The bridge team reports that ECDIS alarms are triggering frequently during a coastal transit, to the point that some alarms are being acknowledged quickly without full review ("alarm fatigue"). As Master, how should this be addressed?

A. This is normal and does not need attention — alarms are designed to be dismissed quickly

B. Review and adjust alarm parameters (e.g. safety contour, XTE limits) to be appropriate for the actual passage and vessel, rather than overly conservative defaults that generate excessive nuisance alarms, while ensuring this is done deliberately and documented — not simply muting alarms to stop the noise, which could mask a genuine alert

C. Alarm fatigue is solely a training issue for the individual watchkeeper, with no system-level fix

D. Disable all ECDIS alarms for the remainder of the passage

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
