Q

Which space(s) is(are) exempt when measuring gross tonnage?

🔍 Key Concepts

• Gross tonnage measurement and what it represents • Spaces that are included vs. excluded from tonnage calculations under 46 CFR Subchapter E (tonnage measurement) – verify in current regulations • The difference between working/control spaces (like wheelhouse, steering gear) and machinery or cargo spaces

💭 Think About

• Think about which spaces contribute to the vessel’s enclosed volume used for cargo, machinery, or accommodations, and which are mainly for navigation or control of the vessel • Ask yourself: are control spaces like the wheelhouse and steering gear room typically counted fully in gross tonnage, or are they given special treatment or exemptions? • Consider whether the location of a machinery space (above or below the uppermost continuous deck) changes whether it is included or exempt in gross tonnage

✅ Before You Answer

• Check in 46 CFR tonnage rules which spaces are specifically named as exempt from gross tonnage, not just generally described • Verify whether steering gear spaces and navigation/control spaces (like part of the wheelhouse used to control the vessel) are treated the same or differently in the measurement rules • Confirm if the rules distinguish between auxiliary machinery spaces above the uppermost continuous deck and other machinery spaces when deciding exemptions
