BML Revision: Vessel Handling in Extreme Weather (Section 4)

Revision card 8 of 16 — Boatmaster's Licence, Tier 1 Level 2 Underpinning Knowledge, MSN 1853 Annex 10. Note: in the source document this content sits inside the Emergency Manoeuvres part of Section 3 rather than under its own heading, but the syllabus contents page still lists it as its own topic area — the coverage is the same either way.

Carried Over From Level 1

• Precautions and procedures for heavy weather: rigging safety lines, restricting access to the weather deck, securing loose items
• How to assess a place of safety
• How to turn a vessel safely in rough seas

New for Level 2

• Hazards resulting from pitching, pounding, rolling, racing and broaching-to (turning side-on to the sea, or taking a following sea over the stern in surf)
• How and when to make a report on the vessel's condition of seaworthiness

Quick Self-Check

• What's broaching-to, and why is it dangerous?
• When, and to whom, would you report a concern about your vessel's seaworthiness?
