Boating Certification Test Navigation Rules 3 — Questions and Answers
Question 1: What does a vessel display when it is anchored at night?
- A red light all around
- An all-round white light (Correct answer)
- A red and green sidelight
- No lights are required
Correct answer: An all-round white light
An anchored vessel displays an all-round white light visible from 2 miles.
Question 2: What action should a power-driven vessel take when it is the stand-on vessel in a crossing situation?
- Immediately slow down and stop
- Maintain course and speed, but be ready to take action if necessary (Correct answer)
- Turn sharply to port
- Sound five short blasts and stop
Correct answer: Maintain course and speed, but be ready to take action if necessary
The stand-on vessel must maintain course and speed but must act if collision becomes inevitable.
Question 3: At what range must a vessel's masthead light be visible?
- 1 nautical mile
- 3 nautical miles (Correct answer)
- 2 nautical miles
- 5 nautical miles
Correct answer: 3 nautical miles
A masthead light on a power-driven vessel 50 meters or more in length must be visible at 6 miles; for smaller vessels it varies, but 3 miles is the standard for vessels 12–50 meters.
Question 4: A vessel engaged in towing with a tow exceeding 200 meters astern displays what lights at the masthead?
- Two masthead lights in a vertical line
- Three masthead lights in a vertical line (Correct answer)
- One masthead light plus a towing light
- One masthead light only
Correct answer: Three masthead lights in a vertical line
Three masthead lights in a vertical line indicate a towing vessel whose tow exceeds 200 meters.
Question 5: Which situation describes a head-on meeting scenario?
- Vessels approaching at right angles
- Vessels approaching end-on or nearly so (Correct answer)
- One vessel overtaking another from astern
- A vessel entering a narrow channel
Correct answer: Vessels approaching end-on or nearly so
A head-on situation exists when vessels are approaching end-on or nearly end-on so both see each other's masthead lights in line.
Question 6: What lights must a vessel under oars display at night?
- A white stern light only
- A flashlight or lantern showing a white light (Correct answer)
- Red and green sidelights
- An all-round white light and stern light
Correct answer: A flashlight or lantern showing a white light
A vessel under oars may display the lights of a sailing vessel but must at minimum show a flashlight or lantern with a white light.
Question 7: What does the term 'safe speed' require of a vessel operator?
- Never exceeding 5 knots in any conditions
- Setting a speed that allows proper action to avoid collision within an appropriate distance (Correct answer)
- Matching the speed of nearby traffic
- Reducing to bare steerageway whenever another vessel is visible
Correct answer: Setting a speed that allows proper action to avoid collision within an appropriate distance
Safe speed allows the vessel to stop or maneuver effectively within the distance required by prevailing conditions.
