INDIA.

WEST COAST.—BOMBAY HARBOUR APPROACH.—LIGHT-VESSEL
ESTABLISHED.

An unwatched light-vessel showing an occulting white light
every 15 seconds—thus, light 10·5 seconds, eclipse 4·5 seconds
— has been established in the approach to Bombay Harbour,
in (approximately) 19° 6′ N., 72° 23′ E. The light has a
luminous power of 1,000 candles, is exhibited 32 ft. above the
water, and visible 11 miles.

The hull of the vessel is painted red with “BOMBAY FLOAT-
ING LIGHT” on the sides. She carries a tower with ball.

CAUTION.—Owing to the mechanism of the light being out
of order, the flashes are not regular or of such long duration ;
they are cut off and may become obscured by the rolling of
the vessel.

EAST COAST.—BAY OF BENGAL.—MADRAS HARBOUR.—
‘RE-EXHIBITION OF TEMPORARY LIGHT.

The temporary fixed red light referred to in former Notice
to Mariners of 1918 has been replaced, and will be exhibited

UNITED STATES.

ATLANTIC AND GULF COASTS.

Former Notice hereby cancelled.

ATLANTIC COAST.

Nets and Defensive Sea Areas.

Vessels approaching a port of the United States may expect
to find patrol vessels some distance off shore as well as close
to the harbour entrance.

All incoming vessels must be identified before being per-
mitted to proceed.

Upon approaching a port or defensive sea area where
vessels are stationed the incoming vessel should obtain from
the patrol a pilot or information that will enable said vessel
to proceed. No vessel should proceed until identity has been
established and permission has been given by the patrol.

Harbour entrance patrol vessels, in addition to the regular
commission pennant, fly the jack forward during the day,
and may show three lights—white, red, white—in a vertical
hoist at night.

Directions from these boats must be obeyed, as they are
in possession of the latest information regarding the nets,
mines, and channels.

Speed limit in defensive sea areas is five knots.

Merchant vessels must show their national colours, and the
International Code signal designating their names. They will
receive pilots or instructions from the patrol vessels.

An incoming naval vessel must exchange recognition sig-
nals, and after having passed the outer limits of a defensive
sea area shall proceed as directed. Should the shore defences
make the demand signal, or other inquiry regarding the
identity of the vessel, the proper answer must be given.

No vessels are permitted to pass through defensive sea
areas except those which have been given authority to do so.
Recognition signals need not be exchanged with vessels on
the inner side of defensive sea areas.

When demand is made by any fort, shore station, or patrol
vessel a naval vessel approaching from seaward shall immedi-
ately answer the demand by making the prescribed recognition
signal.

When the identity of the vessel is already known to the
fort, shore station, or patrol vessel the demand may be
omitted. Coast-defence commanders will consider as hostile
any vessels attempting to enter without making recognition
signals when demanded.

I. BOSTON HARBOUR.

The following regulations have been published for the
information and guidance of all persons having control of
vessels, other than naval vessels, entering the defensive sea
area of the Port of Boston.

The designated entrance to the defensive sea area of the
Port of Boston is the Boston light-vessel. The outer limit
of the defensive sea area of the Port of Boston is a line drawn
from Strawberry Point to Spouting Horn.

Vessels desiring to enter the Port of Boston will, on
approaching the designated entrance, fly their national
colours together with their International Code number and
speak the official pilot-boat stationed between the Graves
light-and-whistle buoy and Boston light-vessel, and there
obtain permission to cross the defensive sea area, which will
be given in the nature of a password or pass letters. Vessels
speaking the pilot-boat will slow down to such speed as will
give ample time to answer routine inquiries from the pilot-
boat. Vessels receiving permission to cross the defensive
sea area will proceed to the vicinity of Finns Ledge buoy and
speak the patrol-boat stationed at that point, giving the
password or letters received from the pilot-boat, and receive
instructions, if necessary, before passing in through the gate
in the submarine net. In case the pilot-boat is not on her
station, or if by reason of thick weather she cannot be seen
by the approaching vessel, the latter may proceed to the
patrol-boat stationed in the vicinity of Finns Ledge buoy.
At that point the authority of the vessel to proceed, or to go
outside and anchor, will be decided by the station patrol-boat.

Vessels will answer hails from patrol-boats within the
defensive sea area by giving the password or letters obtained
from the pilot-boat and answering any routine questions that
may be asked, slowing down if necessary.

No vessel will attempt to pass in through the gate in the
submarine net without first speaking the patrol-boat stationed
in the vicinity of Finns Ledge buoy. After passing in through
the gate in the submarine net all vessels will proceed to the
station vessel on the inner limits of the defensive sea area—
i.e., half a mile west of Deer Island light—and receive per-
mission to proceed, or to anchor, and any other instructions
that may be necessary.

Vessels desiring to cross the defensive sea area outward
bound will speak the station-boat at the inner limits—i.e.,
half-a-mile west from Deer Island light—and there obtain
permission and the necessary password or letters and in-
structions as may be necessary.

Vessels crossing the defensive sea area without the pass-
word or letters may be required to return to the station-boat
—i.e., inbound, the pilot-boat stationed between the Graves
light-and-whistle buoy and Boston light-vessel; outward
bound, to the station-boat half a mile west of Deer Island
light.

Speed of vessels within the limits of the defensive sea area
is limited to 5 knots.

Naval vessels will use such force as may be necessary to
insure compliance with the above regulations.

II. NEW YORK AND APPROACHES.

Vessels bound to New York from Chesapeake Bay, after
reaching the parallel of lat. 40° 14′ N., should keep to the
eastward of a line drawn in a 0° (N. 10° E. mag.) direction
through Ambrose light-vessel until Scotland light-vessel
bears 293° (N. 57° W. mag.), when course may be shaped for
the entrance.

The area to the southward and westward of the lines
mentioned above is entirely prohibited to vessels from sun-
rise to sunset; at night this area is not restricted.

Net N 31 is across The Narrows in New York Bay at Fort
Hamilton, where the U.S.S. “Amphitrite” is moored as
station-ship. The gate is at the western end. All vessels
must have a regular licensed pilot, except public vessels and
such coastwise shipping as may be authorized by law not
to take local pilots.

Vessels must comply with the regulations for crossing
defensive sea areas while in these waters. Vessels inward
bound or outward bound approaching The Narrows must
proceed at a moderate speed and keep close to the western
side of the channel, passing to the westward of the light-
buoy off Quarantine. They must be identified and receive
instructions from the station-ship before proceeding.
