U.S. Coast Guard Homeland Security Gross Tons/Tonnage Towing Vessel National Center of Expertise A vessel’s approximate volume based on tons GRT: Standard, dual measurement systems: GT = Volume of enclosed spaces (tons) – exempted spaces per regulation (46 CFR Part 69) Simplified measurement systems: Length, depth, breadth modified by a coefficient: For example…GT = 0.67 LDB/100 (depends on hull shape) GT - ITC: All enclosed spaces modified by a coefficient: GT = K 1 V V = total volume of all enclosed spaces in cubic meters K 1 = log 10 V What is it??

U.S. Coast Guard Homeland Security Net Tons/Tonnage Towing Vessel National Center of Expertise Net tonnage (NT) = A vessel’s earning capacity NRT: Standard, duel measurement systems = NRT = Gross tonnage – deducted spaces Simplified measurement systems = Gross tonnage modified by a coefficient: NT for self-propelled non-sailing vessel = (GT)(0.80) NT – ITC: Volume of passenger and cargo spaces modified by a formula based on the vessel’s volume: NT – ITC = K 2 V C (4d/3D) 2 +K 3 (N 1 +(N 2 /10)) What is it??
