🔍 Key Concepts

• Official logbook requirements in 46 CFR (particularly parts dealing with logbooks and reports to the Coast Guard) • The difference between informal working logs used on the bridge and formal legal records of the voyage • Which records the Coast Guard may inspect or require to be produced after an incident or voyage

💭 Think About

• Ask yourself: Which of these logs is intended as the formal legal record of the vessel’s voyage and operations, not just a working notebook? • Which log would be most important in the event of an accident, casualty, or investigation where the Coast Guard needs an official record? • Think about common bridge practice: which logs are often internal ship documents, and which one is recognized by regulation as an official document?

✅ Before You Answer

• Identify which option corresponds to a statutory, legally‑recognized logbook rather than a convenience log • Recall that some logs (like bell or rough logs) are supporting documents that feed into a more formal record • Verify in 46 CFR that certain vessels are required to maintain and, when requested, submit an Official Logbook to the Coast Guard or other authorities
