Introduction
The NauticEd International Sailing License and Credentials (SLC)
examination assesses the theoretical knowledge and practical
judgment required to safely skipper a recreational sailing vessel in
international waters. Candidates must demonstrate competence in
navigation, collision avoidance, tide and current calculations,
weather interpretation, boat systems and emergency procedures. The
examination employs multiple-choice and scenario-based questions
that test real-world decision-making rather than simple recall.
Successful candidates must apply professional judgment to complex
,navigational and safety situations while adhering to international
maritime standards and charter industry expectations.
SECTION ONE: QUESTIONS 1–100
Question 1
What is the primary purpose of a nautical chart?
A. To show only marina locations and facilities
B. To provide information about depths, hazards, aids to navigation,
and coastline
C. To predict wind speed and direction
D. To calculate engine horsepower requirements
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, underwater hazards, navigational
aids, and coastal features.
Question 2
What does a charted depth normally refer to when using a
traditional nautical chart?
A. Height above mean sea level
B. Depth relative to the chart datum
C. Maximum depth of the ocean floor
D. Depth measured from the vessel's masthead
, B. Depth relative to the chart datum
RATIONALE: Charted depths are referenced to a defined chart
datum, typically the lowest astronomical tide, allowing the
navigator to determine available depth when tide height is
considered.
Question 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; 090° corresponds to directly east.
Question 4
What is the difference between true north and magnetic north
called?
A. Deviation
B. Variation
C. Leeway
D. Set
B. Variation
, RATIONALE: Magnetic variation, also called declination, is the
angular difference between true north and magnetic north, and it
varies depending on geographic location.
Question 5
What is compass deviation?
A. Error caused by local magnetic influences aboard the vessel
B. Difference between high and low tide
C. Difference between true wind and apparent wind
D. Error caused by ocean currents
A. Error caused by local magnetic influences aboard the vessel
RATIONALE: Deviation is caused by magnetic fields and ferrous
materials on or near the vessel and can vary with the vessel's
heading.
Question 6
A vessel's compass course is 090° magnetic, and magnetic variation
is 10° east. What is the approximate true course?
A. 080°
B. 090°
C. 100°
D. 110°
C. 100°
RATIONALE: With easterly variation, magnetic direction is
converted to true by adding the easterly variation: 090° + 10° = 100°.
