Figure 4-3.Chain swivel.
Chain swivels (fig. 4-3) are furnished as part of the
outboard swivel shot. They reduce kinking or twisting
of the anchor chain.
Bending shackles (fig. 4-4) are used to attach the
anchor to the chain.
Outboard Swivel Shots
Standard and alternate outboard swivel shots also
called bending shots, consist of common links and
fittings as shown in figure 5-4. They are fitted to attach
the 15 fathom shots of anchor chain to the anchor. They
also make it possible to stop off the anchor outboard of
the swivel and break the chain at the detachable link
inboard of the swivel. This allows the anchor chain to
be used as part of the towing gear. Outboard swivel
shots vary in length, but they usually do not exceed 5
fathoms. The taper pins in the detachable links in the
outboard swivel shot are additionally secured with a
U-shaped, stainless steel wire-locking clip (sometimes
called a hairpin). This hairpin, inserted in holes drilled
through the coupling plates, engages a keyway or
groove on the taper pin and is mandatory. (See fig-
ures 4-2 and 4-4.)
Riding, Housing, and Towing Chain Stoppers
Riding and housing chain stoppers consist of a
turnbuckle inserted in a couple of links of chain. A
pelican hook is attached to one end of the chain; a
shackle is attached at the other end. The housing stopper
is nearest the hawsepipe and must be installed outboard
of the swivel; the riding stopper is farther inboard.
These stoppers are secured by the shackles to
permanent pad eyes on the ship's deck Chain stoppers
