NASBLA Boating Safety Certification Test — Questions and Answers

Question 1: Why is carbon monoxide a particular hazard on boats?

Boats don't produce carbon monoxide
It only occurs when the boat is at dock
Carbon monoxide only affects cars, not boats
Engine exhaust can accumulate in enclosed spaces and near swim platforms, causing poisoning without warning (Correct answer)

Correct answer: Engine exhaust can accumulate in enclosed spaces and near swim platforms, causing poisoning without warning

Boat engines, generators, and cooking equipment produce CO that can accumulate in cabins, under canvas covers, and near swim platforms (exhaust stations). CO is odorless and can quickly reach lethal levels.

Question 2: What is a 'float plan' and why is it important?

An insurance form for water emergencies
A map showing floating hazards on your route
A document required by law to be filed with the Coast Guard
A written document left with a trusted person detailing your trip itinerary and vessel description (Correct answer)

Correct answer: A written document left with a trusted person detailing your trip itinerary and vessel description

A float plan left with a trusted person allows rescuers to know where to search if you fail to return on schedule.

Question 3: What does one prolonged blast every two minutes indicate in restricted visibility?

A vessel at anchor
A sailing vessel
A power-driven vessel underway making way (Correct answer)
A vessel aground

Correct answer: A power-driven vessel underway making way

A power-driven vessel making way in fog sounds one prolonged blast at intervals of not more than two minutes.

Question 4: Which of the following is the best practice for protecting the aquatic environment when fueling your boat?

Fuel while the engine is running
Avoid spills and never let fuel overflow into the water (Correct answer)
Overfill the tank to avoid a second stop
Dump excess fuel overboard

Correct answer: Avoid spills and never let fuel overflow into the water

Preventing fuel spills protects water quality and wildlife, so fuel carefully and avoid overflow.

Question 5: What should you do if you run aground?

Gun the engine to power through
Wait for another boat to tow you off at full speed
Stop the engine immediately, check for hull damage and leaks, attempt to free the boat at the next high tide or by shifting weight (Correct answer)
Abandon the boat immediately

Correct answer: Stop the engine immediately, check for hull damage and leaks, attempt to free the boat at the next high tide or by shifting weight

When grounded: stop the engine to prevent intake damage, check for hull damage and flooding, attempt to shift weight to free the vessel, wait for rising tide if applicable, or call for professional assistance.

Question 6: What navigation lights must a vessel under 23 feet (7 meters) display while underway at night?

Only a flashlight may be used
No lights required for small vessels
Combined red/green bow light and a white stern light, or an all-around white light (Correct answer)

Correct answer: Combined red/green bow light and a white stern light, or an all-around white light

Vessels under 7 meters may display sidelights and a stern light or, if not practical, an all-around white light.

Question 7: How does hypothermia develop in cold water and what are the stages?

It takes several hours to develop in any water temperature
Hypothermia only occurs in freezing water
Cold water only causes discomfort
Body loses heat 25x faster in water than air; stages progress from shivering to confusion to unconsciousness to cardiac arrest (Correct answer)

Correct answer: Body loses heat 25x faster in water than air; stages progress from shivering to confusion to unconsciousness to cardiac arrest

Water conducts heat 25x faster than air. Hypothermia progresses through stages: shivering and impaired judgment, loss of motor control, confusion and drowsiness, loss of consciousness, and eventually cardiac arrest.

Question 8: If you see only a green light from another vessel at night, what does this indicate?

The vessel is anchored
The vessel is a sailing vessel under sail only
The vessel is operating in reverse
You are seeing the vessel's starboard side — it is crossing your path from right to left (Correct answer)

Mark a swimming area
Mark the right (starboard) side of the channel — pass to the right when returning to port (Correct answer)

Correct answer: Mark the right (starboard) side of the channel — pass to the right when returning to port

Red nun buoys mark the right (starboard) side of the channel when returning from open water (Red Right Returning). Keep red markers on your right when heading upstream or returning to port.

Question 13: What does a single all-round white light on an anchored boat at night indicate?

The vessel is underway at high speed
The vessel is a police boat
The vessel is towing
The vessel is at anchor (Correct answer)

Correct answer: The vessel is at anchor

An anchored vessel displays an all-round white light so others can see it at night.

Question 14: What sound signal indicates a vessel intends to pass you on its port side (one short blast)?

Three short blasts
One short blast (Correct answer)
Five short blasts
Two short blasts

Correct answer: One short blast

One short blast signals an intent to alter course to starboard, passing port to port.

Question 15: What action helps prevent the spread of aquatic invasive species when moving your boat between lakes?

Skip cleaning if the water looked clean
Leave the boat wet between trips
Transfer bait water between lakes
Clean, drain, and dry the boat and equipment (Correct answer)

A standard bathroom mirror — effective up to 1 mile

Correct answer: A retroreflective mirror — can signal rescuers up to 10 miles away in bright sunlight

A signal mirror can flash sunlight visible up to 10 miles or more to aircraft and vessels, making it an effective non-pyrotechnic distress signal.

Question 20: In a head-on meeting situation between two power vessels, what should each vessel do?

The faster vessel should speed up to pass first
Both vessels should alter course to starboard (right) so they pass port-to-port (Correct answer)
Both should stop and wait
The larger vessel has right of way

Correct answer: Both vessels should alter course to starboard (right) so they pass port-to-port

When two power vessels are meeting head-on, both should alter course to starboard (right), passing each other port side to port side, the same principle as vehicles passing on a road.

Question 21: What sound signal is used when a power vessel backs away from a dock?

Four short blasts
One short blast
Three short blasts (Correct answer)
Two short blasts

Correct answer: Three short blasts

Three short blasts indicate that the vessel's engine is operating in reverse.
