The date of the last throat opening measurement for hooks is recorded in which record?

• A. AUX Weight Handling Equipment Record
• B. Hull History
• C. Deck Log
• D. Maintenance Ledger

Answer: (A)

Hook throat opening measurements are part of the records for weight handling equipment. The throat opening is a wear dimension used to assess hook condition, and keeping track of the date of the last measurement helps determine when the next inspection is due to ensure safe lifting operations. The official place for this data is the AUX Weight Handling Equipment Record, which is specifically designated for inspecting and recording measurements for auxiliary lifting gear. Other records serve different purposes: Hull History covers hull-related history, the Deck Log documents daily events and operations, and the Maintenance Ledger records general maintenance actions, but not the specific throat opening measurement date for hooks.
