🔍 Key Concepts

• Sanitary inspections on U.S. commercial vessels are usually required on a monthly basis unless a specific regulation states otherwise • Think about how many months are in the stated voyage duration • Relate the number of months to how many times a recurring monthly inspection would take place during that period

💭 Think About

• If a vessel must be inspected once each month, how many times would that occur over a three‑month voyage? • Does the count include both the start and end of the voyage, or just the recurring periods in between? • Which answer choice best matches the number of monthly inspections during a continuous three‑month period?

✅ Before You Answer

• Confirm that you’re thinking in months, not weeks • Make sure you are not multiplying by weeks per month—the inspection is per month, not per week • Verify whether a three‑month continuous voyage implies one inspection per month over that span
