🔍 Key Concepts

• International Tonnage Certificate (ITC) purpose and when it applies • Difference between tonnage (GT – gross tonnage) and length in feet • Which vessels are subject to International Convention on Tonnage Measurement of Ships, 1969

💭 Think About

• Which of these options describes an international requirement rather than a domestic/operational one? • Look at whether the requirement is based on the ship’s size/measurement system or the ship’s trade route or inspection status. • Ask yourself: is an ITC primarily about where the ship trades, what certificates it already has, or how big it is by tonnage rules?

✅ Before You Answer

• Identify which choices are about measurement (tonnage/size) versus trade route or inspection. • Recall that an International Tonnage Certificate is linked to the ship’s gross tonnage (GT) under the international tonnage convention. • Verify which listed thresholds (if any) you’ve seen in association with ships that must comply with international tonnage measurement.
