Mooring, Unmooring and Line Plans
Preparation, line selection, safe stations, winches and windlasses, berthing, letting go, warping and monitoring alongside.
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
A line plan balances wind, stream, berth geometry, vessel movement and the sequence in which restraint is applied or released.
Exam cue: Brief line names, leads, sequence, communications and safe positions.
Concept 2
Snap-back, bights, machinery, leads, propellers and thrusters create critical line-handling hazards.
Exam cue: Keep people out of bights and foreseeable snap-back zones.
Concept 3
Moorings must be tended as water level, loading, weather and passing traffic change.
Exam cue: Use propulsion and lines together without loading equipment beyond its safe working limits.
Risk pitfalls and guardrails
Heaving on a poorly led line or with crew inside the bight.
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.
Letting go before confirming engines, steering, traffic and remaining line control.
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.
Leaving moorings unattended through a major level or loading change.
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
Line Plan
Head, stern, breast and spring lines control different vessel movements.
Bight Danger
Never stand in a bight or the likely path of a failed line.
Lead Clear
Keep lines clear of propellers, thrusters, sharp edges and unsafe angles.
Closed Loop
The bridge and mooring stations confirm every critical instruction.
Tend Lines
Adjust moorings as tide, draught, weather and traffic change.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
