in
windlass deckplate (Picture 2.4). Be sure to select
SELECTION OF POSITION FOR THE WINDLASS
pairs, giving an emergency backup in the event of
mechanical or electrical failure. In this case one of
the windlasses will normally be retrieving anchor
running clockwise and the other anticlockwise
(Picture 2.1).
Position of the windlass should be selected together
with positions of hawse pipe and spurling pipe.
The deckplate should be installed pointing with its
narrower end in the direction of the incoming chain.
That allows the chain to have maximum
engagement with the chainwheel.
Allow the chain a straight run from the bow roller to
the chainwheel with no more than a 2° deviation
from horizontal (Picture 2.2).
The bow roller should have a vertical groove to suit
the profile of the chain. Its centre line should be
tangentional to the chainwheel. This will align the
chain so that it enters the chainwheel without
twisting.
The fitting of a chain stopper is essential to take the
load off the windlass while the vessel is at anchor. It
must be correctly aligned with the direction of chain
and installed at appropriate height to avoid the
chain rubbing over chain stopper body or pawl.
Make sure the chain stopper clears the anchor
shank.
A tensioner device to tension the anchor into its
pocket is recommended. If the anchor is not snug in
the pocket, it could cause damage to the pocket in a
heavy seaway.
Ensure a minimum of 800mm (32") clearance
between the end of spurling pipe and the chain
piled up in the chain locker (Picture 2.3). This will
assist kinks, which may develop in outgoing chain,
to shake free.
The chain must gravity feed into the locker. If the
chainpipe cannot be positioned directly over the
locker, a heavy wall pipe can be used to direct the
chain to the required area. It is important that the
chain slips through the pipe easily; completely
unaided, sharp corners should be avoided. It may
be necessary to provide the pipe with a bell mouth
or to bell mouth the entrance to the chainpipe from
the locker to assist the free flow of the chain from
the locker.
The chain locker must be of such a size and shape
that the chain will heap up and feed out naturally
without fouling.
If it can be arranged, the chain locker bulkhead
should pass between the chainpipe outlet in the
deckplate and the gearbox. This will keep the
gearbox, motor and power lines dry and away from
flaying chain. Access for servicing from inside the
cabin area can usually be arranged through a
locker.
Note that the gearbox can be indexed through a
number of different angles in relation to the

the most convenient arrangement at installation and
ensure incoming chain well clears the gearbox,
2.2
PREPARATION OF MOUNTING AREA
It is of paramount importance that the vessel has
motor and power supply lines.
To ensure safe position of the operator while tailing
from the warping drum, footswitches should be
positioned at least 700mm (28”) away from the
windlass.
The below deck portion of the footswitch should not
be exposed to water or wet environment and the
breather holes must be kept clear. The arrows on
the footswitches should be arranged to indicate the
direction of operation.
The motor starter should be located in a dry area in
close proximity to the windlass. It must not be
located in the wet environment of the chain locker.
Picture 2.4
Positions of drive, relative to topworks
sufficient deck reinforcing and total structural
strength to sustain the loads that can be transmitted
to the mounting area of the windlass and chain
stopper. This should be equal to the loading of the
equipment to beyond breaking strength of the chain.
The mounting area for the windlass must be perfectly
flat and rigid. Structural grade fillers can be used to
level this area if initial flatness is inadequate.
Mounting area for the chain stopper should be
prepared at the same time. The chain stopper has to
be installed at an appropriate height to ensure that
chain lays horizontally when it comes out of the
chain stopper and into windlass. Maximum allowed
angle deviation in vertical plane is ±2°.
If hawse pipe is angled outboard from deck to anchor
pocket, the chain stopper should also be angled by
half of the angle of the hawse pipe (Picture 2.4). That
will help to reduce twisting of the chain between the
chain stopper and the windlass and ensure good fit
of the chain into the chainwheel. The chain stopper
can be installed vertically if the hawse pipe angle is
less than 4°.
A deck cutout detail drawing is enclosed with these
instructions to assist in marking out all the drilling
and cutting required for installing the windlass.
Before drilling and cutting, check the marked out
area is dimensionally correct and make any
necessary corrections.

