                TITLE 33--NAVIGATION AND NAVIGABLE WATERS
 
   CHAPTER I--COAST GUARD, DEPARTMENT OF HOMELAND SECURITY (CONTINUED)
 
PART 162--INLAND WATERWAYS NAVIGATION REGULATIONS--Table of Contents

Sec. 162.75  All waterways tributary to the Gulf of Mexico (except the 
Mississippi River, its tributaries, South and Southwest Passes and 
Atchafalaya River) 
          from St. Marks, Fla., to the Rio Grande.

    (a) The regulations in this section shall apply to:
    (1) Waterways. All navigable waters of the U.S. tributary to or 
connected by other waterways with the Gulf of Mexico between St. Marks, 
Fla., and the Rio Grande, Tex. (both inclusive), and the Gulf 
Intracoastal Waterway; except the Mississippi River, its tributaries, 
South and Southwest Passes, and the Atchafalaya River above its junction 
with the Morgan City-Port Allen Route.
    (2) Bridges, wharves, and other structures. All bridges, wharves, 
and other structures in or over these waterways.
    (3) Vessels. The term ``vessels'' as used in this section includes 
all floating craft other than rafts.
    (b) Waterways:
    (1) A clear channel shall at all times be left open to permit free 
and unobstructed navigation by all types of vessels and tows normally 
using the various waterways covered by the regulations of this section
    (2) Fairway: The District Commander may specify the width of the 
fairway required in the various waterways under his charge.
    (3) Anchoring or mooring:
    (i) Vessels or tows shall not anchor or moor in any of the land cuts 
or other narrow parts of the waterway, except in an emergency, or with 
permission of the District Commander. Whenever it becomes necessary for 
a vessel or tow to stop in any such protions of the waterway, it shall 
be securely fastened to one bank and as close to the bank as possible. 
This shall be done only at such a place and under such conditions as 
will not obstruct or prevent the passage of other vessels or tows. 
Stoppages shall be only for such periods as may be necessary.
    (ii) When tied up individually, all vessels and tows shall be moored 
by bow and stern lines. Tows shall be secured at sufficiently frequent 
intervals to insure their not being drawn away form the bank by winds, 
currents, or the suction of passing vessels. Lines shall be shortened so 
that the various barges in a tow will be as close together as possible.
    (iii) Lights shall be displayed in accordance with provisions of the 
Navigation Rules, International-Inland, Commandant Instruction M16672.2 
(series).
    (iv) Whenever any vessel or tow is moored to the bank (paragraph 
(b)(3)(i) of this section) at least one crew member shall always remain 
on board to see that proper signals are displayed and that the vessel or 
tow is properly moored at all times.
    (v) No vessel, regardless of size, shall anchor in a dredged channel 
or narrow portion of a waterway for the purpose of fishing if navigation 
is obstructed thereby.
    (4) Speed: Speeding in narrow sections is prohibited. Official signs 
indicating limited speeds shall be obeyed. Vessels shall reduce speed 
sufficiently to prevent damage when passing over vessels or structures 
in or along the waterway.
    (5) Size, assembly, and handling of tows:
    (i) On waterways 150 feet wide or less, tows which are longer than 
1,180 feet, including the towing vessel, but excluding the length of the 
hawser, or wider than one-half of the bottom width of the channel or 55 
feet, whichever is less will not be allowed, except when the District 
Commander has given special permission or the waterway has been exempted 
from these restrictions by the District Commander. Before entering any 
narrow section of the Gulf Intracoastal Waterway, tows in excess of one-
half the channel width, or 55 feet, will be required to stand by until 
tows which are less than one-half

[[Page 577]]

the channel width or 55 feet wide have cleared the channel. When passing 
is necessary in narrow channels, overwidth tows shall yield to the 
maximum. Separate permission must be received from the District 
Commander for each overlength or overwidth movement. In addition, the 
following exceptions are allowed:
    (ii) Gulf Intracoastal Waterway--Between mile 6.2 EHL (Inner Harbor 
Navigation Canal Lock) and mile 33.6 EHL tows of 78 feet in width will 
be allowed.
    (iii) Gulf Intercoastal Waterway--Between mile 33.6 EHL and the 
Mobile Bay Ship Channel, tows of 108 feet in width will be allowed if 
under 750 feet in length including the towboat but excluding the length 
of the hawser.
    (iv) Gulf Intracoastal Waterway--Mobile Bay Ship Channel to St. 
Marks, Fla., for tows made up of empty barges on the off or shallow 
side, a width of 75 feet will be allowed.
    (v) All vessels pulling tows not equipped with rudders in restricted 
channels and land cuts shall use two towlines, or a bridle on one 
towline, shortened as much as safety of the towing vessel permits, so as 
to have maximum control at all times. The various parts of a tow shall 
be securely assembled with the individual units connected by lines as 
short as practicable. In open water, the towlines and fastenings between 
barges may be lengthened so as to accommodate the wave surge. In the 
case of lengthy or cumbersome tows, or tows in restricted channels, the 
District Commander may require that tows be broken up, and may require 
the installation of a rudder or other approved steering device on the 
tow in order to avoid obstructing navigation or damaging the property of 
others. Pushing barges with towing vessel astern, towing barges with 
towing vessel alongside, or pushing and pulling barges with units of the 
tow made up both ahead and astern of the towing vessel are permissible 
provided that adequate power is employed to keep the tows under full 
control at all times. No tow shall be drawn by a vessel that has 
insufficient power or crew to permit ready maneuverability and safe 
handling.
    (vi) All tows navigating the Pass Manchac bridges in Louisiana are 
limited to no more than two barges, not to exceed a combined tow length 
of 400 feet (excluding the towboat). Vessel operators for tows exceeding 
these limits must request and receive permission from the COTP New 
Orleans prior to navigating the bridges. Requests should be made by 
telephoning the COTP at 504-589-7101. Any decision made by the COTP is 
final agency action.
    (6) Projections from vessels: Vessels or tows carrying a deck load 
which overhangs or projects over the side, or whose rigging projects 
over the side, so as to endanger passing vessels, wharves, or other 
property, shall not enter or pass through any of the narrow parts of the 
waterway without prior approval of the District Commander.
    (7) Meeting and passing: Passing vessels shall give the proper 
signals and pass in accordance with the International Rules, the 
Navigation Rules, International-Inland, Commandant Instruction M16672.2 
(Series), where applicable. At certain intersections where strong 
currents, may be encountered, sailing directions may be issued through 
navigation bulletins or signs posted on each side of the intersections.
    Note: The Corps of Engineers also has regulations dealing with this 
section in 33 CFR 207.
