A valid Certificate of Inspection or credential (Correct answer)
A fishing log
A recreational decal only
A tide chart only

Correct answer: A valid Certificate of Inspection or credential

Inspected passenger vessels must carry a valid Certificate of Inspection or the captain's credential.

Question 3: A special sailing endorsement primarily tests knowledge of what additional skill area?

Radar navigation only
Reading wind and handling sails (Correct answer)
Engine oil changes
Fuel injection systems

Correct answer: Reading wind and handling sails

A sailing endorsement focuses on wind awareness, points of sail, and sail handling.

Question 4: What is the purpose of a Personal Locator Beacon (PLB)?

A light beacon to mark your boat's location at night
A personal distress device that transmits your GPS location to search and rescue satellites when activated (Correct answer)
To track vessel speed and distance traveled
A beacon that automatically calls the nearest marina

Correct answer: A personal distress device that transmits your GPS location to search and rescue satellites when activated

A PLB is a personal emergency device that, when activated, sends a distress signal with GPS coordinates to SAR satellites.

Question 5: A sudden drop in temperature combined with a wind shift while boating most likely means what?

The weather is stabilizing
You are approaching warmer water
A cold front or weather change is passing through (Correct answer)
Fog will clear immediately

Correct answer: A cold front or weather change is passing through

A temperature drop with a wind shift often marks the passage of a front and changing conditions.

Question 6: What should you do if your boat capsizes in open water?

Stay with the boat — it provides flotation and is easier for rescuers to spot than a person in the water (Correct answer)
Dive underwater to find your belongings
Remove your life jacket to swim more easily
Swim toward the nearest shore immediately

Correct answer: Stay with the boat — it provides flotation and is easier for rescuers to spot than a person in the water

Stay with the capsized vessel as it provides flotation support, is much more visible to rescuers than a person in the water, and conserves energy compared to swimming long distances.

Question 7: What light configuration does an anchored vessel display at night?

A flashing yellow light
No lights are required at anchor
A white all-around light visible 360 degrees (Correct answer)
Red and green sidelights only

Correct answer: A white all-around light visible 360 degrees

Question 9: Under what circumstances can you legally discharge waste from a Type I or Type II marine sanitation device (MSD)?

Only in designated pump-out stations
Only when more than 3 miles from shore on coastal waters (Correct answer)
Never — all MSDs are illegal
Anywhere on all US waterways

Correct answer: Only when more than 3 miles from shore on coastal waters

Type I and II MSDs treat waste before discharge and may be used beyond 3 miles from shore on coastal waters; inland waterways may have stricter no-discharge zones.

Question 10: Why should you use marine-grade fuel and check for ethanol content?

Ethanol can absorb water and damage marine fuel systems (Correct answer)
It makes the boat float higher
It increases the horn volume
It reduces the need for life jackets

Correct answer: Ethanol can absorb water and damage marine fuel systems

Ethanol attracts water and can degrade fuel lines and components in marine engines.

Question 11: What is a Type IV throwable PFD and when must it be aboard?

A PFD worn only by the captain

Question 19: For a personal watercraft endorsement, operators learn that steering control is usually lost when they do what?

Release the throttle completely (Correct answer)
Wear a life jacket
Apply more throttle
Lean into a turn

Correct answer: Release the throttle completely

Most PWCs steer only under thrust, so releasing the throttle can eliminate steering control.

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

Both should stop and wait
Both vessels should alter course to starboard (right) so they pass port-to-port (Correct answer)
The faster vessel should speed up to pass first
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: In a crossing situation between two power-driven vessels, which vessel is the give-way vessel?

The vessel that has the other on its own starboard side (Correct answer)
The vessel that has the other on its own port side
The larger vessel
The faster vessel

Correct answer: The vessel that has the other on its own starboard side

The vessel that sees the other on its starboard side must give way and keep clear.

Question 22: Which PFD type is designed for calm inland water where rescue is quick and the wearer is conscious?

Type V — Special Use Device
Type III — Flotation Aid (Correct answer)
Type II — Near-Shore Buoyant Vest
Type I — Offshore Life Jacket

Correct answer: Type III — Flotation Aid

Type III flotation aids are comfortable for active water sports in calm water where fast rescue is likely and the person can stay face-up on their own.

