Rule 19 applies to vessels not in sight of one another when navigating:
I. in an area of restricted visibility
II. near an area of restricted visibility
I only
II only
both I and II
neither I nor II
In restricted visibility, a vessel which detects by radar alone the presence of another vessel, shall determine if a close quarter situation is developing or risk of collision exists. If so, she shall:
sound the danger signal
when taking action, make only course changes
avoid altering course toward a vessel abaft the beam
all of the above
You are on a power-driven vessel in fog. Your vessel is proceeding at a safe speed when you hear a fog signal ahead of you. In this situation, the rules require you to navigate with caution until the danger of collision is over and to:
Stop your engine
Initiate a radar plot
Slow down to less than 2 knots
Reduce to bare steerageway
You are in restricted visibility and hear a fog signal forward of the beam. Nothing appears on your radar screen, the rules require you to:
Stop your engines
Sound the danger signal
Slow to bare steerageway
Sound two prolonged blasts on the whistle
While underway in fog, you hear the fog signal of another vessel ahead. If a risk of collision exists, you must:
Stop your engines and navigate with caution
Sound three short blasts and back your engines
Slow to bare steerageway and navigate with caution
Continue on your course and speed until the other vessel is sighted
Which statement concerning maneuvering in restricted visibility is false?
A vessel which hears a fog signal of the beam shall navigate with caution
A vessel which hears a fog signal forward of her beam shall stop her engine
If a vessel determines by radar that a close quarter situation is developing, she shall take
avoiding action in ample time
A vessel which cannot avoid a close quarter situation with a vessel forward of her beam
shall reduce her speed to bare steerageway
You are underway in restricted visibility you hear, about 22 degrees on the starboard bow, the fog signal of another vessel. You should:
Reduce your speed to bare steerageway
Alter course to port to pass him on her port side
Slow your engines and let her pass ahead of you
Alter the course to starboard to pass around the vessel’s stern
You are underway in thick fog. Which statement is true?
A look-out is not required if the radar is on
Fog signals are only required when a vessel is detected by radar
The engines must be stopped if a fog signal is heard forward of the beam
The radar should be kept on a short range scale for maximum detection of vessels
You hear the fog signal of another vessel forward of your beam. Risk of collision may exist. You must:
Begin a radar plot
Stop your engines
Slow down your speed
Take all way off, if necessary
In fog you observe your radar and determine that risk of collision exists with a vessel which is 2 miles off your port bow. You should:
Stop your engines
Sound the danger signal at two minute interval
Take proper avoiding action as soon as possible
Hold course and speed until the other vessel is sighted
