Clarify purpose and requirements
A personal memory, technical operating log and legally relevant ship log can have different requirements. Check the rules for your vessel, waters and use.
Capture consistently
Departure, destination, times, crew, weather, events and relevant counters form a useful baseline. Free text adds context but does not replace structured values.
Turn observations into follow-up
A technical anomaly should become an inspectable task or defect rather than disappearing among travel memories.
Keep corrections visible
Important historical records should not be silently overwritten. Time, author and reason create traceability.
