Module 18 - Signals & Communications
Yachtmaster Offshore Standard: Signals
What you will learn
Integrate communication priority, procedure, crew roles, vessel control and independent fallback into one defensible Yachtmaster command answer.
Signals knowledge becomes command performance only when the skipper can communicate without losing the vessel, the emergency task or the crew's shared picture.
At Yachtmaster level, communications are part of command rather than a separate recital. The skipper must choose the correct priority and procedure while preserving vessel control, lookout, navigation, damage control and a reliable crew picture.
A defensible answer says what is known, which communication path is available, who owns the helm, radio, position and emergency action, and what measurable change triggers escalation or a different path. It does not assume that pressing DSC, making a perfect call or carrying a charged handheld proves that help has been reached.
The practical examination includes signals and safety awareness within an assessment of real skippering and seamanship. This lesson can rehearse the decision structure and language, but it cannot demonstrate radio-operating fluency, practical command or examination competence.
Worked example
A dismasting injures one crew member, removes the masthead antenna and leaves the yacht manoeuvrable under engine with clear sea room.
- 1Put one person on vessel control and lookout, one on casualty care and one on position and communications; combine roles explicitly if the crew is smaller.
- 2Assess urgency from casualty state, vessel control, sea room and trend; make the appropriate call through the available independent path.
- 3Report that the fixed antenna is lost, give a checked position and state the assistance or advice required.
- 4Set the next update and MAYDAY trigger: loss of propulsion or control, casualty deterioration, fire/flooding, or loss of safe sea room.
Sense check: The communication describes both the present incident and the reduced capability created by the common mast/antenna failure.
| Command question | Evidence | Action |
|---|---|---|
| What is the priority? | Danger, trend, time, people, controls | Routine, urgency, distress or safety path |
| Who owns the yacht? | Named helm/lookout/navigation roles | Keep control throughout the exchange |
| Was contact made? | Acknowledgement and readable instruction | Log, update or use fallback |
| What changes next? | Measurable margin or casualty trigger | Escalate, divert, prepare or cancel |
Brief communication as part of command
A developing incident needs DSC/VHF, an accurate position, visual locating signals and crew communication while the yacht remains underway in traffic.
1. Preserve control
Name who owns helm, lookout, navigation and the immediate emergency before assigning the radio task.
2. Choose and execute
State the priority, DSC/voice/channel sequence, concise message and next update time.
3. Prove resilience
Name an independent fallback and the measurable trigger that escalates, changes route or prepares abandonment.
Sense check: The answer could be briefed to a real crew and still works if the primary antenna, operator or situation changes.
Common mistake or limitation
- A perfect radio script does not compensate for losing helm, lookout, casualty care or damage control.
- A powered fixed set after dismasting is not evidence that the masthead antenna path survived.
- Do not present an SRC procedure recital as proof of practical command or Yachtmaster exam competence.
- A fallback that shares the same power, antenna, operator or inaccessible stowage is not independent.
Recap
- Communication supports command; it does not displace it.
- State priority, procedure, roles, evidence and next update.
- Use a genuinely independent failure branch.
- This lesson supports revision and decision articulation, not practical competence certification.
