DEPTH OF THE CHAIN LOCKER
Measuring the vertical distance (minimum fall) 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 centre of the chain locker.
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
advantage of a 180-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.
