Introduction
The NauticEd International Sailing License and Credentials (SLC)
Examination assesses a candidate's competence to safely skipper and
charter a sailboat in near-coastal and international waters. The
exam evaluates knowledge of navigation, COLREGs, weather, boat
systems, anchoring, docking, and emergency procedures. Candidates
must demonstrate the practical and theoretical skills required for
bareboat chartering, including Mediterranean mooring, tidal
calculations, and crew leadership. The examination combines
multiple-choice questions with on-the-water assessments,
emphasizing real-world decision-making, regulatory compliance, and
maritime safety.
,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
B. To provide information about depths, hazards, aids to
navigation, and coastline
RATIONALE: A nautical chart provides the essential geographic
and navigational information needed to plan and safely conduct a
voyage, including water depths, navigational hazards, aids to
navigation, and coastal 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
B. Depth relative to the chart datum
, RATIONALE: Charted depths are referenced to a defined chart
datum, allowing the navigator to determine the available depth
when tide height is considered. This ensures safe passage planning.
3. A vessel is steering 090° true. In which direction is it
heading?
A. North
B. South
C. East
D. West
C. East
RATIONALE: True bearings are measured clockwise from true
north. A bearing of 090° corresponds to due east.
4. What is the difference between true north and magnetic
north called?
A. Deviation
B. Variation
C. Leeway
D. Set
B. Variation
, RATIONALE: Variation is the angular difference between true
north and magnetic north at a given location. It changes with
geographic position and must be applied when converting between
true and magnetic bearings.
5. 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
A. The sideways movement of a vessel caused by wind
RATIONALE: Wind acting on the sails and hull can push a
vessel sideways from its intended heading or track. This is called
leeway and must be accounted for in navigation.
6. What is "set" in navigation?
A. The speed of the current
B. The direction toward which the current is flowing
C. The vessel's compass error
D. The rate of tidal change
B. The direction toward which the current is flowing