• Undo Screws and remove the Deckplate.
• Refer to Appendix B of this Manual and identify
all parts. If any parts are damaged or missing,
contact your Maxwell distributor. Some smaller
parts might not be assembled on the windlass
by the factory, but supplied in a plastic bag in
the packing case.
Maxwell strongly recommends generous application
of a high quality anti-corrosive paste or coating to the
mating sections of main shaft, drive key, flanges,
screw threads, dowels and other surfaces that are
likely to seize after being in contact for a prolonged
period of time.
Also ensure anti-corrosive coating is liberally applied
to the inside wall of the spacer tube.
identifying components and installing them correctly.
Extra care should be exercised when handling
polished parts to avoid any damage to polished
surfaces.
When assembling the parts, apply an anti-seize
compound generously over all screw threads, keys
and keyways, main shaft and inside the spacer tube.
Proceed with installation in the following order:
• After cutting holes for the windlass in the deck,
apply an appropriate bedding/sealing compound
and bolt the deckplate to the deck using
mounting studs, washers and nuts. Tighten them
evenly to 35-40 Nm (25-30 ft lb). The chainpipe
and the pawl, if should already be assembled to
the deckplate.
• Offer up, from below deck, the drive assembly
sliding the main shaft through the deckplate,
taking care not to damage the deck bearing.
• After aligning them correctly, bolt the deckplate
and spacer tube together, from above deck,

using the 3/8” hex head screws and spring
washers. Tighten them evenly to 35-40 Nm
(25-30 ft lb).
• Re-check that the position of the drive assembly
is satisfactory and convenient for connecting
power supply lines to the motor. Also, make sure
that the drive is not in the way of chain coming
into the locker.
• If a chain counter is used, its sensor should be
fitted into the Ø15mm hole in the deckplate,
currently covered with a plastic plug. Make sure
the deck is drilled below for the sensor cable.
See brochure supplied with chain counter for
detailed assembly instructions.
• Slide the emergency crank collar over the
main shaft and then the spring and washer on
top of it.
• Insert the two retention clips into the
groove in the main shaft. Apply some grease to
help keep them in position.
• Apply anti-seize compound generously over the
main shaft and keyway. Insert key into the
lower keyway on the main shaft.
• Assemble the lower clutch cone making sure
it sits nicely on the retention clips (picture 2.5).
Apply Lithium based marine grease generously
to the conical surface of the clutch cone, to
assist with free falling the anchor.
• Put the disc spring on top of the lower
clutch cone, turning its smaller diameter
towards the clutch cone(picture 2.6).
• Install Chainwheel and the remaining disc
spring on top of it, turning its bigger diameter
towards the Chainwheel.
• Install Upper Clutch Cone, after applying
marine grease to its conical surface (see
picture).
• Assemble drum on top of the clutch cone
(VWC models only).

INSTALLATION OF CONTROLS
The windlass can be operated using:
• Deck mounted footswitches
2.7
NOTE TO BOAT BUILDER
Experience has shown that, on long ocean
top quality condition as you received it from Maxwell.
• Hand held pendant controller (single or dual
speed)
• Helm switch
• Chain counter
These control accessories are available from
Maxwell customised to suit your windlass.
It is the choice of the designer/builder to use one,
two or all three of these controls. They are wired in
parallel to the directional valve (for hydraulic
windlasses) or to the starter unit (for electric
windlasses). The controls can work on 12 or 24V
power supply.
If footswitches are used, then an isolator switch for
them must be installed in the wheelhouse, to prevent
operating the windlass by someone accidentally
stepping on the footswitch.
Hand held pendant controller is often the most
convenient way of operating the windlass. Maxwell
offers several variations of pendants, including single
speed, dual speed, single pendant for running a pair
of windlasses, pendants with auxiliary buttons which
can be used for starting chain wash system,
hydraulic pump etc. They are supplied with a plug on
the other end of cable and a matching waterproof
socket, which should be installed on a convenient
location on the deck.
All units are supplied with detailed wiring instructions
to assist installation.
Refer to wiring schematics in Appendix C for control
circuits. All control wiring should be done using no
smaller than 1.5mm² wire (AWG 16).
A manually re-settable, ignition proof 3A breaker or
fuse should be installed on the power supply line for
controls, within 1m (40”) from the main
breaker/isolator. These requirements are mandatory
to meet USCG, ABYC and NMMA rules.
After connecting the power lines, spray all ports and
fittings with anti-corrosive waterproof coating “CRC
3013 Soft Seal” or equivalent.

•
station without maintaining a clear view of it and
having made sure that everyone is well clear of
the windlass, anchor and chain.
• Never use the windlass under power with the
emergency crank collar.
• When engaging the pawl while chain is running,
keep fingers away from the chain. Use clutch nut
lever, underneath and guarded by the chainpipe.
• Always motor up to the anchor position before
retrieving it from the bottom. Do not use the
windlass to pull the boat to the anchor.
• If the anchor is fouled, do not use the windlass to
break it out. With the chain stopper taking the
load, use the boat’s engine to break the anchor
loose.
• When lowering the anchor under manual control,
use the band brake or friction clutch (if fitted) to
control the speed of the chain. Never lower the
anchor without maintaining safe chain speed.
• When the windlass is not in use, make sure the
power supply is isolated, making an accidental
operation thereby impossible.
• Do not use the windlass as an anchoring point
for the chain. Engage the chain stopper when
the windlass is not in operation.
• Never proceed at speed without first ensuring
that the chain stopper is engaged. Also engage
the tensioner to keep the anchor snug in the
pocket.
•

