SELECTION OF POSITION FOR THE WINDLASS
Position of the windlass should be selected together
with positions of the hawse pipe.
Allow the chain a straight run from the bow roller to
the chainwheel with no more than a 2° deviation from
horizontal (Picture 2.1).
The bow roller should have a vertical groove to suit
the profile of the chain. 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 600mm (23") clearance
between the underside of deck and the chain piled up
in the chain locker (Picture 2.2). 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.
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 (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.
