Tiers, Levels and Operating Authority
The four BML routes, the difference between national and specified-area authority, and the conditions printed on or added to a licence.
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
Tier 1 is a national generic licence; Tier 2 is restricted to the area and operation printed on the licence.
Exam cue: Identify tier, level, water category, exact geographical limit and intended operation.
Concept 2
Level 1 addresses non-tidal or lower-scope waters, while Level 2 extends to tidal Category C and D and limited coastal operations.
Exam cue: Separate the generic authority from any endorsement or printed restriction.
Concept 3
A licence route, local requirement and specialist operation must all align before the master takes command.
Exam cue: Use the current licence and official notices rather than an employer shorthand.
Risk pitfalls and guardrails
Treating Tier 2 as a lower knowledge version of Tier 1 without recognising its specified-area design.
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.
Assuming Level 2 removes local-knowledge or operation restrictions.
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.
Using an alternative qualification without checking remaining BML conditions.
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
Tier 1

Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
