Introduction
The NauticEd International Sailing License and Credentials Examination
assesses a candidate's competence to skipper a sailboat for near coastal and
multiday voyages. The examination evaluates knowledge of nautical charts,
navigation, tides and currents, collision regulations, seamanship, boat
systems, weather, safety procedures, and bareboat chartering operations.
Candidates are tested on their ability to apply COLREGs, IALA buoyage
systems, and practical sailing theory to multiple-choice and scenario-based
questions. The examination emphasizes real-world decision-making, safety
awareness, and the critical thinking required to command a vessel responsibly.
A passing score demonstrates the skills and knowledge necessary for
international bareboat chartering.
,SECTION ONE: QUESTIONS 1–100
1. What is the primary purpose of a nautical chart?
A. To show only marina locations
B. To provide information about depths, hazards, aids to navigation, and
coastline
C. To predict wind speed
D. To calculate engine horsepower
RATIONALE: A nautical chart provides the essential geographic and
navigational information needed to plan and safely conduct a voyage,
including depths, hazards, aids to navigation, and coastline features.
2. What does a charted depth normally refer to when using a traditional
nautical chart?
A. Height above sea level
B. Depth relative to the chart datum
C. Maximum depth of the ocean
D. Depth measured from the masthead
RATIONALE: Charted depths are referenced to a defined chart datum,
allowing the navigator to determine the available depth when tide height is
considered.
3. A vessel is steering 090° true. In which direction is it heading?
A. North
B. South
C. East
D. West
, RATIONALE: True bearings are measured clockwise from true north; 090°
is directly east.
4. What is the difference between true north and magnetic north
called?
A. Deviation
B. Variation
C. Leeway
D. Set
RATIONALE: Variation is the angular difference between true north and
magnetic north at a given location.
5. What is a leading line used for?
A. Measuring wind speed
B. Indicating a safe course through a channel or approach
C. Determining engine temperature
D. Measuring anchor-chain length
RATIONALE: When two fixed marks line up, the resulting transit can
indicate the intended track through a navigational area.
6. What does the term "leeway" describe?
A. The sideways movement of a vessel caused by wind
B. The vessel's forward speed through water
C. The depth beneath the keel
D. The change in tide height
RATIONALE: Wind acting on the sails and hull can push a vessel sideways
from its intended heading or track.
, 7. What is "set" in navigation?
A. The speed of the current
B. The direction in which a current flows
C. The change in magnetic variation
D. The depth of the water
RATIONALE: Set is the direction toward which a current is flowing, while
drift is the speed of the current.
8. Under COLREGs Rule 12, when two sailing vessels are approaching
one another with risk of collision, which vessel is the stand-on vessel?
A. The vessel on the port tack
B. The vessel on the starboard tack
C. The vessel to windward
D. The vessel to leeward
RATIONALE: Rule 12 states that when two sailing vessels are approaching
one another with risk of collision, the vessel on the starboard tack has the
right of way.
9. A power-driven vessel is underway at night. What light configuration
should it display?
A. A single white light visible from all directions
B. Sidelights, a masthead light, and a stern light
C. Two red lights and one white light
D. A green light over a white light
RATIONALE: A power-driven vessel underway must exhibit sidelights
(red and green), a masthead light forward, and a stern light.
