DEPTH OF THE CHAIN LOCKER
Ensuring that the vertical distance, (minimum fall), between the underside of the deck and the top of
the completely stored and heaped anchor rode in the locker will assist in determining the installation to
suit your vessel. Refer to the fall depth diagrams and the options detailed below. It is also
recommended that the chain be directed to the center of the chain locker. (See also water protection
diagram on page 15.)
If your vessel does not meet the minimum fall requirements for a vertical windlass, contact your Muir
retailer.
Vertical Windlass:
The running gear, gypsy
and capstan are positioned above the
deck with the motor and gear drive
below. Vertical windlasses operate at
best with greater anchor rode fall than
the horizontal windlass and a minimum
fall of 300mm from top of stacked anchor
rode is recommended. This is particularly
important if using nylon line, which does
not fold and stack as well as chain.
Vertical windlasses minimise deck
intrusion and the modern curved lines of
the Muir windlass enhance the look of
any vessel. A vertical windlass provides
the advantages of a I80-degree wrap of
the anchor rode around the gypsy.
Horizontal Windlass:
Fully enclosed,
above deck, this style is usually preferred
where locker space is limited or
additional fall is required. The motor and
gear drive is fully enclosed in the housing
with nothing protruding below deck. The
horizontal windlass operates with
optimum anchor rode fall of at least
300mm from the top of the stacked
anchor rode, and due to the horizontal
orientation of the gypsy higher above
the deck there is additional fall provided.
These units are ideally suited for vessels
with less locker space.
