Description
Develop the practical knowledge and decision-making skills required to apply the International Regulations for Preventing Collisions at Sea (COLREGs) during real bridge-watchkeeping situations.
This advanced maritime e-learning course goes beyond simple Rule memorization. It focuses on practical recognition, collision-risk assessment, safe manoeuvring decisions and verification of results in realistic navigation scenarios.
Learners are guided through a structured operational approach:
DETECT → ASSESS → ACT → VERIFY
The course is suitable for deck officers, Officers of the Watch, deck cadets, Masters, Chief Officers and other navigation personnel who want to strengthen their practical understanding of COLREGs and improve bridge decision-making.
What You Will Learn
By completing this course, learners will strengthen their ability to:
Apply COLREG principles in practical navigation situations
Understand vessel responsibilities in common encounter scenarios
Maintain a proper lookout using all available means
Determine safe speed based on traffic, visibility and vessel maneuverability
Assess collision risk using bearings, radar, ARPA and CPA/TCPA information
Take early, substantial and readily apparent collision-avoidance action
Recognize and interpret vessel lights, day shapes and sound signals
Identify special-status vessels and understand their operational significance
Apply the correct principles in restricted visibility
Understand narrow-channel and traffic-separation considerations
Use radar, AIS and ECDIS appropriately without over-reliance
Recognize the limitations of VHF communication in collision avoidance
Apply COLREG knowledge within realistic bridge-team situations
Verify that maneuvers have produced a safe passing distance
Course Content
The course provides comprehensive coverage of the practical application of COLREGs, including:
Collision-risk assessment and avoidance action
Vessel responsibilities and encounter situations
Navigation lights, day shapes and sound signals
Restricted-visibility operations
Narrow channels and traffic separation
Radar, ARPA, AIS and ECDIS awareness
Special-status vessel recognition
Practical bridge scenarios and decision-making
Bridge-team communication
Verification of safe action
The content combines technical knowledge with practical bridge-watchkeeping examples so learners understand not only what the Rules require, but also how to apply them safely in real operating conditions.
Practical Learning Approach
The course is designed around real-world navigation and bridge decision-making.
Learners are encouraged to:
identify the situation
assess the risk
determine the applicable responsibility
select a safe response
verify the effectiveness of the action taken
Particular emphasis is placed on avoiding common watchkeeping errors such as:
delayed collision-avoidance action
over-reliance on AIS or radar
incorrect interpretation of vessel status
misuse of VHF in place of Rule-based action
failure to reassess after a manoeuvre
assuming that one vessel has an absolute “right of way”
Assessment
The course includes:
Knowledge checks throughout the training
Practical scenario-based questions
Recognition exercises
Collision-avoidance decision-making questions
A final assessment
Learners are assessed on both technical understanding and practical application of COLREG principles.

Reference Framework
The course is based on the International Regulations for Preventing Collisions at Sea (COLREGs) and is designed to support practical understanding of collision avoidance, bridge watchkeeping and vessel recognition.
Learners should always apply COLREGs together with:
good seamanship
applicable local navigation rules
Traffic Separation Scheme requirements
company procedures
vessel-specific bridge procedures
the Master’s Standing Orders
Important Note
This course is intended for professional development and knowledge enhancement.
Unless specifically stated as part of a separate approval, completion of this course does not replace statutory STCW certification, a Certificate of Competency, flag-state requirements, onboard familiarization or company-specific training.
Key Learning Philosophy
Safe navigation depends on more than knowing the Rules.
Professional watchkeeping requires the ability to:
Detect early. Assess correctly. Act decisively. Verify the result.
DETECT • ASSESS • ACT • VERIFY
Certificate Processing Time
Your e-learning certificate is available immediately after successful completion of the course and all required assessments. For STCW or flag-state-approved courses, certification can take up to 48 hours, depending on the relevant issuing authority’s verification and approval process.
