When the
Master
has decided on the need to anchor ship and has prepared an anchoring plan with the
navigating officer or officer on watch, he
shall
brief the officer or other responsible person who is to supervise
the anchoring operation on the focsle. The
Master
shall
discuss his intentions as to how the ship is to
approach the anchorage and any anticipated manoeuvres prior to and during the anchoring operation. The
officer
shall
be made aware of the depth of water the ship expects to anchor in, the anchor to be used, the
amount of cable to be paid out, the method of paying out the cable, the strength and direction of the tide or
current, the nature of the bottom, and the possible affect of any wind.
The means of communication between the focsle and the bridge
shall
be established together with the back
up method if the primary system fails.

When the
Master
calls anchor stations the officer or other person supervising the operation
shall
discuss the
anchor plan and safety procedures with the other members of the anchor party. Ideally the anchor party
should
consist of at least the supervisor and two others. When a complex anchor operation is to be carried
out, additional personnel
shall
be required. Each member of the anchor party
shall
wear suitable clothing,
safety shoes, gloves, a safety hat, and goggles. At night, each member of the party
shall
also carry a suitable
torch.
The anchor party
shall
make the focsle ready. The means of communicating with the bridge
shall
be tested,
both the primary and by secondary methods. All instructions or reports given by radio between the bridge
and the focsle
shall
include as a prefix the ships name.

or
During periods at anchor regular inspections of the focsle
shall
be made. A check on the application of the
brake and position of the guillotine
shall
also be made.
At changes in direction of tidal stream a careful watch
shall
be maintained from the bridge, and if necessary
the focsle, to detect any signs of dragging.
The anchor lights and shape
shall
be displayed in accordance with the requirements of the Collision
Regulations.
If restricted visibility occurs during the period at anchor then the appropriate sound signals
shall
be made. If
there are any problems with the audibility or timing of the automatic signals then the appropriate signals
shall
be made manually. If necessary, the Officer on Watch
should
also make use of the additional sound signal
on the whistle to give warning of the ships position to an approaching vessel. Officers of the watch
shall
be
reminded in the
Masters
written orders of the need to make the proper visual and sound signals while the
ship is at anchor.

Should
the
Master
decide to veer more anchor cable then this
shall
be done with considerable care. It may
be preferable to veer the cable under windlass power rather than controlling it on the brake. The cable
shall
not be slacked back in large amounts as this may result in the excessive weight coming on the cable as the
ship brings up, with the possibility of parting the cable.
