- Persistent vibration through the hull while underway at normal speed (Correct answer)
- Fuel consumption increase of 5%
- Engine runs roughly at high RPM
- Compass deviation of more than 3 degrees
Correct answer: Persistent vibration through the hull while underway at normal speed
Persistent vibration through the hull while underway often indicates propeller damage, shaft misalignment, or damaged struts — conditions that require haul-out for inspection.
Question 17: When meeting a vessel in a crossing situation, the give-way vessel should preferably:
- Speed up to cross ahead of the stand-on vessel
- Sound one blast and maintain course
- Slow down and let the stand-on vessel pass ahead
- Alter course to pass astern of the stand-on vessel (Correct answer)
Correct answer: Alter course to pass astern of the stand-on vessel
Give-way vessels should take positive action, ideally altering course to pass astern of the stand-on vessel, avoiding crossing ahead.
Question 18: What action must a give-way vessel take in a crossing situation?
- Wait for the stand-on vessel to maneuver
- Sound three short blasts and stop
- Take early and substantial action to keep well clear (Correct answer)
- Speed up to cross ahead
Correct answer: Take early and substantial action to keep well clear
The give-way vessel must take early, large, and obvious action to avoid the stand-on vessel, preferably altering course to pass astern.
Question 19: What is a squall, and why should mariners be concerned about one?
- A gradual increase in wind over several hours preceding a cold front
- A sudden, brief but intense burst of wind often accompanied by rain or hail (Correct answer)
- A persistent area of calm found near the equator
- A localized area of dense fog near shore
Correct answer: A sudden, brief but intense burst of wind often accompanied by rain or hail
A squall is a sudden, sharp increase in wind speed lasting minutes, often accompanied by precipitation, and can cause dangerous sea conditions with little warning.
Question 20: What is the polite way to set anchor when you are unsure your hook is holding?
- Leave and hope for the best
- Back down to test the set and monitor your position (Correct answer)
- Anchor closer to others as backup
- Tie to another boat's anchor line
Correct answer: Back down to test the set and monitor your position
Testing your set and watching for drag protects you and surrounding vessels from collisions.
Question 21: What is a 'line of position' (LOP) used for in celestial or coastal navigation?
- Establishing one component of a vessel's fix (Correct answer)
- Identifying a vessel's home port
- Recording fuel tank capacity
- Marking a shipping lane boundary
Correct answer: Establishing one component of a vessel's fix
A line of position (LOP) is a bearing, range, or other measurement along which the vessel must lie, and two or more LOPs crossed produce a fix.
Question 22: What hazard does carbon monoxide present aboard a vessel?
- It is an odorless, toxic gas from engine exhaust that can cause poisoning (Correct answer)
- It improves engine efficiency
- It only affects electronics
- It is harmless in open air
Correct answer: It is an odorless, toxic gas from engine exhaust that can cause poisoning
Carbon monoxide from exhaust is colorless and odorless and can accumulate to lethal levels in cabins and around the stern.

- Only US-built, US-flagged, US-owned, and US-crewed vessels may carry cargo between US ports (Correct answer)
- Foreign vessels may carry cargo only with a USCG permit
- Foreign vessels must pay a higher tariff
Correct answer: Only US-built, US-flagged, US-owned, and US-crewed vessels may carry cargo between US ports
The Jones Act (Merchant Marine Act of 1920) requires cargo shipped between US ports to be carried on vessels that are US-built, US-flagged, US-owned, and crewed by US citizens.
Question 25: According to COLREGS, which vessel is the 'stand-on' vessel in a crossing situation?
- The larger vessel
- The vessel with the other on its starboard side (Correct answer)
- The faster vessel
- The vessel with the other on its port side
Correct answer: The vessel with the other on its starboard side
In a crossing situation, the vessel that has the other on its starboard side is the stand-on vessel and must maintain course and speed.
Question 26: What is the purpose of a Certificate of Inspection (COI) issued by the USCG?
- Verifies the vessel's documentation number
- Approves a vessel to enter foreign ports
- Certifies that an inspector has reviewed safety equipment
- Certifies that an inspected vessel meets USCG standards for its route, trade, and passenger/cargo capacity (Correct answer)

A COI issued to inspected USCG vessels certifies they meet federal safety standards for their specific route, trade, and authorized number of passengers and crew.
Question 27: What does MARPOL Annex V regulate?
- Sewage treatment aboard vessels
- Air emissions from vessel engines
- Oil discharge from vessels
- Garbage disposal from ships (Correct answer)
Correct answer: Garbage disposal from ships
MARPOL Annex V governs the disposal of garbage from ships, prohibiting overboard disposal of most waste and regulating what may be discharged and where.
Question 28: What is a compass rose on a nautical chart used for?
- Determining water depth
- Identifying shipping lanes
- Reading true and magnetic bearings (Correct answer)
- Measuring distances
Correct answer: Reading true and magnetic bearings
A compass rose shows both true north (outer ring) and magnetic north (inner ring) so mariners can convert between the two for navigation.
Question 29: What should you do first when fire breaks out in the engine compartment?
- Jump overboard immediately
- Open the hatch and use a fire extinguisher directly
- Call the marina on VHF
- Shut off the fuel supply and discharge the engine compartment extinguisher without opening the hatch (Correct answer)
Correct answer: Shut off the fuel supply and discharge the engine compartment extinguisher without opening the hatch
Shut off fuel immediately and discharge a fixed or handheld extinguisher through the access port — opening the hatch feeds oxygen and can cause flashover.
