🔍 Key Concepts

• 46 CFR Subchapter M requirements for towing vessel records and logs • Difference between periodic (time-based) entries and event-based entries in the logbook • Who is responsible (owner/Master) vs when documentation must occur

💭 Think About

• Look at whether the question is asking how OFTEN to test/inspect, or specifically when you must record that it was done • Ask yourself: does federal regulation usually require safety‑critical actions to be logged on a fixed schedule (daily/weekly), or at a particular moment related to responsibility? • Consider when a Master becomes formally responsible for the condition of the vessel, its gear, and any tests/inspections already completed

✅ Before You Answer

• Verify if the regulation mentions time of day or day of week at all, or instead links the logging requirement to a change in command or watch • Check whether log requirements for tests/inspections are tied to the Master’s assumption of command rather than routine watch changes • Confirm that the choice you pick matches an event-triggered log entry, not just a convenient routine time, if that’s what the regulation describes
