COLREGs, Lookout and Buoyage
Collision-prevention duties, safe speed, lookout, risk assessment, lights and signals, IALA Region A buoyage and depth awareness.
How to prepare for a Boatmasters' Licence
Use the actual area, vessel and operation to select the route, build Annex 8 or 9 underpinning knowledge, complete the required records and training, and rehearse practical handling on the relevant vessel.
Core concepts
Concept 1
The master applies International and national collision-prevention rules appropriate to inland, harbour and limited coastal operations.
Exam cue: Identify visibility, traffic, manoeuvrability, water constraints and developing collision risk.
Concept 2
A proper lookout uses sight, hearing and available means to detect risk early and assess relative movement.
Exam cue: Determine the rule relationship before choosing a clear, timely and observable action.
Concept 3
IALA Region A lateral and cardinal marks, sound signals, lights and day shapes communicate channel and vessel status.
Exam cue: Read a mark from colour, shape, topmark, light and direction of buoyage together.
Risk pitfalls and guardrails
Treating right of way as permission to maintain an unsafe course or speed.
Guardrail: Do not treat the aggregate 601-item study allocation as an official MCA paper or assume knowledge study replaces service, records, medical fitness, safety training or practical handling.
Relying on one electronic target without a visual and situational cross-check.
Guardrail: Do not treat the aggregate 601-item study allocation as an official MCA paper or assume knowledge study replaces service, records, medical fitness, safety training or practical handling.
Confusing cardinal-mark safe-water direction with lateral channel side.
Guardrail: Do not treat the aggregate 601-item study allocation as an official MCA paper or assume knowledge study replaces service, records, medical fitness, safety training or practical handling.
Memory anchors
Lookout
Sight, hearing and all available means support early collision-risk detection.
Safe Speed
Speed must leave time and distance to assess and act effectively.
Rule then Action
Identify the encounter before choosing a bold and timely manoeuvre.
IALA A
Region A lateral marks use red to port and green to starboard in the conventional direction.
Cardinal
Black-yellow pattern, topmarks and light rhythm show the safe side of a cardinal mark.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