Question 23: What is the primary danger of lightning while you are boating on open water?

It attracts fish to the surface
Your boat may be the tallest object and attract a strike (Correct answer)
It cools the water dangerously
It improves radio reception

Correct answer: Your boat may be the tallest object and attract a strike

On open water a boat is often the highest point, making it more likely to be struck by lightning.

Question 24: What color is the port (left) side navigation light on a vessel?

Red (Correct answer)
White
Yellow
Green

Correct answer: Red

The port side navigation light is red, visible from dead ahead to 112.5 degrees on the left side.

Question 25: What is the proper way to fit a life jacket?

It should fit snugly without riding up above the chin when lifted at the shoulders (Correct answer)
It only needs to be zipped halfway for easy removal
Size does not matter as long as it can be worn
It should hang loosely for comfort

Correct answer: It should fit snugly without riding up above the chin when lifted at the shoulders

A properly fitting PFD should be snug and, when you lift the shoulder straps, should not rise above the chin or ears — a loose PFD may slip off in the water.

Question 26: What does a masthead light on a power-driven vessel look like and what arc does it cover?

A green light covering 360 degrees
A red light covering 225 degrees forward
A yellow flashing light covering 112.5 degrees
A white light covering 225 degrees from ahead to each side (Correct answer)

The masthead light is a white light covering 225 degrees from dead ahead to 22.5 degrees abaft the beam on each side.

Question 27: A vessel ringing a bell rapidly for 5 seconds in fog or restricted visibility is signaling what?

The vessel is in distress
The vessel is anchored and warning of its position (Correct answer)
The vessel is underway
The vessel is requesting a pilot

Correct answer: The vessel is anchored and warning of its position

An anchored vessel rings its bell rapidly for 5 seconds every minute to warn nearby vessels of its position in restricted visibility.

Question 28: What does a red navigational buoy (nun buoy) indicate when returning from sea?

Mark the right (starboard) side of the channel — pass to the right when returning to port (Correct answer)
Indicate a no-wake zone
Mark a swimming area
Mark the left side of the channel

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 29: What is the 'HELP' position used for in cold water survival?

Signaling rescuers from the water
Heat Escape Lessening Posture — curling up to retain body heat (Correct answer)
Helping an injured passenger float
A swimming technique to move faster

Correct answer: Heat Escape Lessening Posture — curling up to retain body heat

HELP (Heat Escape Lessening Posture) involves curling knees to the chest to slow heat loss and reduce hypothermia risk.

Question 30: How often should you inspect steering and throttle cables?

Only once when the boat is new
Only after selling the boat
Regularly, checking for corrosion, stiffness, or fraying (Correct answer)
Never, they are maintenance-free

Correct answer: Regularly, checking for corrosion, stiffness, or fraying

Routine inspection of control cables prevents dangerous steering or throttle failure while underway.

Question 31: What is the safest speed to travel in a crowded or congested waterway?

Whatever speed feels comfortable
A slow, no-wake speed (Correct answer)
Full throttle to clear the area quickly
The posted highway speed limit

Correct answer: A slow, no-wake speed

Slow, no-wake speed reduces the risk of collision and damage from your wake in crowded areas.

Question 32: What causes cavitation on a boat propeller?

Air bubbles or ventilation disrupting water flow around the blades (Correct answer)
A dead battery
Too much fuel
An overloaded cooler

Correct answer: Air bubbles or ventilation disrupting water flow around the blades

Cavitation happens when vapor bubbles form and collapse around the prop, reducing thrust and damaging blades.

Question 33: How should throwable PFDs (Type IV) be stored on a boat?

Mounted on the transom only
In an immediately accessible location that can be grabbed and deployed quickly (Correct answer)
Locked in a storage compartment below deck
Attached to the anchor line

Correct answer: In an immediately accessible location that can be grabbed and deployed quickly

Type IV throwable devices must be immediately accessible — never stored under hatches or locked away because seconds matter in a rescue.

Question 34: A white regulatory buoy with an orange circle displays what type of marking?

Safe water
A danger warning
General information
A controlled area such as a speed or no-wake zone (Correct answer)

Correct answer: A controlled area such as a speed or no-wake zone

An orange circle indicates a controlled area, often with restrictions like speed limits printed inside.

