7. Environmental
Considerations
• Winds: Strong winds are frequent from November through April.
Sustained winds 17 to 33 knots occur 3 to 5 percent of the time.
• Tides and Currents: General tide and current information taken
from Coast Pilot 5 and the Fleet Guide. The mean range of tide is
1.4 ft. for Pascagoula Point, Mississippi Sound. At the mouth of
the Pascagoula River, a diurnal tide range of 1.6 ft. exists. Horn
Island experiences a tide range of 1.7 ft.
• The currents in Horn Island Pass are reported to flood N and ebbs
S averaging 1.2 knots at strength. In the dredged cut across the
bar, the ebb and flood follow the direction of the cut. Winds
greatly affect the velocity and direction of the currents, as well as
the rise and fall of the tides. It is reported that strong E winds and
seas create strong currents along the shore.

gravel, liquid sulfur, ores, and logs.
• Will receive an up-to-date traffic report prior to
setting Special Sea Detail.
14. Pilotage Requirements
• Pilotage is compulsory for all foreign vessels and all U.S.
vessels over 250 tons under register in foreign trade.
• Pilotage is optional for U.S. coast wide vessels that have

Association, 3309 Frederick Street, suite 3 Pascagoula,
MS 39567, telephone 228-762-1151.
• Pilots board vessels about 1 miles S to SE of Horn Island
Pass Lighted Whistle Buoy HI, day or night. Pilots can
be arranged for by telephone through the Mobile Marine
Operator or through ships’ agents.
• A minimum of 2 hours advance notice is requested.
15. Prominent Features
• Horn Island Pass Lighted Whistle Buoy HI, (30°08’30"N., 88°34'40"W.),
marks the approach to Horn Island Pass.
• The six refinery flares, E of Bayou Casotte, are very prominent from
offshore at night.
• At the north end of Bayou Casotte, a 140-foot gypsum pile is prominent.
• The cranes of the shipyard and the twin tanks in Pascagoula are
prominent from the sound.
• The range light towers on the W end of Petit Bois Island, the cracking
towers and tanks at the oil refinery E of Bayou Casotte, and the towers,
tanks, and elevators of the fertilizer plant on the E bank of Bayou Casotte
are also prominent.
16. Channels
• The deep water entrance is through dredged cuts in Horn
Island Pass Channel, and in Mississippi Sound for about
4 miles N of Petit Bois Island where the channel divides,
Pascagoula Channel leading about 4.5 miles NW to the
mouth of the Singing River (lower Pascagoula River),
then N about 1.5 miles to a turning basin at the railroad
bridge at Pascagoula, and Bayou Casotte Channel
leading about 4 miles N to the turning basin at the head
of Bayou Casotte.
• A Federal project provides for a depth of 44 feet in Horn
Island Pass Channel and 42 feet in the sound and in
Pascagoula and Bayou Casotte Channels to the 38-foot
Pascagoula turning basin and the 42-foot Bayou Casotte
Channel turning basin.
17. Dangers
• Shoal water up to 30 feet extends about two miles
SW of the W end of Petit Bois Island to about 0.25
miles SE of Horn Island Pass Channel Buoy 10.
• Spoil banks are on the W side of Pascagoula
Channel and on both sides of Bayou Casotte
Channel.
• Vessels should not enter the channel before the pilot
boards, especially light vessels during periods of
strong winds and adverse weather.
• In 1992, a 30-foot shoal was reported 0.4 miles SSE
of the entrance to Horn Island Pass Channel.
18. Anchorages
• Deep-draft vessels may anchor 1-2 miles S or SE of
the sea buoy, weather permitting.
• Anchorage for vessels up to 15-foot draft is available
in Mississippi Sound E of the channel.
