Maritime Safety and Navigation Law
What this domain tests
This domain combines 선박안전법, 해사안전법, and the 국제해상충돌예방규칙 (COLREG). Expect questions on ship inspection, safety management, navigation conduct, lights and shapes, and collision avoidance.
Core rules
- 선박안전법 governs ship inspections, safety certificates, and technical standards. Inspections include periodic, intermediate, and temporary categories; classification societies may perform delegated work.
- 해사안전법 covers navigation safety, safety management systems, traffic control, and duties after collision or distress.
- COLREG requires lookout, safe speed, and risk assessment. Steering rules include head-on (both alter to starboard), crossing (give-way vessel avoids crossing ahead), and overtaking (overtaking vessel keeps clear).
- Narrow channels and traffic separation schemes impose special duties.
Worked example
Two power-driven vessels are crossing. Vessel A sees Vessel B on its starboard side. A is the give-way vessel under Rule 15. A must take early and substantial action to keep clear; it should normally pass astern of B. B, the stand-on vessel, keeps course and speed but must act if collision is imminent. Reasoning: the side on which the other vessel appears determines the give-way burden, not size or speed.
Traps
Do not apply road-traffic intuition. Overtaking is defined by approaching from more than 22.5° abaft the beam, not by relative speed alone. Do not ignore restricted visibility or narrow-channel rules. Light arcs and sound signals are frequently tested.
Key points
- Inspections and certificates belong to 선박안전법.
- COLREG crossing: give way to the vessel on your starboard side.
- Overtaking vessel keeps clear.
- Stand-on vessel must still act if risk becomes imminent.
- Safe speed depends on visibility, traffic, and maneuverability.