Question 35: What is carbon monoxide poisoning risk highest near on a boat?

The steering wheel
The anchor locker
The exhaust outlets and swim platform (Correct answer)
The bow rail

Correct answer: The exhaust outlets and swim platform

Carbon monoxide accumulates near engine exhaust, making swim platforms and rear areas most dangerous.

Question 36: A buoy showing an orange square with a boat symbol crossed out means what?

It marks safe anchorage
Boats are excluded from that area (Correct answer)
It marks a fishing zone
It is a fuel dock

Correct answer: Boats are excluded from that area

An orange crossed-out symbol marks an exclusion area closed to boating.

Question 37: What action do you take if you are overtaking another vessel?

Pass on the starboard side
Keep well clear of the way of the vessel you are overtaking (Correct answer)
Pass on the port side
Wait till the vessel slows down

Correct answer: Keep well clear of the way of the vessel you are overtaking

When overtaking another vessel, the International Regulations for Preventing Collisions at Sea (COLREGs) designate the overtaking vessel as the 'give-way' vessel. This means you are responsible for keeping well clear of the vessel you are passing, ensuring you do not impede its course or speed. Maintaining a safe distance and clear passage is paramount to prevent collisions.

Question 38: What is required when transferring ownership of a registered boat in the US?

A signed title transfer and re-registration with the state by the new owner (Correct answer)
Notifying the Coast Guard only
Simply updating the registration sticker
Only a verbal agreement between buyer and seller

Correct answer: A signed title transfer and re-registration with the state by the new owner

When a boat is sold, the title must be signed over to the new owner, who must then register the vessel with the state.

Question 39: What does a 'no wake zone' sign require boat operators to do?

Stop the engine completely
Anchor their vessel until the zone is cleared
Maintain the slowest speed necessary to maintain steering (Correct answer)
Reduce speed to exactly 5 mph

Correct answer: Maintain the slowest speed necessary to maintain steering

In a no-wake zone, operators must reduce speed to the minimum needed to maintain steerage, producing no wake that could damage property or endanger others.

Question 40: What does a single prolonged blast on a horn signal?

Passing on the port side
Anchoring in a channel
Warning signal used when leaving a dock, approaching a blind bend, or in reduced visibility (Correct answer)
Distress signal requesting immediate assistance

Correct answer: Warning signal used when leaving a dock, approaching a blind bend, or in reduced visibility

One prolonged blast (4-6 seconds) serves as a warning signal when departing a dock, approaching a blind curve, or operating in fog/reduced visibility to alert other vessels of your presence.

Question 41: How long is a typical US state boat registration valid before it must be renewed?

5 years
1 year
6 months
3 years (Correct answer)

Correct answer: 3 years

Most US states issue boat registrations valid for three years, though periods vary by state.

Question 42: Before a long trip, checking the bilge pump ensures:

The radio has more range
The engine runs faster
The anchor holds better
Water can be removed if it enters the hull (Correct answer)

Safety instruction and required equipment (Correct answer)
Free fuel for a week
A commercial license
A fishing permit

Correct answer: Safety instruction and required equipment

Rental operators must give safety instruction and supply required safety equipment.

Question 45: A special sailing craft endorsement teaches that a sailboat under sail alone is generally considered what in navigation rules?

Exempt from all rules
A vessel with limited maneuverability compared to power vessels (Correct answer)
Always the give-way vessel
A commercial vessel

Correct answer: A vessel with limited maneuverability compared to power vessels

Under sail, a sailboat often has right of way over power vessels because it is less maneuverable.

Question 46: What does five or more short blasts on a horn indicate?

The vessel is requesting a bridge opening
The vessel is departing a dock
A danger or distress signal — the other vessel's intentions are unclear (Correct answer)
The vessel is anchoring

Correct answer: A danger or distress signal — the other vessel's intentions are unclear

Five or more short rapid blasts is the danger signal, used when the operator is in doubt about the intentions of another vessel.

Question 47: What should you do with the drain plug before launching a boat?

Install and secure it so water doesn't enter the hull (Correct answer)
Remove it to let air out
Replace it with a life jacket
Leave it in the truck
