You're asked in your oral exam why the IMO Standard Marine Communication Phrases (SMCP) matter to an OOW, beyond simply speaking English. What's the correct answer?

A. SMCP provide a standardised, simplified set of phrases for safety-critical ship-to-ship, ship-to-shore and onboard (multilingual crew) communication, reducing the ambiguity that a seafarer's second-language English or regional phrasing could otherwise introduce

B. SMCP are only relevant to GMDSS radio operators and have no bearing on bridge-to-bridge VHF or pilotage communication

C. SMCP are a legal requirement only on passenger vessels, not on cargo ships

D. SMCP replace the need for an OOW to hold a valid GMDSS radio operator's certificate

A. The tidal height at the time of transit to confirm sufficient under-keel clearance

B. The yacht's fuel consumption for that leg

C. The colour of the seabed shown on the chart

D. Only the distance to the next waypoint

A. Switch the ECDIS to standby mode and navigate by GPS position alone

B. Ignore it — ECDIS alarms are frequently false and can be left running

C. Assess the situation against the planned route and charted depths, take action to maintain safe water, and inform the Master if there is any doubt

D. Acknowledge and silence the alarm immediately so it does not distract the helmsman
