NAUTICED INTERNATIONAL SAILING
LICENSE AND CREDENTIALS (SLC) EXAM
QUESTIONS WITH ANSWERS | UPDATED
Core Domains
1. Nautical Charts and Navigation Plotting
2. Tides, Currents, and Tidal Calculations
3. Collision Regulations (COLREGs) and Rules of the Road
4. Weather and Sea Conditions
5. Boat Systems, Rigging, and Sails
6. Anchoring, Mooring, and Docking Procedures
7. Safety, Emergency Procedures, and Communications
8. Electronic Navigation and Instruments
Introduction
This comprehensive examination assesses the knowledge and practical
competency of candidates seeking the NauticEd International Sailing License
and Credentials (SLC). The assessment evaluates understanding of coastal
navigation, chart plotting, tidal calculations, collision prevention, weather
interpretation, boat systems, and emergency procedures. Multiple-choice and
scenario-based questions emphasize real-world application, critical thinking,
and safe decision-making essential for international bareboat chartering.
Content aligns with the NauticEd Bareboat Charter Master curriculum and the
100-question SLC theory test blueprint, ensuring rigorous preparation for
professional sailing certification.
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 essential geographic and
navigational information needed to plan and safely conduct a voyage,
including water depths, 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,
typically the lowest astronomical tide, allowing the navigator to determine
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
, C. East
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. Variation
B. Deviation
C. Declination
D. Set
A. Variation
RATIONALE: Variation is the angular difference between true north and
magnetic north, which changes depending on geographic location and is
shown on charts.
5. What does the term "set" refer to in navigation?
A. The direction toward which the current is flowing
B. The speed of the current
C. The vessel's heading
D. The wind direction
A. The direction toward which the current is flowing
RATIONALE: Set is the direction toward which the current is flowing,
expressed in degrees true.
6. What does the term "drift" refer to in navigation?
A. The direction of the current
B. The speed of the current
, C. The sideways movement caused by wind
D. Water depth
B. The speed of the current
RATIONALE: Drift is the speed of the current, typically expressed in
knots.
7. What is "Course Over Ground" (COG)?
A. The direction the vessel is pointing
B. The actual direction the vessel moves relative to the earth's surface
C. The compass heading
D. The wind direction
B. The actual direction the vessel moves relative to the earth's surface
RATIONALE: COG accounts for the effects of current and leeway and is
distinct from the vessel's heading, which is the direction the bow points.
8. What is "Speed Over Ground" (SOG)?
A. The speed through the water
B. The actual speed over the earth's surface
C. The wind speed
D. The current speed
B. The actual speed over the earth's surface
RATIONALE: SOG is measured by GPS and accounts for current and
leeway, representing the vessel's actual speed over the earth's surface.
9. What is the Rule of Twelves used for?
A. Calculating tidal height at any given time between high and low tide
B. Determining wind speed
