Yachtmaster Offshore Standard: Casualty Release Board

The Yachtmaster Offshore examination covers skippering, seamanship, navigation and safety awareness, but a written revision product cannot demonstrate leadership, practical equipment use or competence in a real casualty. It can teach an auditable decision structure that rejects overconfident recipes.

Build the release board in six blocks: observed casualty and consequence; people and role capacity; vessel control and exposure; containment or technical evidence; communications and outside support; next safe state. Mark facts, estimates and unknowns separately. 'Pump running' is an action; 'level falling for ten minutes' is outcome evidence.

For each current action, state a release condition and a withdrawal trigger. An emergency tiller is released only when achieved control is demonstrated. A refloat is withheld while ingress or underwater-gear damage remains unknown. A tow stops when communication, load path or safe crew position is lost. A raft is prepared early but boarding waits until the yacht is no longer the safer controlled platform or professional direction changes that decision.

Preserve reversibility and an independent check. Do not commit the only radio, battery, anchor, pump, competent helm or safe access route to one failing plan. Ask another crew member to read back the critical fact, role and trigger. When capacity or margin shrinks faster than the response improves it, move to the safer next state and escalate.
