Instruction Manual
2.2 Additional Requirements
Each capstan installation requires :
a. A solenoid for a single direction installation. (Unless the
High Load Foot Switch only is used)
b. A control switch (or switches) by preference.
c. A breaker/isolator for overload protection which can also be
used as a main isolating switch. (Simpson-Lawrence
recommend the breaker/isolators listed under 3.0
Accessories)
d. The following tools:
Capstan Installation
Flat Blade Screwdriver
10mm (3/8") Diameter Drill
13mm A/F (1/2") Spanner (Wrench)
Jig Saw or Trepanning Tool
Wiring Installation
Flat Blade Screwdriver
Crimping Pliers / Wire Stripper
13mm A/F (1/2") Spanner or Socket
8mm A/F (5/16") Spanner or Socket
e. Marine grade silicone sealant. DO NOT use permanent
adhesive/sealant.
f. Suitable electrical cable and crimp terminals.
2.3 Electric Cable Selection
To achieve the best performance and safeguard your electrical
system, it is essential that any electric capstan is fitted with
sufficiently large diameter cable to cope with the current draw
imposed upon it and, to keep the voltage drop within acceptable
limits. In any circumstance, voltage drop due entirely to cable
resistance should not exceed 5%, roughly 0·5V for a 12V
installation and 1·0V for a 24V one.
The following tables give recommended cable sizes. The
recommendations are based on the total length of cable
required, from the battery to the capstan and back to the
battery, following the route of the cables. (See the Wiring
Diagram for the definition.)
DO NOT confuse Cable Length with the length of the vessel!

5.1.6 Longer Studs
For thicker than standard decks, simply fit longer studs as
appropriate (Thread M8 x 1.25). Studs to special lengths may
be obtained from Simpson-Lawrence Engineering Limited.
5.2.0 Wiring
5.2.1 General Recommendations
Warning! Carefully check to ensure that the capstan motor is
wired to correct polarity. It is possible to damage the gearbox
if the motor is wired to the wrong polarity.
The wiring system should be of the two cable fully insulated
return type, which avoids possible electrolytic corrosion
problems. Most modern installations are negative return
(negative earth) but polarity should be checked.
Solenoids should be mounted as close to the battery as
possible, in a dry location using the mounting holes provided.
Under no circumstances should solenoids or solenoid control
boxes be installed in chain lockers or similar damp or semi
exposed areas.
Overload protection must be built into the capstan wiring
circuit. This protects the wiring and prevents undue damage to
the capstan motor, in the event of it being stalled by an
excessive load in service. It is advisable to site the Breaker/
Isolator in a dry, readily accessible place, as it must be
manually reset should an overload occur that causes it to trip
to the OFF position.
If you are NOT using the Breaker/Isolator recommended, an
alternative MUST have identical characteristics.
NB: Crimp terminals should be used on all wire ends for good
electrical connections.
5.2.2 Control Switch Installation
Follow the mounting instructions supplied with the switch.
Remember when using more than one control switch, it is
important to their correct operation, that they are wired in a
parallel circuit.
5.3 Test
Immediately after installation, it is recommended that the
capstan is tested to ensure it functions correctly in all modes,
e.g., forward, reverse and manual operations should be tested.
5.4 Protection of Below Deck Parts
Check all terminals or connections are firmly secured. Coat
ALL below deck surfaces, including the terminals, with rubber
or plastic type paint (automotive underseal is one convenient
way) OR wrap completely in self amalgamating tape OR coat/
protect in a similar way with some other system suitable for a
marine environment.

5.0 INSTALLATION
5.1.0 Fitting Capstan To Deck
5.1.1 Preparation
The capstan must always be mounted vertically. DO NOT
mount capstan in a horizontal direction as oil will leak from the
gearbox and the capstan will wear out prematurely. If the deck
top is uneven a suitable mounting pad may be required to take
up camber or sheer. Decks which are thin, of foam or balsa
laminate construction, will require a backing piece in order to
spread the load which will be applied locally to the deck while
the capstan is in use. Care must be taken if the deck is of
uneven thickness and a mounting pad and/or backing piece
fitted that the top and bottom surfaces are parallel for optimum
clamping.
5.1.2 Position of Capstan
Select a site for the capstan on the deck that is a comfortable
position for the operator to tail rope off the drum and preferably
feed rope straight into the storage area. A position for the
switch should be found that makes it accessible to the capstan
operator’s foot or knee.
5.1.3 Access
Allow for access to the top of the drum during maintenance.
5.1.4 Mounting Template
Place the mounting template in the desired position. Drill a
clearance hole for the motor to pass through as detailed and
six 10mm (3/8") holes for the studs. The studs supplied suit
decks and mounting pads up to 75mm (3") thickness.
5.1.5 Fitting
Place the capstan and studs through the holes in the deck,
when satisfied that all is correct, fit any packing, the clamping
ring, the nuts and washers, and tighten evenly and firmly using
a 150mm (6") long spanner.

