Question 1
Under navigation rules, a power-driven vessel less than 39.4 feet (12 meters) in length is
permitted to use a specific lighting configuration. Which of the following best describes this
allowance?
A) It may use only a red sidelight to indicate its position.
B) It may combine a masthead light and sternlight into a single all-round white light.
C) It is exempt from all lighting requirements if operating in well-lit harbors.
D) It must display two masthead lights regardless of speed.
E) It may use a flashing yellow light instead of a white sternlight.
Correct Answer: B) On power-driven vessels LESS THAN 39.4 feet in length, this light may
be used to combine a masthead light and sternlight into a single white light that can be seen
by other vessels FROM ANY DIRECTION.
Rationale: For smaller power-driven vessels (under 12 meters/39.4 feet), the law allows for
simplification of equipment. Instead of having a separate masthead light (visible 225
degrees) and a sternlight (visible 135 degrees), these two can be combined into one 360-
degree all-round white light. This ensures the vessel is visible from all angles while reducing
the number of required fixtures on a small hull.
Question 2
When is an all-round white light on a vessel under 39.4 feet used as an "anchor light"?
A) Only when the vessel is moving at speeds exceeding 5 knots.
B) When the red and green sidelights are extinguished while the vessel is at anchor.
C) During daylight hours to signal a mechanical breakdown.
D) Only when operating in international waters.
E) When the vessel is being towed by a commercial barge.
Correct Answer: B) This light serves as an anchor light when sidelights are extinguished.
Rationale: An all-round white light is multi-functional. When a vessel is underway at night,
it displays sidelights plus the white light. However, when that same vessel drops anchor, the
navigation rules require only a single all-round white light visible for 360 degrees to warn
other boaters of its stationary position. By turning off the red and green sidelights, the
operator signals to others that the boat is no longer moving or making way.
Question 3
According to Connecticut and federal law, during which timeframe must navigation lights be
displayed?
A) Only from midnight until 4:00 AM.
B) From one hour after sunset to one hour before sunrise.
C) From sunset to sunrise and during periods of restricted visibility.

D) Only when the vessel is operating in a marked channel.
E) At all times when the engine is running, regardless of the time of day.
Correct Answer: C) These lights must be displayed from sunset to sunrise and during
periods of restricted visibility, such as fog.
Rationale: Navigation lights are not just for nighttime. Their purpose is to help vessel
operators determine the position, heading, and status of other boats. Because visibility can
be compromised by environmental factors like heavy rain, snow, or thick fog during the
day, the rules mandate that lights be turned on whenever "restricted visibility" occurs to
prevent collisions.
Question 4
While boating at night, you observe a RED, a GREEN, and a WHITE light directly ahead of you.
What is your required action?
A) Maintain course and speed as you are the stand-on vessel.
B) Turn sharply to the left (port) to avoid the other vessel.
C) Give way, as you are in a head-on situation where both vessels must give way.
D) Speed up to cross the other vessel's path quickly.
E) Stop your engine and wait for the other vessel to turn first.
Correct Answer: C) GIVE WAY - you are approaching another power-driven vessel head-
on and you both must give way.
Rationale: When you see all three lights (red port side, green starboard side, and white
masthead/all-round), it means the other vessel is pointed directly at you. In a head-on
situation between two power-driven vessels, neither has the right-of-way. Both operators
are required to steer to the right (starboard) so that they pass each other "port-to-port"
(left side to left side).
Question 5
You are operating your boat at night and see only a single WHITE light on the horizon. Which of
the following scenarios are you most likely encountering?
A) You are approaching a sailing vessel from the side.
B) You are meeting a power-driven vessel head-on.
C) You are overtaking another vessel or it is anchored.
D) You are approaching a vessel engaged in commercial fishing.
E) You are seeing the port side of a large cruise ship.
Correct Answer: C) GIVE WAY - you are overtaking another vessel or it is anchored. It is
the stand-on vessel.
Rationale: A sternlight or an anchor light is white. If you see only a white light and no red
or green sidelights, you are either coming up from behind another boat (overtaking) or the
boat is stationary (anchored). In either case, the other vessel is the "stand-on" vessel. As the
, 3
"give-way" vessel, you must take early and substantial action to keep clear, though you are
permitted to pass on either side provided it is done safely.
Question 6
While underway at night, you see a GREEN light and a WHITE light off your port (left) bow.
How should you proceed?
A) Immediately turn to the right to avoid a collision.
B) Stand on, but remain alert in case the other operator fails to follow rules.
C) Give way by crossing in front of the other vessel.
D) Sound five short blasts to indicate danger.
E) Extinguish your own lights to see the other vessel better.
Correct Answer: B) STAND ON (BE PREPARED TO GIVE WAY) - you are the stand-on
vessel.
Rationale: When you see a green light, you are looking at the starboard side of another
vessel crossing from your left to your right. According to the crossing rules, the vessel that
has the other on its own port side (you) is the stand-on vessel. You should maintain your
course and speed so your movements are predictable, but you must remain vigilant in case
the other vessel (the give-way vessel) does not see you or fails to act.
Question 7
You observe a RED light and a WHITE light while boating at night. What does this tell you
about your responsibility?
A) You are the stand-on vessel and must maintain speed.
B) The other vessel is a sailboat and you have the right of way.
C) You must give way by slowing down or turning to the right to pass behind them.
D) You are in an overtaking situation and can pass on either side.
E) The other vessel is backing up and you should stop.
Correct Answer: C) GIVE WAY - you must give way to the other vessel. Slow down and
allow the vessel to pass, or you may turn to the right and pass behind the other vessel.
Rationale: Seeing a red light means you are looking at the port side of a vessel crossing
from your right to your left. Because the other vessel is in your "danger zone" (from dead
ahead to 22.5 degrees abaft your starboard beam), you are the give-way vessel. The safest
maneuver is usually to steer to the right to pass behind the other boat (stern-crossing),
rather than trying to outrun it.
Question 8
You encounter a sailing vessel at night and see only a GREEN light. What is the rule regarding
this encounter?
A) Power-driven vessels always have the right of way over sailboats.
B) You must give way, as the sailing vessel is the stand-on vessel.
