Question 158

A small craft advisory forecasts winds of up to what speed?

16 kts.
24 kts.
33 kts.
48 kts.

Answer 158

33 kts. A Small Craft Advisory is issued by the National Weather Service as a warning when winds have reached dangerous speeds. Sustained wind speeds that govern the issuance of a Small Craft Advisory vary depending on geographical areas, but are generally between 20 and 33 knots. It can also be issued for other hazardous conditions such as sea and lake ice. All boaters should take appropriate precautions during a Small Craft Advisory.

The National Weather Service does not specifically identify what constitutes a “small craft”, although the United States Coast Guard informally assigns the designation to boats with a total length of less than 33 feet (10 m).

  (i) when shooting their nets: two white lights in a vertical line;
  (ii) when hauling their nets: one white light over one red light in a vertical line;
  (iii) when the net has come fast upon an obstruction: two red lights in a vertical line.

Question 166

INLAND ONLY What lights are required for a barge being pushed ahead, not being part of a composite unit?

A) Sidelights and a stern light
B) Sidelights and a special flashing light
C) Sidelights, a towing light, and a stern light
D) Sidelights, a special flashing light, and a stern light

Answer 166

B) Sidelights and a special flashing light

The vessel is being pushed ahead so the stern light on the barge is not illuminated. Inland Rules DOES require a forward-facing Special Flashing Light and sidelights on vessels pushed ahead or alongside.

• INLAND - RULE 21 - Definitions
  (g) “Special flashing light” (INLAND RULES ONLY) means a yellow light flashing at regular intervals at a frequency of 50 to 70 flashes per minute, placed as far forward and as nearly as practicable on the fore and aft centerline of the tow and showing an unbroken light over an arc of the horizon of not less than 180° nor more than 225° and so fixed as to show the light from right ahead to abeam and no more than 22.5° abaft the beam on either side of the vessel. Reminder: A Special Flashing Light applies ONLY under the Inland Rule - and the tug must display two towing lights.

Question 167

INTERNATIONAL ONLY A vessel being towed alongside shall exhibit __________.
A) one all-round white light
B) sidelights and a stern light
C) only the outboard sidelight and a stern light
D) a masthead light, sidelights, and a stern light

Answer 167

B) sidelights and a stern light

Under the International Rules, a vessel being pushed ahead displays 2 sidelights. When towed alongside, as in this question, displays sidelights and a stern light.

Under Inland Rules, the above lights would still apply with the addition of a Special Flashing Light. (Remember: a Special Flashing Light is used only under the Inland Rules. It is placed as far forward as practicable on a barge being pushed ahead or alongside.)

B) a safe water mark with a red and white vertical stripe
C) solid red buoy
D) solid green buoy

Answer 172

A) a bifurcation buoy indicating the preferred channel is to port when going shoreward

This is a junction (aka: bifurcation) buoy. They either have a red top and green bottom or visa-versa. They indicate the preferred channel to take when entering and going shoreward. Always check the chart.

When the top is colored RED, they’ll display a red light indicating the preferred channel is to port. When the top is green, it will display a green light indicating the preferred channel is to starboard.

They are very common and always flash (2+1) either in a green or red light depending on which side the preferred channel is located.

(1) Flashing 50 to 70 times per minute,
(2) Visible all around the horizon,
(3) Visible for at least 2 miles on a clear dark night,
(4) Not less than 1 and not more than 3.5 meters above the water,
(5) Approximately equally spaced, and
(6) Not more than 10 meters apart where the pipeline crosses a navigable channel. Where the pipeline does not cross a navigable channel the lights must be sufficient in number to clearly show the pipeline’s length and course.
(b) Two red lights at each end of the pipeline, including the ends in a channel where the pipeline is separated to allow vessels to pass.

Question 176

INLAND ONLY A power-driven vessel, when leaving a dock or berth, is required to sound __________.

A) four short blasts
B) one long blast
C) one prolonged blast
D) No signal is required.

Answer 176

C) one prolonged blast

Under the INLAND RULES, a vessel leaving a dock sounds one prolonged blast. This rule does not exist under the International set of Rules.

One prolonged blast is also required in BOTH sets of Rules when: 1. Approaching a bend in the channel with an intervening obstruction;
2. When underway and making way in fog.

Question 177

INLAND ONLY A vessel displaying two towing lights must _______________

A) be towing two vessels simultaneously
B) also be displaying a special flashing light next to the to towing lights
C) be pushing a vessel ahead or towing alongside
D) display the to towing lights above the stern light

Answer 177

C) be pushing a vessel ahead or towing alongside

Towing lights are yellow and have the same placement characteristics as a stern light. They’re placed on the stern of the tug and just like the sternlight have an arc of visibility of 135°.

“Yellow over Yellow = I’m a hip or forward-pushing fellow” INLAND ONLY!

Question 178

INLAND ONLY At night, you see two yellow lights in a vertical line ahead and no other lights. These lights indicate________

A) a dredge pipeline
B) a vessel towing another ahead
C) a vessel towing another alongside
D) a trawler with its nets snagged on the bottom

Answer 178

B) a vessel towing another ahead

Inland Rules require a tug that is towing by pushing ahead or towing alongside to display two yellow lights aft - called towing lights. Since the question states that you only see two yellow lights in a vertical line, you have to assume that it is a tug boat pushing a barge ahead as, if it were towing it alongside, you’d see two yellow lights in a vertical line, PLUS the sternlight of the barge on either side of the tug. By the way, if the tug is displaying two (yellow) towing lights, the barge being pushed ahead must show sidelight, and a Special Flashing Light (A yellow light placed forward on a barge being pushed ahead (or towed alongside) that flashes between 50-70 times per minute and has an arc of horizontal visibility from dead ahead through not less than 180° nor more than 225°).

Question 182

The channel that is reserved to communications regarding navigation is channel __________

13
16
22A
70

Answer 182

13

Channel 13 is the channel designated by the Bridge-to-Bridge Radiotelephone Act reserved for communications regarding navigation (Also known as the bridge-to-bridge channel.) This channel is available to all ships. Messages must be about ship navigation, for example, passing or meeting other ships. You must keep your messages short. Your power output must not be more than one watt. This is also the main working channel at most locks and drawbridges. Channel 67 is also used for Bridge-to-bridge communications in the lower Mississippi River.

Channel 16 is for hailing and distress calls and generally the channel to monitor.

22A is a Coast Guard channel used for announcements and certain communications when directed

Channel 70 is reserved exclusively for digital Selective Calling (DSC) transmissions therefore, voice communications is not allowed on this channel.

Question 184

INLAND ONLY A towing vessel pushing ahead on the Western Rivers above the Huey P. Long bridge must show __________.

A) sidelights only
B) sidelights and towing lights
C) sidelights, towing lights, and two masthead lights
D) sidelights, towing lights, and three masthead lights

Answer 184

B) sidelights and towing lights
On Western Rivers - identified as waters above the Huey P. Long Bridge, in New Orleans - vessels don’t have to display masthead lights. (This is primarily due to low bridges throughout the region).

WESTERN RIVERS ARE OTHERWISE SUBJECT TO THE INLAND RULES.

While pushing ahead, the towing vessel (tug) will display her sidelights and two towing lights in a vertical line. (Notice that she isn’t showing the two vertical white masthead lights required when when towing and not in the Western Rivers.)

The barge being pushed ahead would display a special yellow flashing light that flashes 50-70 times per minute and sidelights (no sternlight so as to not embarrass (blind) the pilot on the towing vessel).

Question 185

INTERNATIONAL ONLY A 20-meter power-driven vessel pushing ahead or towing alongside will display __________.
