đ Key Concepts
⢠Gross tonnage vs. net tonnage â what each measurement is meant to represent on a vessel
⢠Spaces that are nonâcargo / not available for earning capacity and how they are treated in tonnage calculations
⢠Which spaces are considered deductible spaces under tonnage rules (e.g., navigation, safety, access)
đ Think About
⢠Ask yourself: Which of these spaces directly contribute to carrying cargo or passengers for hire, and which are mainly for access, safety, or ship operation?
⢠Think about the purpose of net tonnage: Is it supposed to reflect total enclosed volume, or the portion of the shipâs volume that can actually be used for revenueâearning service?
⢠For each listed space, decide: would tonnage rules likely encourage or discourage deducting this space from the gross tonnage?
â
Before You Answer
⢠For each option, decide if the space is used for navigation/operation/safety rather than cargo or passenger accommodation
⢠Recall that net tonnage = gross tonnage minus allowable deductions (spaces not available for cargo/passengers)
⢠Check whether all of the spaces listed are of the same functional type (e.g., all nonârevenue, operational, or access spaces) or if one is different.
