can be readily disassembled whenever it is desirable to
break the chain.
As the chain comes aboard, it passes along the deck
on metal flash plates, over the wildcat, and down into
the chain locker. Each chain goes into a bin called a
chain locker, as shown in figure 7-1. Its bitter end is
secured to a ring bolt on the bulkhead of the chain
The Navy uses two types of anchor windlasses for
lifting the ships anchorthe vertical shaft type and the
horizontal shaft type (fig. 7-3). The vertical shaft type is
used on most combatant ships. The horizontal shaft type
is used on amphibious and auxiliary ships. Both types
are equipped with wildcats, which engage the links of
the anchor chain. The wildcat may be disengaged when
it is desired to use the capstan (vertical type) or the
gypsy heads (horizontal type) for handling lines or wire.

mistakenly called the gangway. However, gangway
actually means the opening in a bulwark or life rail that
gives access to a brow or an accommodation ladder. An
accommodation ladder (fig. 7-4) consists essentially of
an upper and a lower platform connected by a ladder.
The lower end is supported, raised, and lowered by a
block and tackle (called falls) and is usually suspended
from a davit.
Brow is the Navy term for gangplank. Brows are
ramps used between ships and between a ship and pier.
They may be simply two or three wooden planks
fastened together, or they may be elaborate affairs with
handrails and wheels at one or both ends to prevent a
ships motion from unduly affecting the positioning of
A ship is moored when its made fast to a buoy,
when its between two buoys, when its between two
anchors, or when its secured by lines alongside a pier or
The lines used in mooring a ship alongside a pier are
shown in figure 7-5. Well in advance of mooring, the
lines should be faked down, fore and aft, each near the
chock through which it passes in preparation for passing
the line. You will learn about the procedure for faking a
