INSTALLATION
2.1
SELECTION OF POSITION FOR THE CAPSTAN
Position of the mooring capstan should be selected
together with positions of fairleads for mooring rope.
The capstan can operate in both clockwise and
anticlockwise direction, depending on how the
connections to the motor are made (refer to diagrams
in Appendix C). However, it is recommended to use it
in one direction only. The direction should be chosen
depending on position of fairleads, to ensure clear
run of the rope from fairlead to the drum. If this is not
possible, turning fairleads should be used to route
the mooring line.
When positioning the capstan, also allow an easy
access to the drive for connecting power supply lines
to the motor. Note that the gearbox can be indexed
through a number of different angles in relation to the
capstan deckplate. Be sure to select the most
convenient arrangement at installation.
A footswitch is the most practical and the safest way
of operating a mooring capstan. To ensure safe
position of the operator while tailing from the warping
drum, footswitches should be positioned at least
500mm (20”) away from the capstan.
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 motor starter (solenoid valves for hydraulic
capstans) should be located in a dry area in close
proximity to the capstan. It must not be located in the
wet environment of the chain locker.
The breaker/isolator panel (DC powered windlasses
only) is selected to provide limited overload
protection for the motor and full protection for the
supply cables. It also provides the means for isolating
the electrical system from the battery.
This should be mounted in a dry place within 1.8m
(72”) of cable length from battery.
This equipment or equivalent is mandatory to meet
U.S.C.G. requirements.
!
Definition of rotation
Clockwise and anticlockwise rotation is
defined as viewed from above the capstans.
Most capstans are used in one direction
only.
!
Use only clockwise rotation for handling
3-ply twisted rope, otherwise problems may
occur in laying the rope.
!
If using the capstan for hauling an anchor
line, make sure the other end of the line is
securely fastened to the boat.

PREPARATION OF MOUNTING AREA
It is of paramount importance that the vessel has
sufficient deck reinforcing and total structural
strength to sustain the loads that can be transmitted
to the mounting area of the mooring capstan. This
should be equal to the loading of the equipment to
beyond breaking strength of mooring lines.
The mounting area for the capstan must be perfectly
flat and rigid. A structural grade filler can be used to
level this area if initial flatness is inadequate. The
capstan should be installed so that lower end of the
cylindrical part of the drum is level with the centre of
hawse ring / fairlead (see Picture 2.2).
Standard units will accommodate deck thickness up
to 90mm (3.5”). Extra clearance models are available
to accommodate deck thickness of up to 315mm
(12.4”). It should be noted that leaving at least 30mm
(1.2”) free space above gearbox will considerably
