To ensure safe position of the operator while tailing
from the warping drum, footswitches should be
positioned at least 5
00mm (20”) 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 (solenoid valves for hydraulic
windlasses) 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.
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.

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 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 2.5). 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.
The hole for mounting band brake guide (where
applicable) should be marked and drilled after
assembling the band brake on the windlass.

Boats with steel/aluminium construction.
It is very important to insulate the deckplate from
the boat with a non conductive gasket.
Mounting studs and fixings under the deck
should be insulated. Anchor and chain should also
be insulated, including rubber lining, chain locker
and fixing for the end of the chain to the hull.
Without these precautions severe electrolysis can
occur.
It is not necessary to separately earth the
Windlass, as the electric motor is of the isolated
earth type.
