I have been thinking about the gap between ECDIS certification and actual bridge competence.
A valid ECDIS certificate proves that training was completed. But it does not always prove current familiarity with the system actually installed onboard. Different makers, software versions, menu logic, alarm settings, safety contours, route-checking functions and inherited configurations can all change how an officer interacts with ECDIS during a real watch.
The industry is good at checking certificates, familiarisation forms and inspection records. Those are necessary, but the harder question is whether the officer can operate the actual system confidently under watchkeeping conditions.
From a Master Mariner’s view, ECDIS competence is more perishable than we admit. It depends on recency, repetition and current system familiarity, not only on a certificate completed months or years earlier.

ECDIS Certification Is Not the Same as ECDIS Competence
