🔍 Key Concepts

• Radiotelephone logbook requirements for inspected vessels (46 CFR parts related to communications) • What makes a log entry legally valid and traceable • Standard record‑keeping practices: identification, orderliness, and corrections

💭 Think About

• Ask yourself: What basic information must every official log identify so that it can never be confused with another vessel? • Think about how logs are commonly used in investigations: Would sloppy, out‑of‑order, or erased entries be acceptable evidence? • Consider how corrections are normally made in official logs: Are erasures usually permitted, or are changes handled in another way?

✅ Before You Answer

• Verify whether the log must clearly show the vessel’s identity (name and/or official number). • Check if regulations expect that logs be kept in an orderly, chronological manner. • Confirm how errors in official logs are supposed to be corrected (e.g., single line through, initialed) and whether erasures are typically acceptable.