6.0 OPERATING INSTRUCTIONS
6.1 Safety First!
Your Simpson-Lawrence Pacific capstan is a powerful piece of
equipment and should be respected as such. Keep young
children and observers, who are unfamiliar with anchoring
procedures, away from the operating area when in use. To
avoid personal injury, ensure that fingers, limbs and clothing are
kept clear of the rode and windlass during operation. Always
ensure there are no swimmers nearby when dropping your
anchor.
Always keep the Isolator switch OFF except when in use.
6.2.0 Hauling In
6.2.1 Warping
Anchor warp should be laid onto the drum, two or three turns in
a clockwise direction. The operator should stand (or kneel) in a
comfortable position to activate the deck switch whilst tailing the
warp behind and into the storage area, if possible.
6.2.2 Apply Tension
Apply a light even tension to the warp before activating the
switch. If very heavy pulls are necessary apply power in short
bursts of about 10 seconds duration. The speed of hauling
depends on the load on the anchor and will increase after the
anchor breaks free.
6.2.3 Caution!
Should the capstan stall, switch off and wait a few seconds
before trying again. If the recommended breaker/isolator has
tripped, it will require to be manually reset before the capstan
can operate again. It is important to the future, good
performance of the capstan's motor that the capstan is not
allowed to stall for more than a few seconds and therefore,
sensible to avoid stalling your capstan whenever possible.
6.2.4 Recovery
On retrieval, always remember to secure your anchor
independently of the capstan so as to prevent accidental
launch when under way.
6.2.5 Caution!
Chain may be run over the capstan if necessary but marking of
the drum will occur.
6.2.6 Power off
Turn the power isolator OFF after use.
6.2.7 Warning!
Serious damage can be caused by incorrect assembly and
your guarantee may be invalidated as a result. Always
proceed with care. The Pacific family of capstans have been
designed for ease of installation and removal. It should not,
therefore, be necessary to remove any parts other than the
deck clamping ring, nuts and washers.

7.0 IMPORTANT USER INFORMATION
Classification Societies require that a vessel lying to anchor
should have its rode held by a chain stopper or equivalent
strong point as capstans are not designed to withstand the
loads generated under storm conditions. This rule should be
applied to all craft!
At all times it is the responsibility of the boat user to ensure
that the anchor and rode are properly stowed for the prevailing
sea conditions. This is particularly important with high speed
power boats as an anchor accidentally falling into the water
whilst under way can cause considerable damage.
An anchor capstan is mounted in the most exposed position on
a vessel and is thus subject to severe atmospheric attack
resulting in a possibility of corrosion in excess of that
experienced with most other items of deck equipment.
As the capstan may only be used infrequently, the risk of
corrosion is further increased.
When the windlass is mounted in an anchor well with a closing
lid, due to lack of ventilation and consequent high saline
conditions the rate of corrosion is accelerated. It is essential
that the capstan is regularly examined, operated and given any
necessary maintenance. This is of even greater importance
when the capstan is installed in an anchor well!
8.0 MAINTENANCE
8.1 General Recommendations
Isolate the capstan electrically, before carrying out any
maintenance work. After the first two or three anchor
recoveries, check that the capstan is still fastened tightly to the
deck as it should now be bedded-in.
Every three months, unscrew the drum cap top (Part no. 6)
using a broad bladed tool. As the cap may be stiff, a good fit in
the slot is advised to avoid damage to the cap. Apply two
shots of grease to the grease nipple under the top cap. A
smear of grease around the seat area of the top cap will ease
future removal.
Regularly wash down the above deck parts of your capstan
with fresh water.
Ensure that all below deck parts are kept dry. The gears and
gearbox bearings have been lubricated for you and require no
regular attention. It is recommend that the gearbox and motor
exteriors are regularly treated with a water repellent spray
when mounted exposed within a chain locker.
Examine all electrical connections for possible corrosion.
Clean and lightly grease as necessary.
8.2.1 Winter Laying Up
As with all items of marine equipment poor installation or
neglect is often responsible for damage caused during the
winter lay up period. Given correct installation and
maintenance your capstan will require little attention prior to, or
after, winter lay up. Check between the deck plate and deck
for signs of water ingress. Should it occur, remove, clean and
reseal the deck plate. If necessary, replace 'O' ring seal.
