Watchkeeping: Bridge Procedures, Lookout, Handover and Record Keeping
Domain 5 tests bridge discipline: who is on watch, what is checked, how information is handed over, and what is recorded.
Bridge procedures
The officer of the watch is responsible for the safe navigational watch, while the master remains responsible overall. The watch must be arranged so the OOW can maintain a proper lookout without being distracted by chartwork or administration. Use the passage plan, fix positions at planned intervals, and monitor ECDIS or radar, echo sounder, AIS and alarms. The bridge should never be left unattended.
Lookout and handover
A proper lookout uses sight, hearing and all available means; at night, use radar and binoculars systematically. At handover, pass on the present position, course and speed, traffic, weather and visibility, machinery status, defects, pilot and master's orders, and outstanding items. Confirm that the relieving watch has understood.
Records
Keep the bridge logbook, bell book where fitted, engine movement book and radio log. Record position fixes, course alterations, soundings, weather, drills and unusual events. Entries must be factual, timed and signed. Do not backdate or erase; strike through and initial.
Worked example
You are handing over at 0400. Your checklist should include the 0350 fix, ship's head and speed, nearby targets with CPA and TCPA, the master's night orders, visibility and any ECDIS route alarm. If a target was in a crossing situation and the previous OOW altered course 10 minutes ago, state the alteration and the reason.
Traps
Handing over during a manoeuvre; leaving the bridge to check a chart; relying on one positioning source; failing to record a course alteration; using VHF for collision avoidance instead of applying the rules.