the clutch nut lever in one of the slots on the clutch
nut, and turning clockwise firmly. The windlass is
equipped with a friction clutch, so it can be engaged
in any position (there is no need to match the
position of the opposite sides of the clutch before
engaging it).
• Remove clutch handle.
• Release pawl.
• Disengage chain stopper and chain tensioner (if
fitted). To disengage the chain stopper pawl the
windlass may require momentary jogging in the up
direction.
• The windlass may now be lowered under power
by operating either the hand held pendant control,
helm switch or footswitch.
• When finished, turn off the isolator switch for the
controls.
3.3
RETRIEVING THE ANCHOR UNDER POWER
As a safety feature the windlass will continue to
operate up or down only while the operating
button, toggle switch or foot switch is held in
the engaged position.
Picture 3.1
Engaging the clutch
• Ensure clutch is engaged and pawl is released.
• Remove clutch handle.
• Release chain stopper and/or tensioner.
• The windlass may now be operated to raise the
anchor.
• After retrieving the anchor engage chain stopper
and/or tensioner.
• Turn off the isolator switch for the controls.
This method will normally be employed to lower the
anchor quickly, to lower it in "quiet ship" and in
emergencies (power loss or control failure).
Proceed as follows:
• Tighten the clutch.
• Release the chain stopper and/or chain
tensioner. If the anchor has to be lowered in case of
power loss and pawl on the chain stopper is
engaged and under tension (by chain), to release it,
pull the chain in slightly, either by power or manually.
If there is too much slack in the chain, it might be
necessary to jog the windlass up under power or use
the emergency crank lever. If doing that, make sure
the clutch is still engaged, for safety reasons.
• Slowly disengage the clutch by turning the clutch
nut anticlockwise. Regulate the speed by tightening
to slow (clockwise) or easing (anticlockwise) to
increase speed
When the required amount of chain is out,
•
It is regarded as sound practice to motor over
the anchor position and so reduce chain
tension. This will also help the anchor to break
out, reduce the power consumption and reduce
load on the windlass and deck gear.
! Care should be exercised when docking the
anchor to avoid damage to the anchor pocket.
Jog in the last meter (3-4’) of the chain
carefully seating the anchor home.
! It is considered potentially dangerous to allow
the chain to free fall in an unrestricted manner
- always control the chain speed.
! If jogging under power, ensure the lever is
removed first

mechanism to retrieve the anchor in case of
emergency. It involves operating the windlass
manually under heavy load and extra care must be
exercised when using it to avoid injury.
To use proceed as follows:
• Check that the chain stopper is engaged. If a
chain stopper is not fitted, ensure that the pawl
is engaged with the chainwheel.
• Insert the clutch nut lever in the clutch nut and
release clutch by turning the clutch nut in
anticlockwise direction.
• Insert the clutch nut lever (the end with spigot)
into the emergency crank collar and engage the
spigot with one of the dogs in the chainwheel in
the furthermost forward position (Picture 3.2).
• Pull the lever back as far as possible, bringing
the chain in. Engage the pawl and ease off the
lever.
• Push lever to furthermost forward position and
re-engage with the chainwheel.
• Repeat the cycle until the anchor is retrieved. It
is a very slow process and should be used only
in emergencies.
Picture 3.2
Using emergency crank mechanism
can be operated independently of the chainwheel
and can be used to manage docking lines or a
second anchor. To use in this way, proceed as
follows:
• Engage the chain stopper and/or the pawl.
• Fully disengage the clutch as described in
Section 3.4.
The drum may now be operated independently of
the chainwheel. Maxwell recommends all warping
operations be controlled by the footswitch. This
makes it a one-person operation and offers better
control of the capstan in case of emergency.
Take several turns of the warping line around the
drum and pull on the rope tail with sufficient manual
force to provide good grip of the line to the drum,
whilst operating the footswitch. Make sure the drum
is operated in the same direction as the line is
wrapped around it.
Do not engage more turns on the drum than are
necessary to accomplish the task. Whilst docking,
wind and tide can impose sudden and excessive line
tension. It is recommended to allow slipping to occur
at the drum. This will protect the capstan, docking
! While handling docking lines with the capstan,
everybody has to stay well clear of the lines
and the capstan.
! Take care not to allow “riding turns”. This is
caused by the loaded line climbing on top of
lower loaded coils. A riding turn can only be
removed by paying out to the point where the
riding turn is removed.
