You are about to hand over the watch to the relieving officer at midnight. Describe the SMCP and standard communication framework for a complete and safe watch handover, including what information must be conveyed.

A. WATCH HANDOVER — STCW AND SMCP FRAMEWORK: STCW Code A-VIII/2 Part 4-1 specifies the minimum content of a navigational watch handover. MANDATORY INFORMATION TO COMMUNICATE: (1) POSITION: current position, last fix time and method, how long since last fix and DR since then; (2) COURSE AND SPEED: ordered course, actual course steered, speed ordered and log speed; (3) TRAFFIC SITUATION: all contacts identified on radar, their CPA/TCPA, actions taken or intended; (4) NAVIGATIONAL HAZARDS: next waypoint, next hazard, UKC at next shoal, time to alter; (5) WEATHER: current conditions, forecast, any change expected during the watch; (6) MASTER's STANDING ORDERS: specific instructions in force, any deviations authorised; (7) EQUIPMENT STATUS: any radar, nav aids, or steering gear defects; (8) TIDES AND CURRENTS: set and rate currently experienced; (9) COMMUNICATIONS: any outstanding radio schedules, VTS reporting points; (10) ANY OUTSTANDING ACTIONS or pending situations. CONFIRMATION PHRASE: "I am handing over the watch, the ship's position is [position], course [X], speed [X], I have informed you of all relevant information, do you accept the watch?" Relieving officer: "I accept the watch." Both sign the log. DO NOT HAND OVER if the relieving officer appears unfit for watch.

B. Write the ship's position and course in the log. The relieving officer is responsible for reading the log — verbal handover is not a requirement if the log is up to date.

C. Hand over when the relieving officer arrives on the bridge. State the course and speed only — the new watchkeeper should form their own picture from the instruments rather than being influenced by the outgoing officer's assessment.

D. The watch handover communication only needs to cover the compass course and any master's orders. Traffic situations are dynamic and should be assessed fresh by the incoming OOW.

A. IMO STANDARD MARINE COMMUNICATION PHRASES (SMCP 2001): The SMCP is an IMO publication (Resolution A.918(22)) providing standardised English phrases for maritime communications. LEGAL BASIS: SOLAS Chapter V, Regulation 14 requires that officers in charge of a navigational watch on ships required to carry a radio installation shall be proficient in the use of English. The SMCP provides the standardised language to fulfil this requirement. WHEN MANDATORY: (1) VHF bridge-to-bridge communications for collision avoidance; (2) Communications with Vessel Traffic Services (VTS) — initial call, position reports, intentions; (3) Distress, urgency and safety communications on Channel 16; (4) Communications with pilots during embarkation and passage; (5) Port authority and harbour control communications; (6) SAR coordination communications; (7) Communications with other vessels for manoeuvring in restricted waters. STRUCTURE OF SMCP: phrases are organised by function — external communications (VHF), internal ship communications, and safety-related phrases. Responses use standard acknowledgements: "I read you", "Stand by", "Say again", "Received". KEY PRINCIPLE: English is the working language of international maritime communications — if neither party is a native English speaker, both must use SMCP rather than their own language.

B. SMCP are voluntary guidelines produced by IMO. They are only recommended practice and SOLAS does not require their use — captains may use any language agreed between the two vessels.

C. SMCP apply only to communications with shore-based VTS. Ship-to-ship communications may use any mutually understood language including the officers' native languages.

D. SMCP are required only for passenger vessels. Cargo ship officers must be proficient in English but are not required to follow the standardised SMCP format.

A. SMCP COLLISION AVOIDANCE CALL — CORRECT APPROACH: Initial call on Ch 16 (then switch to a working channel, typically Ch 13 or 16): "Vessel bearing [bearing] from me, this is [vessel name] on VHF channel [xx], over." After contact: "I am the stand-on vessel. I intend to maintain my course and speed. Please confirm your intentions, over." OR if you are the give-way vessel: "I am the give-way vessel. I intend to alter course to starboard [or slow down] to pass astern of you. Do you agree? Over." KEY SMCP PHRASES: "I intend to alter course to starboard/port", "I am altering course to starboard/port", "I intend to stop my engines", "Please indicate your intentions." RISKS OF VHF COLLISION AVOIDANCE: (1) VHF agreements are NOT a substitute for COLREGs action — the give-way vessel must act in good time regardless of VHF exchange; (2) VHF agreements can create false confidence — the other vessel may not follow through; (3) Use call sign or vessel name to ensure you are speaking to the correct ship — "vessel ahead" is ambiguous; (4) Rule 8 requires action to be positive, taken in ample time — do not delay COLREGs action waiting for VHF response; (5) Document the exchange in the deck log.

B. Call the vessel on Ch 16 and agree to both alter to starboard. Once agreed by VHF, both vessels should proceed according to the agreement and no formal COLREGs action is needed.

C. VHF should never be used for collision avoidance — it creates legal liability by demonstrating awareness of the risk before action was taken. Use radar and take COLREGs action silently.

D. Use any language common to both bridges. SMCP only apply to VTS communications. Ship-to-ship collision avoidance VHF calls have no standardised format requirement.
